We are thrilled to Host Sylvain Bischof today at LIPME in Toulouse

Apoplastic barriers are essential for nodule formation and nitrogen fixation in Lotus japonicus Establishment of the apoplastic root barrier known as the Casparian strip occurs early in root development. In legumes, this area overlaps with nitrogen-fixing nodule formation, which raises the possi...

Sorghum aerial roots producing mucilage and hosting bacteria that fix nitrogen from the air

Our latest article on biological nitrogen fixation on the aerial roots of sorghum has been published in @plosbiology.org. We thank the @energygov.bsky.social for supporting this exciting project.

Solanum pan-genetics reveals paralogues as contingencies in crop engineering - Nature Gene duplication and subsequent paralogue diversification are major obstacles to genotype-to-phenotype predictability.

🚨New paper published in @nature.com! Using pan-genetics across the Solanum genus🍅🥔🍆we reveal why gene duplications🧬are major contingencies in crop engineering. My postdoc work in the Lippman lab @CSHL, collab. with @katiejenike.bsky.social @mikeschatz.bsky.social chatz.bsky.social and many others!

Really pleased to transition from 2024 to 2025 with Tatiana Vernie's work on the evolution of the common symbiosis pathway published @pnas.org 🔽

We finally demonstrate that ☘️ have maintained a genetic pathway to engage with🍄for half a billion years!

Check our updated preprint lead by @malick-mbengue.bsky.social and Eve Teyssier⬇️

A discovery and a big question!

- LysM-RLK have played a symbiotic function for 450+ million years (yes, as old as the land plants ☘️ !)

- What if CO and LCOs were not essential for AM symbiosis after all ?

And @eveteyssier.bsky.social is on bsky!!

Above: The down-regulation of the ARES long non-coding RNA do not modify significantly the expression of its neighbouring genes. Below: The down-regulation of the ARES decrease the average length of the lateral roots (right) without affecting the main root length (left) or the lateral root density (middle).

🥳 Happy to share the publication of the last part of Thomas Roule's Ph.D. at IPS2 on the role of ARES lncRNA 🧬 in the modulation of Arabidopsis 🌱 root architecture. doi.org/10.1002/iub....

A great collaboration with the group of Federico Ariel 🧪
