Scientists in Nitrogen breakthrough

Barley: Discovery could aid developing countries
SCIENTISTS at the John Innes Centre have discovered an important component in the process of nitrogen fixation in plants.
The scientists have identified a key protein that facilitates the movement of calcium in plant cells. This movement of calcium signals to the plant that nitrogen-fixing bacteria are close by and triggers the development of nodules on its roots to house these bacteria.
Nitrogen is the most abundant gas in the atmosphere, and legumes are able to take nitrogen out of the air and incorporate it into their cells. This is possible because legumes have developed a symbiotic relationship with a particular type of soil bacteria that are housed within their roots. These bacteria take up (or ‘fix’) the nitrogen and pass it to the plant in exchange for sugars and other nutrients. This function enables legumes to grow with less nitrogen fertiliser.
Scientists have known for some time that the interaction between plants and bacteria depends on movement of calcium in plant root cells. This movement of calcium takes place in the central nucleus of plant cells. New research from the John Innes Centre lead by Dr Myriam Charpentier and Professor Giles Oldroyd discovered a set of critically important proteins; these proteins facilitate the calcium movement into the nucleus allowing the plant to transfer the information that the nitrogen-fixing soil bacteria are nearby. They believe this is now the nitrogen fixing symbiosis is established.
Although this calcium movement is limited to the nuclei of plant cells, it has a large impact on how the whole plant will grow.
Professor Oldroyd said: “This discovery demonstrates that there is a CNGC protein located at the edge of the nucleus in plant cells which controls the movement of calcium into the nucleus. This is an important step towards understanding nitrogen fixation in legumes and this understanding will help us to develop more efficient crops.”
Dr Charpentier added: “Although the presence of nuclear calcium signals in plants was demonstrated more than a decade ago, the exact identity of the nuclear calcium channel has remained a mystery. This research identifies the first nuclear calcium channel in plants. Calcium signalling is not only important for symbioses but also for many other processes happening in the plant during development and in response to the environment. Knowing the identity of the nuclear calcium channel will now enable us to better understand how plants use nuclear calcium signals to grow and respond to their environments.”
Professor Giles Oldroyd is leading a research group at the John Innes Centre that aims to transfer the ability to fix nitrogen to other types of plants, like wheat or barley. This would increase growth and yield for these crops – particularly in developing countries where farmers have less access to nitrogen fertilisers.

Plaid urged to move faster on farming reforms amid subsidy concerns
Welsh Conservatives accuse Plaid Cymru of failing farmers as ministers call for patience over changes to agricultural support
CONCERNS over the pace of farming reforms in Wales have intensified after the Welsh Conservatives accused the Welsh Government of failing to act quickly enough on promised changes to agricultural subsidy schemes.
The criticism comes after Welsh Government Rural Resilience and Sustainability Minister, Llyr Gruffydd, urged farmers to be patient as major changes to support payments continue to be developed.
Speaking to ITV Wales, Mr Gruffydd acknowledged that “change is difficult” as the government seeks to reshape agricultural support across rural Wales. The comments come at a time of growing unease among parts of the farming community over the future of post-Brexit subsidy arrangements and concerns about financial pressures facing farms.
The reforms centre on replacing previous support systems with a new approach intended to balance food production, environmental sustainability and rural resilience. However, some farmers and unions have warned that uncertainty over payments and policy changes risks damaging confidence in the sector.
Reacting to the minister’s remarks, Welsh Conservative Shadow Farming Minister, Andrew RT Davies, said Plaid Cymru was not moving quickly enough to deliver on commitments made to Welsh farmers.
Mr Davies said: “Change is not difficult – contrary to Plaid Cymru separatists’ claims.
“If the will is there, there’s no reason reforms can’t be implemented immediately.
“Plaid Cymru separatists must fulfil their promises to Welsh farmers now.”
The comments reflect wider political tensions over the direction of farming policy in Wales, with opposition parties arguing that delays and uncertainty are creating anxiety for agricultural businesses already facing rising costs and economic pressures.
Farming remains a major part of the Welsh economy, particularly in rural counties such as Pembrokeshire, Carmarthenshire and Ceredigion, where many communities rely heavily on agriculture and associated industries.
The Welsh Government has previously said changes to support schemes are aimed at creating a more sustainable long-term future for farming, though ministers have acknowledged the transition period will take time and may prove challenging for some in the industry.
The debate over subsidy reform is likely to remain a key political battleground as the government finalises details of its future support model and seeks to reassure farmers concerned about their livelihoods.

Pembrokeshire new potato harvest begins as first crop hits shops
Locally grown early potatoes arrive in stores as farmers begin lifting the first Pembrokeshire crop of 2026
PEMBROKESHIRE’S famous new potato season has officially begun, with the first crop of locally grown potatoes being harvested and delivered to shops across the county.
Farmers at Norton Farm began lifting the first Pembrokeshire new potatoes of the year this week, with the freshly harvested crop expected to reach local stores by Friday morning.
The arrival of Pembrokeshire new potatoes marks the unofficial start of the county’s summer growing season and is eagerly anticipated by shoppers keen to enjoy one of Wales’ best-loved seasonal foods.

Photographs shared by the farm show workers hand-picking potatoes from freshly turned soil as machinery lifted the crop from fields overlooking the Pembrokeshire countryside.
The potatoes, prized for their distinctive flavour and soft skins, benefit from the county’s mild climate and coastal growing conditions.
Brian Llewelyn a’i Ferched shared the news on social media, telling customers: “Arriving with us this afternoon!!!!” as excitement builds around the first deliveries.
Locally grown Pembrokeshire new potatoes are expected to be available in selected shops from around 10:00am on Friday.
For many in Pembrokeshire, the arrival of the first new potatoes is a sign that summer is just around the corner — and that it is finally time to get the butter on.

New Narberth farmers’ market to champion Pembrokeshire produce
LOCAL FOOD PRODUCERS GIVEN NEW MONTHLY PLATFORM
A NEW monthly farmers’ market is set to launch in Narberth next month, giving Pembrokeshire producers a regular space to sell and showcase food grown, reared and made in the county.
Pembrokeshire Local Food Partnership is launching the market at the Queen’s Hall, Narberth, on Saturday, June 13. It will then run monthly from 10:00am to 2:00pm.
The market has been developed in collaboration with local growers Rufus and Ffion, of Hael Natural Produce, based in Clunderwen.
Organisers say it will bring together a wide range of local food and drink producers, with stalls expected to include fresh seasonal produce, artisan foods, baked goods and speciality items.
Among those taking part are Spirit Wood Wales, Big Green Elephant, Foxhill Preserves and Pencw Cheese.
Pembrokeshire Local Food Partnership will lead on marketing and subsidise stall costs for the first three markets, in a bid to encourage strong early participation and reduce barriers for small and emerging producers.
The launch will also see Rufus and Ffion introduce a new local veg box scheme through Hael Natural Produce.
Rufus said: “I’m really excited to be launching my new veg box scheme at the farmers’ market.
“It’s a great opportunity to get fresh, locally grown produce directly to people in the community and to build something that connects people more closely with where their food comes from.”
Sue Latham, Coordinator of Pembrokeshire Local Food Partnership, said: “We are looking forward to creating a regular space in Narberth that supports local producers and gives the community consistent access to high-quality, local food.
“This market is about strengthening those connections and building something that can grow over time.”
Organisers are encouraging residents, visitors and food lovers to attend the launch and support the new initiative, which forms part of Pembrokeshire Local Food Partnership’s wider work to strengthen local food networks across the county.
