I just published this short article about making omega-3 PUFAs in transgenic plants, with the aim of putting a spotlight on some unanswered questions. I also flag the issue of transgene silencing in plant biotech as a problem that hasn't gone away! nph.onlinelibrary.wiley.com/doi/epdf/10....

Great to be drilling our GM camelina again, to determine the real-world resilience of our nutritional enhancement traits. This is the 13th consecutive year we have run GM camelina trials at @rothamsted.bsky.social, we like long term experiments!

It's 30 years to the day since the first GM crop product went on sale in the UK. To celebrate this milestone, here's a pic of my original tin with our new GM tomatoes engineered to accumulate omega-3 fish oils in the fruit. In collaboration with @johninnescentre.bsky.social & Susana Silvestre.

Great to be here in London as part of the BBSRC 'Accelerating impact in diet & health' impact showcase. We will be talking about the omega-3 tomatoes we have developed in collaboration with colleagues at @johninnescentre.bsky.social

www.telegraph.co.uk/gift/1bd9fd0... Some seasonally-relevant content, highlighting the nutritional value of smoked salmon. Our contributions on improving the omega-3s & astaxanthin are mentioned, along with expert input from Uni of Stirling & others. Merry Xmas (and eat more salmon)!

How healthy is smoked salmon really?

From the difference between farmed and wild varieties to the perfect portion size, here’s what you need to know about this festive staple

👏to Dr Susana Silvestre winning Best Poster at the Lipids in Diet & Health conference about her work unravelling how our GM camelina can efficiently accumulate important omega-3s. Great to see so much interest in our novel sustainable sources of these fatty acids!

On behalf of Plant Biotechnology Journal, very happy to support this meeting. I attended Plastid Preview meetings as an ECR (quite some time ago!) and they are vibrant and productive events.

🌿 A big thank you to Plant Biotechnology Journal for sponsoring the Poster Session at #PlastidPreview2025! 🧬✨ Your support helps early career researchers share their exciting work and spark new collaborations. @sebiology.bsky.social @johnathan-n.bsky.social

Great to see our collaborative study with Ed Cahoon and colleagues on the front cover of PBJ, describing our successful efforts to engineer the accumulation of astaxanthin in GM camelina seeds. Astaxanthin is a ketocarotenoid that is a powerful antioxidant & used in aquaculture feeds as a pigment.

In a great collaboration led by Ed Cahoon at UNL we engineered Camelina to make the pigment astaxanthin. We used genes from the Adonis plant - picture below gives a clue why! Successfully field trialled in UK & USA. Helping to make aquaculure more sustainable. www.rothamsted.ac.uk/news/camelin...

It was a pleasure to be part of the team that delivered this study, led by colleagues at Malaga (and including Noemi Ruiz Lopez who used to work on our omega-3 project). @rothamsted.bsky.social contributed with our world-class lipidomics capability, delivered by @lvm.bsky.social and Richard Haslam.

In addition to our big 4000m2 GM camelina trial at Suffolk, last week we also sowed some smaller plots on the @rothamsted.bsky.social Farm in Harpenden. This trial has a range of traits & combines GE with GM approaches. Nice pics by Lihua Han of the ISPG GM field trial team & site. Blue skies too!

Another GM camelina field trial successfully drilled this Saturday, under the azure skies of Suffolk. The @rothamsted.bsky.social Farm team of Mark, Samuil & Lewis did a great job in the hot & dusty conditions, but that's what testing in the real world is like. Thx also to Lihua Han for pix.

Important and impactful data from a joint study using our GM camelina oil. Great collaboration with University of Stirling, BioMar & NTNU in Norway. Our novel oil really works as a sustainable replacement for fish oil - exciting to see this confirmed again! www.fishfarmingexpert.com/fish-welfare...

Very happy to have contributed to this article. It's a topic I am very passionate about. We need to see significantly more translational and impact from all the investments in fundamental research. It is weird that many primary publications claim a big breakthrough, and then, nothing more happens!

Thank you to @johnathan-n.bsky.social from @rothamsted.bsky.social for visiting @ljmuofficial.bsky.social today. His talk on #plant #biotechnology showed how to tackle a global problem and develop a solution. Now there are plants producing beneficial oils for the benefit of society

Here's an update on our camelina transformation pipeline. Because we use a visual marker (DsRed) we can chip the primary transgenic seeds for non-destructive analyses. Compare that with other systems that require extended tissue culture stages, and camelina is a clear winner!

This should be an exciting session, exploring multiple aspects of translational and predictive biology. @meganlmatthews.bsky.social is the lead organiser and I am happy to provide additional support. Also pleased to acknowledge the support of PBJ for this session. See you all in Antwerp!

We have some great talks lined up for this session including Prof. Christine Raines, Dr. Wolfgang Busch, Dr. René Geurts, and Dr. Sanu Shameer! Abstracts due March 7!

Rothamsted welcomes latest advance of UK Government Precision Breeding Legislation. "This Act will make life much easier for creators and developers working with precision bred - specifically gene edited - crops" @johnathan-n.bsky.social Full story: www.rothamsted.ac.uk/news/rothams...

Here at @rothamsted.bsky.social we are fortunate to have a very large area of GM glasshouse. Here we are growing up enough plants to transform 18 different constructs, optimising the accumulation of EPA&DHA omega-3 fish oils. Camelina is the ideal crop for such an iterative approach.

www.rothamsted.ac.uk/news/rothams... Great that so many @rothamsted.bsky.social people contributed to making this event a success, interacting with MPs & policy makers. Also almost certainly the first time anyone has brought gene edited seeds in the House of Commons!

I don't get into the lab much (to the immense relief of everyone else!) but this afternoon I was screening some of our high Omega-3 lines for the presence of the DsRed marker - this event is homozygous & stable, making lots of EPA after growing in the field last year. That's a success!!

Happy Holidays! Here's a rather unseasonal pic from the garden today. I always associated Primulas with Easter, but climate change has altered all that (and not in a good way).

Just because it is the festive season doesn't mean we stop our experiments - lots of GM and GE camelina plants growing in our glasshouses. Happy Holidays!

An investigation by SSA into a recent UK Govt report charting further declines in farmland bird numbers in Britain raises serious questions about the scientific basis on which these statistics are collected and interpreted. Find out more 👇 www.scienceforsustainableagriculture.com/buttonpearsa...

Are Defra Ministers being misled by campaigning NGOs over farmland bird numbers?

A word about my profile pic (with the 'nice to see you.' strapline, appropriate for Bsky!) - I took this photo in May in Bedminster, Bristol, when I was part of a panel discussing food security (in a pub!). I lived & worked in Bristol for 12 years, and it's where my omega-3 project was born.
