Fully Laden Shadow Fleet Tanker Breaks Down in Baltic Storm

On Friday, German response authorities had to deploy multiple tugs to rescue a broken-down shadow fleet tanker laden with Russian oil, sparking a small political furor. 

According to Germany's Central Command for Maritime Emergencies, the Eventin - formerly part of the Fractal Marine DMCC fleet - was under way from Russia to Egypt with about 100,000 tonnes of crude oil aboard. Off the coast of Ruegen, Germany, Eventin lost power and ability to maneuver, and it began to drift. 

"It is precisely this scenario that I have repeatedly warned against together with my colleagues from the Baltic region," said German Foreign Minister Annalena Baerbock on Friday. "Russia is endangering our European security not only with its war of aggression against Ukraine, which violates international law, but also with severed cables, moved border buoys, disinformation campaigns, GPS jammers, and also with dilapidated oil tankers."

The agency's Accident Command took over overall command of the operation, and it determined that an evacuation of the crew was not immediately necessary. The response vessel Arkona and the salvage tug Bremen Fighter were dispatched to attend to the stricken vessel and halt its drift. The command also put the response tug Bremen on standby and activated a boarding team trained to deploy via helicopter and assist with making a tow connection. 
 
At about 1500 hours, the Bremen Fighter made up a towline to the Eventin and successfully brought the ship's movement under control. However, the salvage was not yet over, and the responders had to contend with the difficult weather conditions of the Baltic in winter. Winds on scene were at Beaufort 7 as of Friday afternoon and were expected to strengthen as high as Beaufort 9 (strong gale, 41-47 knots). To provide additional holding power, two additional tugs, the Bremen and the VB Luca, were chartered by the shipowner to assist. The emergency response tug Baltic has also been ordered to reposition from the western Baltic Sea to a location nearer the scene as a precautionary measure. 

19-year-old Eventin is part of the Russia-facing "dark fleet," a pool of hundreds of anonymously-held tankers of high average age and uncertain governance. The vessel was owned by a reputable Norwegian tanker firm until after the invasion of Ukraine in 2022, when it was sold to an anonymous holding company in the UAE, Vaigai Lines. 

After its sale in August 2022, its new commercial operator was Fractal Marine DMCC, the Dubai-based tanker firm that was an early leader in providing alternative shipping services to Russian oil exporters after the invasion of Ukraine. Under Fractal Marine DMCC's control, Eventin frequently navigated to and from Russian oil ports, often disabling its AIS, according to OpenSanctions.org.  

In early 2024, Fractal Marine DMCC was sanctioned by the UK government for "operating in the Russian energy sector as part of Putin's shadow fleet." The company insisted that it was fully compliant with all regulations, but was unsuccessful in appealing the sanctions listing and liquidated its assets one month later.

On February 22, 2024 - the same day that UK sanctions on Fractal Marine DMCC were announced - Vaigai Lines took over as Eventin's operator, removing Fractal's name from the vessel's management record. Vaigai then resold the vessel to another anonymous single-vessel holding company, Laliya Shipping Corp, which has no listed address.

Eventin's ISM manager remains Wanta Shipping LLC, a firm with multiple ties to the former Fractal fleet. The vessel continued to call Russian oil loading ports as recently as this month, immediately prior to its breakdown in the Baltic. Eventin remains insured and classed by reputable Western entities. 

Though linked to Russia's oil export trade, Eventin, Vaigai, Laliya and Wanta are not named on international sanctions lists. As these firms are not officially blacklisted, private salvors may safely contract with them for Eventin's rescue, without the need to seek prior exemptions.


Dark Fleet Tanker Might Have Damaged More Subsea Lines if Not Stopped

Finland's National Bureau of Investigation (NBI) has found and recovered the missing anchor from the "dark fleet" tanker Eagle S, which is suspected of severing four subsea telecom cables and a high-voltage power cable in the Baltic on Christmas Day. The next step in the investigation is to determine when it came loose - before or after the authorities asked the Eagle S to raise the anchor it was dragging on the bottom.

On Dec. 25, Fingrid's EstLink 2 power transmission cable and four subsea telecom cables suddenly broke down. The outages corresponded to the position of the tanker Eagle S; Finland dispatched a police tactical team in a helicopter and asked Eagle S to divert, and the crew agreed to comply. 

In a sonar survey after the casualty, a drag line of about 50 nautical miles in length was found on the bottom. Eagle S' anchor was discovered at the end of the line, near the Porkkala Peninsula, and Swedish military salvors helped raise it to the surface on Sunday night.

The location where the damaged anchor was recovered happened to be near the place where Finnish authorities instructed Eagle S to raise her anchor. This is of interest to the authorities, as it raises questions about whether the incident could have been worse without government intervention. The tanker's onward route would have passed over the Estlink 1 power cable, as well as the Balticconnector gas line. 

"If the anchor only came loose during the hoisting, it is likely that the anchor could have caused further damage to the seabed infrastructure if the vessel had continued its journey," Detective Superintendent Risto Lohi of the National Bureau of Investigation said in a statement. 

New images released by the NBI show that the anchor's crown is cracked, and its flukes are much shorter than typical. Previous photos of the Eagle S - taken in years past, when she operated under a previous name - show that the tanker was originally equipped with normal Hall- or Speck-type anchors, like most merchant ships.

Bangladesh Could Lose Top Position in the Global Shipbreaking Market

With global ship demolition at record low levels, Bangladesh’s shipbreaking industry has reported that 2024 saw a massive drop in scrap ship imports. Only 144 ships were sent to Bangladesh last year for recycling, equivalent to 968,000 GT, the lowest since 2005. As the leading global ship recycling destination, Bangladesh usually processes at least two million GT of end-of-life ships, according to the sector’s data for 2023. The peak year for the Chattogram-based industry was in 2021 with 280 ships (2.73 million GT) demolished.

However, 2022 marked an inflection point as ship recycling imports fell to 1.14 million GT. At the time, factors such as the start of the Russia-Ukraine war were blamed for the drop. But disruptions in the shipping industry continue to multiply, leading to fewer ships being sent for demolition. This became exacerbated last year as Red Sea crisis led to demand for extra capacity in shipping, including older vessels designated for recycling.

Further, demolition prices fell significantly over the course of 2024, from a high of $600/LDT (Light Displacement Tonnage) in Q1 to $450/LDT by end of December, according to data by demolition ships cash buyer GMS. This has left many yards in South Asia in a state of limbo, with some opting for a temporary closure.

While an uptick in recycling markets is expected in 2025, the long-term sustainability of yards in Bangladesh will depend on how they pivot their operations for global environmental compliance. The Hong Kong Convention (HKC) on safe recycling of ships will take effect on June 26. Yards are therefore expected to comply with standards set by the HKC. But some industry analysts have said that Bangladesh has not done enough to get its yards certified under HKC. Unfortunately, this could see Bangladesh lose its top position in global ship recycling to India.

“With over $100 million funding from international donors, India has developed 120 green yards on the coast of Alang in Gujarat to recycle ships following the HKC. In contrast, Bangladesh has developed only five green yards in the last 10 years, which are not enough to compete with India. This means that Bangladesh is likely to lose its top position this year,” Anam Chowdhury, President of the Bangladesh Marine Officers Association (BMOA) told the Business Standard newspaper.

According to 2023 data by India’s ratings firm Care Edge, Bangladesh accounted for 46 percent of the global gross tonnage dismantled in the year. India was second, accounting for 33 percent.

A global study reveals a disturbing rise in early-onset gastric cancer, a disease once predominantly affecting older adults but now increasingly impacting younger populations. This shift in disease patterns, uncovered through a 15-year analysis, calls for urgent reevaluation of global health strategies and targeted interventions.

Historically, gastric cancer has been a disease primarily affecting the elderly. However, emerging research indicates a dramatic change: younger adults are now increasingly at risk, with cases becoming more aggressive in this demographic. This shift poses new challenges for prevention, diagnosis, and treatment, highlighting the urgent need to investigate environmental, genetic, and lifestyle factors that may be driving this troubling trend.

A new study (DOI: 10.20892/j.issn.2095-3941.2024.0159) published in Cancer Biology & Medicine by the National Cancer Center in China sheds light on the alarming rise of gastric cancer among younger adults. The study analyzes global, regional, and national data from 2003 to 2017, provides compelling evidence of a shift in the disease's epidemiology, with younger populations now bearing a growing burden of the illness.

The research draws from the GLOBOCAN 2022 database and CI5 volumesX-XII, revealing an estimated 968,000 new cases of gastric cancer and 660,000 deaths globally in 2022 alone. East Asia remains the epicenter of the disease. Males have higher mortality rates thanwomen across all geographic regions.
A weak correlation emerges between the disease's incidence and the Human Development Index (HDI), asseveral Asian countries with high HDI experiencing higher rates of gastric cancer. Despite a global decline in overall gastric cancer cases, the study identifies a significant uptick in younger individuals, especially in certain countries in Europe, Oceania, and North America, which signal a shift in the epidemiology of the disease. Researchers suggest that this change in young generations may be linked to evolving lifestyle choices, dietary habits, and increasing obesity rates. These findings underscore the critical need for more targeted prevention strategies and early detection methods that address the specific risks facing younger populations.

Dr. Wanqing Chen, the lead researcher behind the study, underscores the urgent implications of these findings: "The rise of early-onset gastric cancer is not merely a medical issue—it is a global health crisis. This alarming trend demands immediate attention and action. Our research calls for the development of specialized prevention strategies aimed at younger populations, to curb the impact of this growing health threat on both individuals and healthcare systems."

The implications of this study extend far beyond academic research. It advocates for age-specific public health interventions, emphasizing the need for early detection and tailored prevention strategies that address the changing landscape of gastric cancer. By focusing on younger adults, these measures could help reduce late-stage diagnoses, improve patient outcomes, and ease the financial burden on healthcare systems worldwide. With targeted action, there is a real opportunity to reverse the rising tide of early-onset gastric cancer, potentially saving countless lives in the process.

Official launch of Global Heat Health Information Network Southeast Asia Hub at NUS Medicine




National University of Singapore, Yong Loo Lin School of Medicine




The Heat Resilience & Performance Centre (HRPC) at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) has been officially designated as the Global Heat Health Information Network (GHHIN) Southeast Asia Hub, a recognition that underscores its leading role in advancing heat resilience. This designation highlights the Centre's expertise in addressing the growing challenges of heat-related health risks in the region. With this appointment, the Centre is poised to play a pivotal role in working with the region to shape strategies, research, and policies aimed at mitigating the impact of extreme heat on public health, demonstrating its commitment to building resilience in the face of climate change.

 

The GHHIN Southeast Asia Hub was launched at the first GHHIN Southeast Asia Heat Health Forum, a four-day forum that will serve as a pivotal platform for fostering partnerships, advancing evidence-based policies to manage extreme heat risks effectively in the region, and enhancing the region’s collective capacity to protect lives and livelihoods. The opening ceremony of the forum was graced by Guest-of-Honour, Dr Koh Poh Koon, Senior Minister of State, Ministry of Sustainability and the Environment, and Ministry of Manpower

 

Organised by the GHHIN Southeast Asia Hub, and co-sponsored by the World Health Organization (WHO) and World Meteorological Organization (WMO), over 200 delegates will be participating in the four-day forum. Against a global backdrop of more intense climate change incidents with more frequent and severe heat events, the forum is themed “Toward a heat resilient Southeast Asia: Enhancing livelihoods and wellbeing”.  The Forum will bring together global experts, policymakers, and researchers to discuss the growing challenges of extreme heat and its effects on human health, productivity, and urban resilience. Hosted in Singapore, this landmark event showcases collaborative strategies, community-driven solutions and innovative insights to address the urgent heat-related issues in the Southeast Asia (SEA) region and their global impact. The forum is supported by Wellcome, a global charitable organisation that focuses on science and research.

 

Addressing urban heat, workplace heat, and traditional and cultural approaches to heat management

Chairing the GHHIN Southeast Asia Hub, is Associate Professor Jason Lee, also the Director at the HRPC at NUS Medicine, who brings a wealth of research and translational experience that will help guide and accelerate the conversions specific to the SEA region.

 

His team spearheaded Project HeatSafe, which investigated the impact of rising temperatures on the health and productivity of people in Southeast Asia. The project has sparked important conversations throughout the region, inspiring discussions on how to replicate and refine its research methodologies for broader applications in the region.

 

A/Prof Lee said, “Leveraging Singapore’s strategic location and expertise in heat stress management, we aim to collaborate with our regional counterparts to tackle the unique and multifaceted challenges posed by rising temperatures in Southeast Asia. Unlike other regions, our tropical climate brings distinct hurdles such as high humidity compounding heat stress, the Urban Heat Island (UHI) effect exacerbated by rapid urbanisation, and socioeconomic disparities that leave outdoor and indoor workers particularly vulnerable. Our ageing population also faces heightened risks, making it imperative to empower individuals, communities, and society to thrive in an increasingly warmer world.”

 

As we build on past efforts to address the challenges of heat in Southeast Asia, it is essential to recognise that the regional heat health challenges can differ significantly from those in the Global North, such as:

 

High Humidity Compounding Heat Stress

  • In Southeast Asia, the chronic combination of high heat and humidity limits the body’s ability to cool down through sweat evaporation.
  • This exacerbates the physiological strain, leading to greater incidences of heat exhaustion and heat stroke compared to regions with lower humidity, posing a significant risk to outdoor workers and vulnerable groups.

 

UHI Effect and Rapid Urbanisation

  • Urban Heat Islands, which exacerbate the urban temperatures, are more pronounced in Southeast Asia due to rapid urbanisation and dense infrastructure, as well as reduced green spaces and cooling surfaces like water bodies.
  • Many Southeast Asian cities often lack the infrastructure to mitigate urban heat effectively, including low-income and informal housing areas particularly exposed to localised temperature spikes.

 

Socioeconomic Disparities and Outdoor and Indoor Worker Vulnerability

  • In Southeast Asia, socioeconomic inequalities exacerbate heat impacts, as a significant portion of the population relies on outdoor and indoor labour in agriculture, construction, manufacturing, and informal sectors, which are highly susceptible to heat stress.
  • Globally, 512 billion work hours were lost due to heat exposure in 2023, with the largest impact in low- and medium-HDI countries, including many in Southeast Asia. As a result of the work hours lost, it resulted in an estimated income loss of $835 billion.[1] [2]

 

Ageing Population and Vulnerability to Heat

  • Southeast Asia's population is ageing at a faster rate than many other parts of the world[3]. While the percentage of people aged 65 and above (7.9%)[4] is still lower than in regions like Europe or North America (19% and 17% respectively)[5], the pace of growth in this age group is significant. In countries like Singapore and Thailand (13.1% and 14.7% respectively)4, the proportion of elderly individuals is notable. For instance, Singapore has one of the fastest ageing populations in the world, with projections indicating that by 2030, about 25% of its population will be aged 65 and above.
  • Southeast Asia's ageing population faces heightened challenges in the context of extreme heat, as older adults are particularly vulnerable to heat-related illnesses due to physiological factors and pre-existing health conditions. The increased frequency and intensity of extreme heat exacerbate health risks, placing additional strain on healthcare systems. Ensuring the well-being of the elderly requires targeted interventions, such as improving access to cooling facilities, enhancing public health messaging, and developing community support networks to safeguard against the impacts of extreme heat in this vulnerable demographic.

 

HRPC outlines future plans as the GHHIN Southeast Asia Hub

As the newly launched GHHIN Southeast Asia Hub begins its critical journey, the next steps aim to build on the dynamic conversations initiated during the Forum. These steps will lay a strong foundation for regional collaboration, innovation, and progress in addressing the growing challenges of heat resilience in Southeast Asia. The Hub’s immediate priorities include:

 

  • Developing a Comprehensive Strategy and Workplan: Co-creating a roadmap that defines key milestones and measurable targets. This strategy will ensure that efforts are aligned with regional needs and that tangible progress is made toward building heat resilience.
  • Establishing a Stakeholder Network: Mapping out a Southeast Asia-focused network of partners and stakeholders across governments, academia, industries, and community organisations. This inclusive stakeholder map will be pivotal in fostering partnerships and promoting a coordinated regional response to heat health challenges.
  • Implementing a Knowledge-Sharing Framework: Creating a robust system to facilitate the exchange of expertise, best practices, and innovative solutions. This framework will encourage collaboration, reduce duplication of efforts, and accelerate the adoption of effective strategies across the region.

 

Through these actions, the GHHIN Southeast Asia Hub seeks to position itself as a leading regional hub, driving impactful collaborations and evidence-based solutions that safeguard lives and livelihoods against the escalating risks of heat stress.

 

“Together as a region, this is our opportunity to build stronger, and more heat-resilient communities,” A/Prof Lee added. “We are committed to face these challenges head-on and shape a more resilient Southeast Asia that can thrive in the face of climate change - for today, for tomorrow, and for future generations.”

Bologna, Italy – On January 7, 2025, the European Commission established the Cherenkov Telescope Array Observatory (CTAO) as a European Research Infrastructure Consortium (ERIC), furthering its mission to become the world’s largest and most powerful observatory for gamma-ray astronomy. The creation of the CTAO ERIC will enable the Observatory's construction to advance rapidly and provide a framework for distributing its data worldwide, significantly accelerating its progress toward scientific discovery.

“The ERIC will streamline the construction and operation of the Observatory in a way that will undoubtedly help the CTAO attract new talent and investment as it continues to grow,” stated Dr. Aldo Covello, Chair of the Board of Governmental Representatives (BGR). “The ERIC status provides the CTAO with the legal stability and administrative advantages it needs to be sustainable in its worldwide operations and impact.”

The CTAO ERIC was established with the international support of 11 countries and one intergovernmental organisation that contribute to the technological development, construction and operation of the Observatory. The BGR represents this group and has been responsible for the preparation of the ERIC.

“We are grateful to our founding members for their support and to the European Commission for reaffirming their confidence in the CTAO as a world-class research infrastructure,” said Dr. Stuart McMuldroch, CTAO Managing Director. “This milestone represents the culmination of years of dedicated planning by the diverse teams contributing to the success of the Observatory. With the CTAO ERIC, we now have a powerful instrument to consolidate our efforts and drive the project forward.”

The ERIC not only provides the Central Organisation with a formal framework to accept and operate the current telescope prototypes, but it also allows for the immediate start of construction for the full array of more than 60 telescopes across both telescope sites in Spain and Chile. On the CTAO-North site, where the Large-Sized Telescope prototype (LST-1) is under commissioning, three additional LSTs and one Medium-Sized Telescope (MST) are expected to be built in the next 1-2 years. Meanwhile, on the CTAO-South site, the first five Small-Sized Telescopes (SSTs) and two MSTs are expected to be delivered by early 2026. Thus, with the aid of the ERIC, the Observatory is expected to be able to operate intermediate array configurations as early as 2026. These sub-sets of the final arrays will already be more sensitive than any existing instrument, bringing the Observatory’s early science within reach.

The impact of the ERIC will extend beyond hardware, influencing several other key areas. In the coming months, the Observatory will prepare to integrate and operate advanced software designed to control the telescopes and their supporting devices on-site, as well as to manage data processing. Additionally, the ongoing recruitment campaign will continue across all CTAO facilities, including the CTAO Headquarters in Italy and the CTAO Science Data Management Centre in Germany, ensuring robust support for these developments.

The CTAO was promoted to a “Landmark” on the European Forum on Research Infrastructure (ESFRI) Roadmap 2018 and was ranked as the main priority among the new ground-based infrastructures in the ASTRONET Roadmap 2022-2035. Now, after years of extensive preparatory work, and with the final legal entity in place, the CTAO solidifies its standing in the global research community, facilitating synergies with other international organisations and observatories.

“The ERIC status strengthens the presence of the CTAO in Europe and its role as a key player in the European Research Area, but the support we have received and the scope of the CTAO ERIC’s influence goes far beyond European borders," explained Prof. Federico Ferrini, co-Managing Director. “To build and operate the world’s largest gamma-ray observatory that serves the ambitious needs of the global scientific community, we are counting on an increasing number of partners from around the world.”          

The CTAO ERIC Members are Austria, Czech Republic, European Southern Observatory (ESO), France, Germany, Italy, Poland, Slovenia and Spain. Additionally, Switzerland is an Observer, Japan is a Strategic Partner and Australia is a Third Party.

 

About the CTAO

The CTAO (Cherenkov Telescope Array Observatory; www.ctao.org) will be the world’s largest and most powerful observatory for gamma-ray astronomy. The CTAO’s unparalleled accuracy and broad energy range (20 GeV- 300 TeV) will help to address some of the most perplexing questions in astrophysics, falling under three major themes: understanding the origin and role of relativistic cosmic particles; probing extreme environments, such as black holes or neutron stars; and exploring frontiers in physics, searching for dark matter or deviations from Einstein’s theory of relativity. Additionally, the CTAO will play a key role in both multi-wavelength and multi-messenger fields in the coming decades thanks to its enhanced performance, which will allow it to provide fundamental gamma-ray information in the quest to probe the most extreme scenarios.

To cover its broad energy range, the CTAO will use three types of telescopes: the Large-Sized Telescopes (LST), the Medium-Sized Telescopes (MST) and the Small-Sized Telescopes (SST). More than 60 telescopes will be distributed between two telescope array sites: CTAO-North in the northern hemisphere at the Instituto de Astrofísica de Canarias’ (IAC’s) Roque de los Muchachos Observatory on La Palma (Spain), and CTAO-South in the southern hemisphere at the European Southern Observatory’s (ESO’s) Paranal Observatory in the Atacama Desert (Chile). The Headquarters of the CTAO is hosted by the Istituto Nazionale di Astrofisica (INAF) in Bologna (Italy), and the Science Data Management Centre (SDMC) is hosted by the Deutsches Elektronen-Synchrotron DESY in Zeuthen (Germany).

The CTAO is a Big Data project. The Observatory will generate hundreds of petabytes (PB) of data in a year (~3 PB after compression). Based on its commitment to Open Science, the CTAO will be the first gamma-ray observatory of its kind to operate as an open, proposal-driven observatory providing public access to its high-level science data and software products.

The CTAO Central Organisation (legally, the CTAO ERIC) is in charge of the construction and operations of the Observatory. This group works in close cooperation with partners from around the world toward the development of the Observatory. Major partners include In-Kind Contribution Collaborations that are developing essential hardware and software, in addition to the CTAO Consortium, an international group of researchers who works in the scientific exploitation of the Observatory.


This is an artistic rendering of the CTAO's northern hemisphere site or CTAO-North. The site already hosts a prototype of the Large-Sized Telescope, the LST-1 (top left), but the plan is for the site to host four LSTs and nine Medium-Sized Telescopes (MSTs) to cover CTAO’s low and medium energy range. The array is located on the existing site of the Instituto de Astrofísica de Canarias’ (IAC’s) Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands (Spain). At 2,200 metres altitude and nestled on a plateau below the rim of an extinct volcanic crater, the site currently hosts a variety of telescopes operating at different wavelengths, including the Telescopio Nazionale Galileo (TNG) and Gran Telescopio de Canarias (GTC), visible in the upper part of the image, as well as CTAO predecessor the Major Atmospheric Gamma-Ray Imaging Cherenkov (MAGIC) telescopes (not pictured).

Three classes of telescopes are required to cover the full CTAO energy range (20 GeV to 300 TeV). The "Alpha Configuration" details the approved configuration of the telescope arrays at the two sites for the Construction Phase of the CTAO Project. With this configuration, and for its core energy range (100 GeV to 10 TeV), the CTAO is planning 23 Medium-Sized Telescopes (MSTs). Four Large-Sized Telescopes (LSTs) and 37 Small-Sized Telescopes (SSTs) are planned to extend the energy range below 100 GeV and up to 300 TeV, respectively.

Parasite ‘matchmakers’ genetically alter plant cells to attract insects



Researchers have revealed how parasitic phytoplasmas manipulate plant biology to act as matchmakers, boosting male insect appeal by modulating hosts to attract more reproductive females.




eLife




Scientists have revealed a parasite’s role in boosting male insect appeal by modulating host processes to facilitate female attraction, thereby enhancing the parasite’s own transmission and survival. 

The study, published today as a Reviewed Preprint in eLife, is described by the editors as highlighting an important discovery: a bacterial pathogen's effector influences plant responses that in turn affect how the leafhopper insect carrier of the bacteria is attracted to the plants in a sex-dependent manner. They add that the research is backed by convincing analyses and sheds light on previously unexplored aspects of plant–bacteria–insect interactions.

Parasites – which rely on hosts for survival and propagation – have substantial control over their hosts, earning them the nickname ‘puppet masters’. This is especially the case for obligate parasites that rely on alternate hosts (vectors) for transmission. Phytoplasmas, parasites that cause disease in crops and other plants, are reliant on sap-feeding insects, such as leafhoppers, for transmission. They attract these vectors by triggering the growth of unusual plant structures and clustering of leaves through effector molecules, such as the virulence protein SAP54. However, the mechanisms underlying this process are largely unknown.  

“Our research focuses on the virulence protein SAP54, produced by phytoplasmas, which is known to induce the formation of leaf-like flowers in infected plants,” says lead author Zigmunds Orlovskis, a former postdoctoral scientist at the Department of Crop Genetic , John Innes Centre, Norwich, UK, and currently an independent project leader at Latvian Biomedical research and Study Centre. “Previously, we have demonstrated that leafhoppers are attracted to the leaves of infected plants, but this does not always depend on the presence of leaf-like flowers, so the exact mechanism is unclear.”

The team hypothesised that leafhopper attraction is influenced by proteins called MADS-box transcription factors (MTFs) that are involved in additional processes other than flowering, and this is what they set out to test.

They began by assessing the effect of SAP54 on male and female leafhoppers using choice tests – the insects were given the choice to feed and lay eggs on transgenic plants with and without SAP54. The team found that the leafhoppers produced more offspring on SAP54 plants than on those without. However, to their surprise, in the absence of male leafhoppers – there was no increase in offspring on the SAP54 plants. Similar results were seen with feeding preferences; the females secreted more honeydew (an indicator of feeding) on SAP54 plants in the presence of males and no obvious increase in honeydew when males were not present. Together, these results suggest that the attraction of female, fertile leafhoppers to SAP54 plants relies on the presence of male leafhoppers.

Next, the team focused on determining the signals behind these preferences. There were no differences in female leafhopper behaviours when they were placed in odour- and sound-proof containers, suggesting that the females are not using sound and smell for making their choices. This meant there must be some unique characteristic of the leaves in SAP54 plants that was attracting the females.

To explore this further, the team determined which genes were switching on and off in leaves of plants without and without SAP54 that were exposed to male and female leafhoppers. They found that SAP54 plants displayed a dramatically altered pattern of gene activity specifically when colonised by male leafhoppers, compared with the presence of female leafhoppers. Moreover, most of the genes belonged to cell defence and biotic stress pathways, and their activity was significantly lowered in the presence of the male leafhoppers. This could explain the female preference for plants with males already present. 

To address their original hypothesis that MTFs were involved in the leafhopper preferences, the team repeated the leafhopper choice tests in plants with mutated versions of different MTFs. They found that female preference for male-exposed SAP54 plants was dependent on a specific MTF protein called SHORT VEGETATIVE PHASE (SVP). Moreover, plants lacking SVP respond to male and female leafhoppers differently, suggesting that SVP influences the leaf’s response to herbivores in a way that is partly specific to the gender of the leafhoppers. 

“We found that SAP54 suppresses the plant’s biotic stress response pathways when exposed to male leafhoppers. This suppression is crucial in enhancing the plant’s attractiveness to female leafhoppers - the plants producing the phytoplasma effector SAP54 effectively act like a matchmaking service by drawing females to the males,” says Orlovskis. “The findings also suggest that the phytoplasma virulence factor improves male fitness”.

“Our research underscores the dual role of the phytoplasma effector SAP54 in altering host development and enhancing plant attractiveness to reproductive females in the presence of male insects,” concludes senior author Saskia Hogenhout, Professor and Group Leader in Advancing Plant Health, John Innes Centre. “This matchmaking effect is integral to the phytoplasma life cycle, because females lay eggs on the leaves and the leafhopper nymphs hatching from the eggs  will feed from the plant, thereby acquiring  the phytoplasmas that these insects may then vector to other plants. This finding provides profound insights into the extended reach of a single parasite gene in influencing host biology and vector behaviour.”

About eLife

eLife transforms research communication to create a future where a diverse, global community of scientists and researchers produces open and trusted results for the benefit of all. Independent, not-for-profit and supported by funders, we improve the way science is practised and shared. In support of our goal, we have launched a new publishing model that ends the accept/reject decision after peer review. Instead, papers invited for review will be published as a Reviewed Preprint that contains public peer reviews and an eLife assessment. We also continue to publish research that was accepted after peer review as part of our traditional process. eLife receives financial support and strategic guidance from the Howard Hughes Medical InstituteKnut and Alice Wallenberg Foundation, the Max Planck Society and Wellcome.
