Nikolas and I just published our insights on CLEs in plant–bio interactions. Too short to cover everything, but we hope it gets you also excited about these peptides. Thanks to @newphyt.bsky.social for the opportunity

What can we learn from the first GWAS on bryophyte immunity? Have these plants evolved immune mechanisms similar to or different from those of angiosperms? (Spoiler: both!) Our latest paper is out in PNAS! www.pnas.org/doi/10.1073/pnas.2532723123 #Marchantia #Colletotrichum #EVOteam #LRSV

4/9 After characterizing the infection strategy of Colleto (with the help and guidance of @baptistebio.bsky.social and @jacquet-chris.bsky.social), Karima soon realized that the #MyMarchantia accessions we have in our collection were not all sensitive to that beast !

🤷What’s new? Unlike many model legumes, Aeschynomene evenia forms symbiosis with rhizobia without Nod factors! This makes it a unique model to explore how plants balance immunity and symbiosis with specific, Nod-independent pathways. 🦠🤝🌱 3/9

This gene family, probably involved in the drought response of M. polymorpha, originates from a horizontal gene transfer from a fungi to the ancestor of land plant, later lost in seed plants. Studying Marchantia therefore enabled us to further understand how plants conquered the land! (14/18)

Plant root hairs for #FluorescenceFriday. Red signal from #Microtubules that are deposited right under the #PlantCellWalls, so stain the cell outline. I briefly added green cell wall fragments, which were incorporated at the base of hairs. But then the hairs continued to grow, so the tips are red.

The image shows fluorescent young side-roots of an Arabidopsis plant. From the main root, only one long, large epidermis cell can be seen. It is surrounded by green and red fluorescence, coming from an mCherry-tagged microtubule marker and an Alexa488-tagged cell wall marker. On both side of this long cell, small lateral roots grow out. They look like little thimbles. Their bases are green, then there is an intermediate yellow zone, then their tips are red. This is because the green cell wall marker was only added at a certain time point, and was then incorporated into the wall. But the roots continued to grow out longer, so the newly synthesized parts, the tips, don't have the cell wall marker. They only have the ever-present red microtubule marker.
