I really enjoyed presenting my poster and sharing my work at #IWC2026Bologna today. If you are at the conference and want to learn about Aegilops tauschii, starch or GWAS pop by my poster (PO493) over the next couple of days 🌾

Great talk by Tzion Fahima on Kinase fusion proteins. We still have so much to find on resistance genes. Will we find kinases that provide resistance to viruses? #IWC2026Bologna

Amazing talk by Beat Keller on Resistance to pathogens and the importance of considering the whole system, including the pathogens and its avirulence genes . Pathosystems and resistance are much more complex that the classical zigzag model #IWC2026Bologna

Elisabeth Mazzucotelli illustrated great ressources for studying straits: wild and domesticated core collections, emmer NAM population but also collection of more minor wild relatives. All this linked to genomic ressources. Amazing time to be a geneticist! #FSTP5

Following the talks of Marco Maccaferri and Luigi Cattivelli, I can say that the future of durum wheat genetics looks bright with a lot of genomic tools recently or soon available for the community! #FSTP5

Live from #FSTP5! I’m exited to meet the durum wheat community, my new community! If you want to hear about the research that was carried out in SBCMV and WSSMV resistances and my research axes, come and meet at poster 112. I’ll also be giving a short talk on Friday

By posting for the first time in quite a while, I realized I didn’t inform here of my lab change! I’m now working within the GE2pop group of AGAP institut where I’m leading the research on #WSSMV and #SBCMV resistance in durum wheat. Stay tuned for updates on genetic basis of resistances to viruses!

Press release from Stand Up For Science France (cc @standupforscience.bsky.social)
Standing Up For Science in France
In the face of Trump’s administration’s relentless attacks on democratic institutions,
civil rights, science, public health agencies, environmental regulation, and climate
data collection, and as universities and research institutions across Europe also come
under increasing pressure, the French scientific community is taking action. On March 7,
2025, scientists, educators, students, and concerned citizens will march and rally in cities
across France to defend science and the humanities as pillars of democracy.
This mobilization is organized in solidarity with the "Stand Up For Science" movement in the US.

Corentin Maslard made a very nice presentation on effect oh heat and water stress on maize roots and microbial communities. Huge amount of work with multiomics. Roots exudates are the most affected. Heat stress have a mild effect, combined stresses are more than a sum. #ISRR12

Marcus Griffiths presented his work on the cover crop pennycress, either in field (with root washing and scanning the roots), and in mesocosm. In the field, they saw a large effect of accessions on root length, with QTLs, and a - correlation between root length and density #ISRR12

We entered the world of signaling today with the great talk by Malcolm Bennett. How do plants sense water? The main and somehow universal signal is ABA, whether the water stress is drought or compaction. It either repress lateral roots or induce barriers formation #ISRR12

In Takuya Koyama’s setup, substrate was divided in four and P distributed uniformly or more in a quarter of it. P uptake was more efficient when it was distributed in one patch, with a higher concentration. Roots branch more there without increase in total root length #ISRR12

Frederik van der Bom shows the results of his 4 years PostDoc in Australia, working on the interaction between root architecture and P uptake. The main thing is that the root should be able to reach the spots where P is available, depending of field management #ISRR12

Ricardo Giehl showed results obtained in the impressive @leibnizipk.bsky.social Phenosphere. Barley grown in low N with high N patches showed a higher branching in the patches, but total length os not affected. Screening a collection showed a large variability of this N plasticity. #ISRR12

Stephanie Klein presented a nice study on root angle in maize. Within the NAM population, some lines have steep or shallow roots, others are responsive to N. They identify a new QTL for root angle and did RNAseq, but H2 of responsiveness is too low for mapping #ISRR12
