Ever wonder how flower petals can make such amazing patterns? Me too, and thanks to @nwonieuws.bsky.social, we will get to find out! www.uu.nl/en/news/biol... @petuniaplatform.bsky.social #plantscience #UtrechtUniversity #NWO #flowers #epigenetics

From aerial drone to quantitative trait locus: leveraging next‐generation phenotyping to reveal the genetics of color and height in field‐grown Lactuca sativa Understanding the genetic basis of lettuce color is important because these traits correlate with metabolites such as anthocyanins, which are known to have strong antioxidant properties. Furthermore,....

Check out the latest paper by the Snoek lab in @theplantjournal.bsky.social, a genetics study involving a large field trial with 200 lettuce genotypes phenotyped by a drone.

Great work by Rens Dijkhuizen, Bram van Eijnatten, Sarah Mehrem, @guidopmi.bsky.social & others!

Our Translational Plant Biology Team from @utrechtuniversity.bsky.social is well represented at #2025ISMPMI. Come and see our posters: P077 Inigo Banales, P095 Dmitry Lapin, P235 @scoolen.bsky.social, P412 Bart Schimmel. Too bad I cannot attend this year. Enjoy!

I’m honored to give a talk on ‘the role of pest-associated microbes in insect-plant interactions’ at the ‘International Society for Molecular Plant-Microbe Interactions’ congress in Cologne (July). #MPMI @mrogowska.bsky.social, @cuwelte.bsky.social, @robertsjansen.bsky.social, @guidopmi.bsky.social

Thanks. One correction😉. The lettuce LNR receptor is a RLK in contrast to the Arabidopsis RLP23 receptor. Convergent evolution to recognize NLP proteins.

A strong showing from Utrecht at #ICAR2025!

Catch us as speakers, session chairs and at posters #42, 50 and 240 tonight!

Congrats JJ. What a team together with Jeff and Brian! Well deserved. 🥳

I thank all co-authors for this work. By combining phylogenetics, structural prediction, and functional assays, we demonstrate that the isochorismate-based SA biosynthetic pathway emerged during Brassicales evolution.

🚨 We’re hiring–please spread the word! 🚨 Our lab at @thesainsburylab.bsky.social is looking for a pre-doc intern to join our research on plant immunity. If you’re a current undergrad/master’s or recent graduate interested in gaining research experience, please apply! tatsuyanobori.com

Ukraine is Europe!
We stand by Ukraine.

We will step up our support to Ukraine so that they can continue to fight back the agressor.

Today, it became clear that the free world needs a new leader. It’s up to us, Europeans, to take this challenge.

Alle media die dit beschrijven als ‘ruzie’, ‘a shouting match’ enz. geven Zelensky verantwoordelijkheid voor de onvoorstelbaar beschamende behandeling die hem ten deel viel. Hier zat een eervol mens tegenover de ergste bullies van het schoolplein. Verschrikkelijk.

Hi there. Welcome👍🏻

What is your take on DeepSeek @kamounlab.bsky.social ?

Seed tuber microbiome can predict growth potential of potato varieties - Nature Microbiology Time-resolved drone imaging of potato crop development and seed tuber microbiome data can be used to predict potato vigour, or growth potential, in next-season crops in trial fields.

Our latest research, "Seed tuber microbiome can predict growth potential of potato varieties," is now published online on Nature Microbiology! 🥔✨

Let's connect and grow ideas together!

New year, new paper! Now published in @nature.com. We identified and characterised diverse immune cell states in plants under pathogen attack. My postdoc work in the Ecker lab at @salkinstitute.bsky.social. A thread (0/n)

Very sad news. Great memories of my fellow downy mildew researcher across the Atlantic. He was a strong supporter of the Oomycete and MPMI communities. John passed away way too soon and will be missed.

www.nature.com/articles/s41... 🌱🚜 Excited to see our paper in @naturemicrobiol.bsky.social ! Amazing effort by @y-song.bsky.social in collaboration with TU Delft (Neil Budko, Elisa Atza) and the Dutch potato breeding industry to harness the power of the microbiome! 🥔🔬@utrechtpmi.bsky.social

What the world really needs is a vibe shift. Most people who don’t farm don’t think much about agriculture, & we’ve fallen into a trap of assuming there’s virtuous agriculture and evil agriculture. But we farm because we need to eat. Let’s use biotech and other tech to make less of a mess.

We have a vacancy for a PhD position with our recently started PMI PI @arsheed-sheikh.bsky.social at Utrecht University. Please apply via: www.uu.nl/en/organisat...

I am looking for a speaker for the "Plant Gene Expression Analysis" workshop at the PAG32 conference in January. There are no funds to support speakers unfortunately. Other confirmed speakers are @tralee-sci.bsky.social, Colleen Doherty and Ronan O'Malley. Please message me if you are interested!
