How female 'Sherlock Holmes' changed Victorian Britain for the better

Working-class women often worked as private detectives in the Victorian era and Clara Layt’s work on the Strange Case of Colstoun House’s Smashed Eggs proved to be insightful

Female sleuths may seem the stuff of literary fiction: Mare of Easttown, Miss Marple, Enola Holmes. But startling recent research reveals that real women detectives were operating across Victorian Britain.

Hired by private enquiry agencies who needed agents who could infiltrate private homes by posing as housemaids or governesses, these women pursued cases that could be dangerous and seedy. Often, they were shadowing love rats. Men and women keen to use the new 1857 Divorce Act to jettison abusive or simply incompatible spouses employed female detectives to gather evidence that their other half was cheating on them. If you had servants, it was hard to be sure that your cook was not cooking your goose, from a legal perspective, and preparing to serve you a decree nisi for dessert.

One of the strangest Scottish cases of female detection is that of ‘Clara Layt’, who, in April 1897, was tasked by the London agency of Steggles and Darling with investigating suspicious events at Colstoun House, Haddington, by posing as a linen maid. Clara’s employer was the laird of Colstoun, William Hamilton Broun. He was concerned that various sinister happenings around the estate amounted to a malicious campaign against him that might pose a threat to his life and that of his wife, Lady Susan.

Living on tenterhooks

Rat traps had been sprung, eggs smashed in the henhouse, ponies had been mysteriously moved from their field and one had been injured and subsequently died. Hamilton Broun suspected that both his servants and his mail were being got at. He was living on tenterhooks and creeping about his country house in “silent boots” to try to catch the culprit. 

Clara Layt spent almost a month at Colstoun, one of the most ancient, continuously occupied properties in Scotland, in her embedded role: interviewing the gardeners and maids, the local solicitor and barber. Very unusually, her reports are preserved in Register House in Edinburgh.

They show how hard Clara worked. She had to get up and serve from 8am to 9pm as linen maid, mending sheets, tablecloths, and stair carpets. Meantime, she was conducting her below-stairs investigation while trying not to blow her cover. 

Her findings make explosive reading. This isn’t because there was, indeed, a murderer at Colstoun, but because Clara’s investigation shows the palpable miseries of the class system from both sides. Lying beneath Hamilton Broun’s paranoia that he might be physically attacked were vicious rumours and character assassination.

Accusations of sexual indiscretions

Lady Susan – daughter of the Marquess of Dalhousie, Governor-General of India – was 17 years older than her husband and from a much higher social echelon. Before they married, William Hamilton Briggs had been a medical officer in the Indian army. The gossip Clara Layt recorded suggests that the working-class employees of Haddington jeered at him for having taken his wife’s name and sneered at Lady Susan.

They claimed that the Queen snubbed the couple, and – most troublingly – accused Lady Susan of sexual indiscretions with soldiers in India that had led her first husband to divorce her. They said that “you can see from her face that Lady Susan isn’t a virtuous woman”.

The servants also mistrusted the financial situation at Colstoun. Some complained that they had not been paid; the master was suspicious and “boozy after dinner”; the house smelled bad. They worried that “things would go wrong”.

Adulterous ex-husband

In fact, the servants Clara interviewed misjudged Lady Susan. She was the victim rather than the villain in her first marriage. It was her first husband Robert Bourke, the Earl of Connemara, who had repeatedly and openly committed adultery, including with her own maid – infecting Lady Susan with a venereal disease that she spoke about openly in the court case in which she divorced him.

If others could “see from her face” that she was “not virtuous”, it is possible that she had tertiary syphilis: a condition that typically produces marked facial ulceration and deformity. She was dying: not of any psychopath’s knife, but perhaps of the silent legacy of sexual abuse.

Little wonder that, harrowed by his wife’s illness and the toxic atmosphere of social stigma that surrounded her divorce, Hamilton Broun suspected there were spies and slanderers around him who were in the pay of his wife’s ex-husband. He hired the detective agency to confirm his worst fears and, when the investigation drew a blank, refused to pay for Clara Layt’s work.

Squalor, not glamour

The case had a sad denouement. Steggles and Darling sued Hamilton Broun, arguing that they had done their job, though no villain had been identified. The Edinburgh papers delighted in the scandal. Clara Layt was reprimanded for using “coarse language” (mentioning venereal disease) and the judge announced that her testimony could be disregarded. Lady Susan died before the case was concluded. There were no winners here.

However, to those fascinated – as I am – by the realities of the detective profession for Victorian women, the Haddington case is illuminating. ‘Clara Layt’, I discovered after complex sleuthing of my own, was really, if improbably, called Clara Jolly Death. She was the wife of Leonard Jolly Death, another professional detective. A mother of two young children in Fulham, she was spending a month playing a servant in Haddington while feeling intensely homesick. 

Squalor, rather than glamour, was the norm for female detectives in this era. Many were working-class; many were parents. They were not always on the side of the angels, nor of their fellow women. But they forged a path that would eventually lead to women joining the police force and to recognition of women’s right to access all areas of public life.

Their work, while it was often criticised, drew attention to domestic abuse and to the inequalities Victorian women suffered in marriage. We can be glad that the servants’ hall is now a museum and that the modern female sleuth no longer has to darn while she detects.

Here’s How Labour and the Unions Could Take on Amazon

No unions, no public sector contracts.

New MPs entering parliament have been given a hearty welcome by Amazon, the retail and logistics behemoth widely accused of poor working conditions and union-busting.

In a congratulatory email sent to all new MPs, Amazon mentioned the recent union recognition ballot at Coventry’s BHX4 site where workers narrowly voted against union recognition. It said: “Across Amazon, we place enormous value on engaging directly with our employees and having daily conversations with them. We value that direct relationship and so do our employees.”

What the email didn’t mention was the union-busting dirty-tricks campaign that preceded the vote. Those “daily conversations” included mandatory hour-long union busting seminars, where Amazon officials told workers that unionisation meant they might miss out on pay rises given to other sites.

The email is just one sign that Amazon is taking no chances as it deals with a new government that could, in theory, reign its excesses in.

In June of 2022, Keir Starmer told the GMB conference that Amazon “should recognise the GMB.”

Yet 37 strike days and almost two years later, the corporate giant remains steadfastly non-union. After multiple refusals by Amazon to voluntarily recognise the union, last month workers in Coventry narrowly voted against unionisation.

A sustained anti-union campaign saw Amazon plaster the warehouse with anti-union posters, as well as QR codes that generated an email to the GMB requesting that union membership be cancelled.

Following the election, both the GMB and Amazon are anxiously watching the new prime minister to see whether his government will take action to confront the corporate giant.

If enacted, several of Labour’s manifesto commitments could curb the company’s vast commercial power in the UK and undermine its anti-trade union stance.

While not explicitly targeted at Amazon, the employment rights bill set to be introduced within Labour’s first 100 days of government – by 13 October – could remove some of the obstacles that the GMB faced in their battle to unionise the Coventry warehouse.

The GMB has sought access to Amazon warehouses for 12 years, and have been forced to do most of their organising and recruitment work outside the building gates. At the moment, there is no general right for unions to go inside workplaces and address the workforce – but the bill promises to change that, giving trade unions the right to enter workplaces and speak to workers.

The bill pledges to lower the threshold of support unions need in a workplace for holding a recognition ballot and allow workers to vote electronically.

Labour’s proposed reforms to public procurement, which have gone largely under the radar, could also impact Amazon.

Amazon made £222 million in 2022 from government and public sector contracts, with 99% of identifiable spending going on Amazon Web Services, the company’s cloud computing arm.

Large government contracts to Amazon Web Services are part of what makes the company such a formidable opponent for unions, as the company can use the massive profits it makes from cloud computing to offset the losses in retail that strike action inflicts, thereby riding strike action out.

At the 2023 GMB conference, Amazon striker Garfield Hylton asked Starmer: “What will a Labour government do to stop this flow of money to Amazon if they continue to refuse recognition of the workers’ union?”

Starmer, who described the GMB’s bid for recognition as a “fantastic campaign,” said that public money was not a “free-for-all” and that an incoming Labour government was entitled to ask “what’s the terms and conditions” it was given on.

While Labour’s initial “new deal for working people” pledged to reform public procurement, the pledge was dropped in May, as part of a general rowing back on the document.

While the updated new deal still promises to “make sure that trade union recognition and access is valued and considered as part of the process of awarding public contracts and determining strategic suppliers,” that pledge no longer forms part of Labour’s employment rights bill.

Instead, the document states that it will be implemented by a specific procurement bill. However, the king’s speech made no mention of a procurement bill, and no date for a proposed bill has been suggested.

Stuart Richards, a senior organiser for GMB, said: “At the end of last year, we saw Amazon being given public sector contracts worth around £900m while, at the same time, spending huge amounts of time and money to try and stop workers from organising their workplaces.

“The Labour party has a chance to reverse this. We’ve been given a commitment to link public procurement to unionised jobs and support for unionised industries. This commitment now needs to be delivered.”

Whether Labour reform procurement or not, Amazon isn’t taking any chances. Faced with new legislation, and the GMB’s close relationship with Labour as one of its biggest trade union donors, the corporate giant has launched a new lobbying offensive.

Behind the scenes, the company is buttering up newcomers to parliament.

New MPs have been invited to attend a welcome reception for new MPs that is supported by Amazon.

The event is hosted by the House magazine, a publication for the Houses of Parliament. According to the invitation: “This event is kindly sponsored by Amazon. Amazon has been in the UK for over 25 years, employing over 75,000 people across retail, technology and the creative industries, and supporting 100,000 UK-based SMEs to reach their customers.

“You will be able to engage with their team to find out how they can help support you as you represent your constituents.”

One new Labour MP has responded to Amazon’s overtures. On LinkedIn, MP for Swindon North Will Stone wrote: “Had the pleasure of visiting the Amazon BRS2 fulfillment [sic] centre today! It was interesting to take a peek at the technology being used on site and hear about their plans for introducing more green energy on site.”

Back in the summer of 2022, workers at BRS2 were part of a wave of wildcat strikes that broke out over pay and conditions. In November 2023, the GMB protested outside the Swindon depot in solidarity with strike action taking place in Coventry.

David McMullen, a GMB Organiser, said: “It’s not just in the Midlands where members are being underpaid and we aim to highlight this in Swindon.”

Labour appears to already be working closely with Amazon’s cloud computing department.

On 25 July, the minister for science and technology Peter Kyle announced that the government would match-fund a contribution made by Amazon of £8 million in cloud computing storage access to UK Biobank, a health database.

Kyle said: “This is just the start of our plan to work hand-in-hand with industry and academia, to harness the power of life sciences to grow our economy and boost healthcare.”

Kyle isn’t the only minister seemingly undeterred by Amazon’s flagrant union-busting. Last week, culture secretary Lisa Nandy publicly welcomed Amazon’s investment in the UK creative industries, after the US company acquired Bray studios. Nandy said the move would ensure the studio continued to “play a crucial role in our first-class screen industries.”

Six Companies Own 60% of UK Vets, and Workers Are Sick of It

Poorly kittens are big business.

A protestor outside Valley Vets in South Wales

When Valley Vets, a veterinary practice in South Wales, was bought by VetPartners in April 2017, there was no sign for pet owners that the independently owned outfit had been snapped up by a private equity firm; the practice retained its name, branding and staff.

Seven years later and a noisy picket line outside Valley Vets should help any pet owners still in the dark over who really owns their vet.

The strike – the first ever at a UK private veterinary practice – is over the harm that the for-profit model has inflicted on animals and veterinary staff alike. On the picket line, vets, animal support staff, nurses, and receptionists hold up homemade placards: “Pets before profits”; “Freedom from high fees”; “FFS: fair pay, fair fees, smaller profits.”

Workers at Valley Vets walked out on 16 July. After an initial 15 strike days, they decided to stay on strike until the end of August.

The crux of the strike is money: staff don’t make enough of it; pet owners fork out too much of it; and with an estimated value of £3bn, VetPartners could afford to hand over much more of it. Workers are demanding that the lowest-paid workers be paid the real living wage of £12 an hour, with pay rises in line with inflation for the rest.

Pet care wasn’t always big business. Until a legal change in 1999, only qualified and licensed vets could own a veterinary practice, meaning that vets tended to be independent practices or small local chains. “Back then, it was normal for veterinary surgeons to work in a practice, buy into the partnership and end up as a partner at their own practice,” said Suzanna Hudson-Cooke, chair of the British Veterinary Union (BVU), part of Unite.

Deregulation chipped away at the small business model, allowing corporations to quietly gobble up clinics. In 2013, only 10% of vet practices were owned by the “big six”: Pets at Home, CVS Group, IVC, Linnaeus, VetPartners and Medivet. Fast-forward to 2024 and it’s 60%.

VetPartners, owned by the private equity firm BC Partners, isn’t alone in keeping its clinics’ former brand identities intact when it acquires them. Four of the big six are guilty of the practice, leaving pet owners no inkling that their local veterinary practice is now part of a multinational corporation.

Linnaeus is owned by American chocolate giant Mars, who are also behind pet food brands like Whiskas. Among Medivet’s investors is LGT Capital Partners, a Swiss private equity vehicle owned by the Liechtenstein royal family. IVC – the biggest of the six – is owned by Nestlé and private equity firms Silver Lake and EQT.

The Covid-19 boom in pet ownership made the sector attractive to investors: during the pandemic, more than 3.2m UK households are thought to have taken on a pet. More than half of UK households – 57% – now own a pet.

The big six aren’t just snapping up veterinary practices, but also related facilities: diagnostic laboratories, referral centres, out-of-hours suppliers, crematoriums, pharmacies, locum agencies and veterinary nursing schools. They’re also investing heavily in upping the standard of care available for animals. From MRIs to oncologists, and behavioural experts, treatment options are more sophisticated – and expensive – than ever.

Treatment costs for animals have skyrocketed: over the last two years, the BVU says that Valley Vets has put up fees by 25%. Fees have risen so high that treatments often cost more than pets are insured for. “Back in the day, we would consider breaching a pet owner’s insurance policy to be an exception,” a vet from Valley Vets, who asked that Novara Media not use their name for fear of retaliation. “Nowadays, it happens all the time.”

The Competition and Markets Authority (CMA), the government competition regulator, launched an investigation into the veterinary market in 2023 after identifying “multiple concerns” about the domination of the veterinary market by the big six. Among these concerns was that acquisition sprees and investment mean corporations have an incentive to “offer and promote highly sophisticated treatments.”

Put simply, having spent vast quantities of money on facilities and treatments, vets feel under pressure from their corporate owners to claw that money back – often at the expense of pet owners. Staff at Valley Vets told Novara Media they feel under pressure to charge for every small thing and can be subjected to audits on so-called “charge leakage” – money “lost” when a service isn’t charged for.

The CMA is also investigating the practice of referring a pet for testing at another service owned by the same company – often without veterinary staff realising they are doing it. Sometimes true ownership is so well-disguised that “the people working in the practices won’t even know that an external service is actually owned by the same parent company,” said Hudson-Cooke.

Corporations have banked on our increased devotion to pets translating into a readiness to spend more money on them. CVS’s latest annual report described pet care makes as a “favourable sector” given the “continued humanisation of pets and appetite for innovation.” And they’re right: a 2022 Dogs Trust poll suggested that one in 10 UK dog owners have gone into debt to pay for their dog’s care.

Staff at Valley Vets say that the steep rise in fees has led to pet owners being forced to reject treatment on the basis of cost. At its starkest, vets are seeing more “economic euthanasia”: pet owners opting to put down an animal with a good chance of recovery because they can’t afford to treat them.

“Not being able to help animals, which is what we’ve been trained to do and what we love to do, is causing staff distress,” said the Valley Vets employee.

Corporatisation has also meant increased workloads: Valley Vets staff report seeing a new animal every 15 to 20 minutes for hours. Not only is this stressful for staff, but it means that the chance of making a mistake ­- accidental overdose, admitting the wrong animal, delivering incorrect news to an anxious pet owner – shoots up.

It’s the largely female support staff at the practice, paid pennies above the minimum wage, at the sharp end of rising fees. “They get shouted out by a stressed out angry client whose dying dog they cannot afford to help,” said the Valley Vets vet.

Hudson-Cooke isn’t dewy-eyed about the old vet business model, which had poor employment conditions and pay. But at least vets had “clinical autonomy”.

“When the practice is owned by a veterinary professional, decision-making about the reinvestment of profit centres on clinical matters,” Hudson-Cooke said. “When your company is owned by private equity, reinvestments are made on the basis of generating more profit.”

Ireland, Wales and the scholar who helped unravel their Celtic connections

Simon Rodway, Lecturer in Celtic Studies, Aberystwyth University
Wed 4 September 2024 at 11:09 am GMT-6·5-min read
THE CONVERSATION


Ireland and Wales share more than just geographical proximity; they have deep cultural and linguistic connections. And this year marks the centenary of a groundbreaking work which explored the relationship between the two countries.

Ireland and Wales: Their Historical and Literary Relations was written by the Irish scholar Cecile O’Rahilly in 1924. Her legacy in the field of Celtic studies continues to resonate, 100 years after her book was first published.

The Welsh and Irish languages are close relatives, descended from a common Celtic ancestor. It seems plausible, if much less open to proof, that the Irish and Welsh also inherited cultural and literary features from their Celtic-speaking ancestors.

One striking example is the role of the professional praise poet, a revered figure in both Irish and Welsh societies. Classical authors note that poets in ancient Celtic Gaul (present-day France, Belgium and Luxembourg, as well as parts of the Netherlands, Germany, Switzerland and northern Italy), held a similarly esteemed position. The word for “poet” in Gaulish, bardos, shares its roots with the Middle Irish word bard and the Welsh bardd. It’s a linguistic link that underscores their shared cultural heritage.

Irish literature offers vivid examples that closely mirror classical descriptions of ancient Gaulish society. Notably, warriors were said to keep severed heads as trophies and fierce competitions to the death at feasts determined who would claim the choicest cut of meat. These examples led to the theory that a relatively uniform Celtic culture once spanned the Celtic-speaking regions of antiquity, with Ireland preserving these traditions the longest, partly due to the fact it never became part of the Roman Empire.

Wales, on the other hand, was profoundly altered by its absorption into the Roman province of Britannia. The medieval Welsh adopted the Trojan Brutus as their ancestor, and idolised the Roman general Magnus Maximus.

The Welsh word Gwyddel (Irishman) derives from gŵydd (wild), and so literally means “savage”. The gulf between Irish and Welsh was facilitated by the fact that major phonological (the sounds in a particular language) changes to both languages obscured their historical relationship. No doubt the 7th-century Irish who borrowed the Welsh word Gwyddel as a term of self-definition (it gives us Gael today) were blissfully unaware of its original meaning.

Despite the fact that the medieval Welsh saw the Irish as being just as alien as the English, they were in frequent contact with them. There were Irish-speaking communities in parts of Wales, until the 7th century, as can be seen principally from bilingual inscriptions carved into stones in Irish and Latin.

Welsh churchmen such as the family of Sulien of Llanbadarn Fawr, 11th-century bishop of St Davids, were educated in Ireland. And Gruffudd ap Cynan, king of Gwynedd from 1081 until his death in 1137, spent his youth exiled in Ireland. He returned to north Wales with Irish soldiers to reclaim his throne. Day-to-day commerce across the Irish sea is also reflected in both Welsh and Irish literature.

Cecile O’Rahilly

Born in 1894 in County Kerry, O’Rahilly’s academic journey began in Ireland but her work soon took her to Wales, where she won a scholarship to pursue a master’s degree at Bangor University. She submitted an essay to the National Eisteddfod Welsh cultural festival in 1920 and ended up winning. The essay was the seed that grew into her seminal book, which explored the complex relationship between Ireland and Wales during the middle ages.

She remained in Wales, teaching French at a number of different schools, until 1946 when she took up a post at the Dublin Institute for Advanced Studies. She later became a professor there, the first woman to hold the post. O’Rahilly lived in the Irish capital with her Welsh companion Myfanwy Williams until her death in 1980. She is best known today as the editor of the epic Irish saga Táin Bó Cúailnge (the Cattle-Raid of Cúailnge), released in 1967.

O’Rahilly did not return to the question of the relationship between medieval Ireland and Wales in print. Nonetheless, her work was pioneering, but it also opened up debates that continue to this day.

Debates

Among the discussions arising from her work, scholar Proinsias Mac Cana and others, posited plenty of Irish influence on Middle Welsh tales such as Branwen, one of the earliest surviving Welsh prose stories.

But given their shared heritage, some similarities might date back to prehistoric times rather than the medieval period. They could also have arisen by independent generation, or have been independently borrowed into the two traditions from a third source, such as Latin literature, for example. A colleague of mine, Patrick Sims-Williams, has shown that it is difficult, if not impossible, to choose definitively between these possibilities.

The rise of “Celtoscepticism” in the late 20th century has challenged traditional views of Celtic identity, namely that there was no uniform shared culture among Celtic speakers over time and place. It has led to the retreat of individual scholars within Celtic studies departments into their own areas of expertise, rather than broader comparative work.

Scholars like Cecile O’Rahilly, who expertly navigated both Irish and Welsh sources and was fluent in both languages, are increasingly rare. But as new generations of experts explore these connections, the shared heritage of these two nations continues to offer fresh insights.

Children’s behavioral problems are linked to higher hair cortisol levels


This hormone, excreted by the body to respond to situations of stress, accumulates in the hair and is an indicator of a long-term stress level

Cortisol is the hormone secreted by the body to respond to stressful situations, so measuring the concentration of cortisol in the hair is very useful in analysing chronic stress. “Cortisol is usually present in the blood, saliva and urine, among other places, and indicates a momentary level of cortisol; however, cortisol accumulates in the hair, and that points to a degree of stress in the longer term, in other words, chronic stress,” explained Ane Arregi-Otxotorena, a researcher in the UPV/EHU’s Faculty of Psychology. To distinguish between momentary stress and chronic stress, Arregi uses a clear example: “The stress that occurs when you’re going to buy bread one day and you realize you haven’t got any money on you, is not the same as when you know you can’t afford to buy bread on a daily basis.” 

The researcher in the Basque Environmental Health Research Group (B-EHRG) used hair samples of 11-year-old children to assess chronic stress. To conduct the research she extracted data from the INMA project; the INMA (Environment and Childhood) project gathers all kinds of data on children and families, starting with the mother's pregnancy, for long-term research purposes.  

So the research concluded that, firstly, major behavioural problems are related to higher levels of cortisol in the hair. In addition, “we saw that maternal stress is related to children’s behavioural problems. This means that maternal stress can also influence children’s cortisol levels through their behavioural problems. Somehow along this two-stage path,” Arregi explained. 

Cortisol level is also influenced by environmental noise 

Secondly, they also found something they had not expected: “Higher exposure to environmental noise is associated with lower cortisol levels. We saw that the higher the noise level is, the lower the cortisol levels are. When classifying the analysis by sex, this relationship was only significant in the case of the boys.” According to the researchers, “the initial acute stress caused by noise may lead to a temporary increase in cortisol levels, but the chronic stress caused by long-term exposure to high noise levels can reduce the level of cortisol”. To confirm the results relating to noise, and which were unexpected, the same research will be carried out within the broader European Athlete (Horizon 2020) project. 

Environmental, social and individual factors 

Broadly speaking, “in our research we detected these two factors, but that does not mean that other factors are not related, but we did not find any other kind of relationship”, explained Arregi. “It is important to give these pieces of research a broader perspective while taking more than one stressful factor into account.” So a model was created to investigate the relationship between environmental, social and individual factors and the cortisol concentration in children's hair. All the factors that may influence stress and which appear in the literature were taken into account: for example, green and blue spaces, air pollution, environmental noise; family and school relationships, parental stress level; sleep problems, physical activity, age, sex, etc. 

As the UPV/EHU researcher pointed out, “much remains to be investigated relating to the factors that influence hair cortisol levels in children and young people, and studies so far have not taken into account the simultaneous influence of many factors”. The model was created to tackle this. Arregi explained that in the model it is important to take many factors into consideration: “From now on, the model will allow us to find out which variables should be taken into account when measuring the cortisol level in the hair and which should not.” 

Future research would need to use this more complex approach to better understand the determinants of cortisol in children’s hair; indeed, simultaneous exposure to various environmental, social and individual factors may influence the concentration of cortisol in the hair. Children being under the influence of chronic stress is related to many health problems; “childhood and adolescence are very vulnerable stages, because they are stages of rapid development. It is very important to know how different factors influence the health of children and adolescents at this stage so that they can become healthy adults”, said the researcher. 

“We believe that hair cortisol may be a useful tool when assessing how environmental exposures impact chronic stress. In short, this may help in the deployment of effective public policies; in fact, knowing what can cause the chronic stress of the population in a specific location may make it easier to implement policies to prevent it,” she concluded.

Unlocking peach growth mysteries: a new gene analysis method

In a notable advancement, scientists have developed an efficient gene functional analysis method for peach seedlings, overcoming longstanding hurdles in genetic transformation. Utilizing a TRV-based vector system, this innovative approach induces high-frequency gene silencing across diverse plant tissues, enabling in-depth analysis of genes essential for growth and development. The streamlined process notably shortens the transformation and analysis timeline to just 1.5 months, accelerating advancements in horticultural research.

Peach, a valuable crop within the Rosaceae family, has historically faced challenges in genetic research due to the lack of robust transformation techniques. Current methods are often limited by tissue type and developmental constraints, hindering functional gene studies. While gene silencing methods like virus-induced gene silencing (VIGS) have shown promise, their application in peach has been restricted by technical complexities. These challenges underscore the urgent need for more flexible and effective gene analysis techniques.

Scientists at Henan Agricultural University have addressed this gap with a novel TRV vector-based method, as reported (DOI: 10.1093/hr/uhae155) in Horticulture Research on June 3, 2024. The technique employs a three-step procedure to efficiently silence genes related to key plant architecture traits, such as branch angle and height. By breaking down existing barriers in genetic transformation, this method offers a valuable tool for researchers exploring the genetic underpinnings of plant growth.

The study’s method begins by removing the seed coat and one cotyledon from germinated seeds, followed by vacuum infiltration with Agrobacterium containing TRV vectors. The seedlings are then grown in soil for phenotyping. This approach achieved gene silencing rates between 48% and 87%, effectively targeting genes like PpMAX4 and PpWEEP. Notably, silencing PpMAX4 increased lateral branching and root mass, while PpWEEP silencing resulted in pendulous growth in dark conditions. The method also succeeded in silencing multiple homologous DELLA genes, addressing functional redundancy and enabling detailed analysis of gene roles in peach growth and development.

“This method transforms our approach to gene functional analysis in peach and potentially other woody plants,” said Dr. Jiancan Feng, one of the lead researchers. “By overcoming technical barriers in genetic transformation, it provides a highly efficient tool to investigate genetic functions that influence key traits in seedlings.”

The method's potential extends beyond peach, offering promising applications in breeding programs for various woody species. By facilitating precise analysis of genes linked to growth traits, this approach could significantly impact tree genetics research, supporting targeted breeding strategies aimed at enhancing crop resilience and performance. Future studies will focus on optimizing transformation efficiency and exploring its use in other economically important species.
