EPP1 is an ancestral component of the plant Common Symbiosis Pathway The success of plants on land has been enabled by mutualistic intracellular associations with microbes for 450 million years ([Delaux and Schornack 2021][1]). Because of their intracellular nature, th...

So happy to see the latest preprint of the team out! www.biorxiv.org/content/10.1...

Des écosystèmes entiers s’effondrent sans bruit. Pourtant, les débats restent centrés sur notre confort, notre économie, notre climatisation. L’humain au centre, comme toujours.

En Méditerranée, des températures de surface de la mer ont atteint 32°C, avec une anomalie thermique de +6,21°C.

Exploring fern pathosystems and immune receptors to bridge gaps in plant immunity Land plants include angiosperms, bryophytes, lycophytes and ferns, each of which may deploy distinct strategies to resist pathogens. Here, we investigate fern-pathogen interactions by characterizing n...

We got a message from the university to remove any use of the "DEI", "diversity", "equity", or "inclusion" from all public-facing documents. They said that even "biodiversity" is being flagged by the federal government. We live in the dumbest timeline.
