Symbiotic diversification relies on an ancestral gene network in plants Symbioses have been fundamental to colonization of terrestrial ecosystems by plants and their evolution. Emergence of the ancient arbuscular mycorrhizal symbiosis was followed by the diversification o...

Mechanisms, Detection, and Impact of Horizontal Gene Transfer in Plant Functional Evolution Abstract. Horizontal gene transfers (HGT) have been observed across the tree of life. While their adaptive importance in bacteria is conspicuous, the occur

So excited to see our review on how to detect horizontal gene transfers and their impact on plant functional evolution finally published in @theplantcell.bsky.social!
Great teamwork between @lrsv-toulouse.bsky.social and LGDP-Perpignan 😎🥳🌱

Wonderful talk by Baptiste Castel @baptistebio.bsky.social on fern immune system here at @instmolplantsci.bsky.social Great to meet @jonathandgjones.bsky.social lab alumni in Edinburgh too!

As promised, @eveteyssier.bsky.social PhD defense starting now!

If you want to learn about her work, just check her last post!

Go go go Eve!

Latest paper from the lab @eveteyssier.bsky.social @malick-mbengue.bsky.social @melaniekrich.bsky.social @pierremarcdelaux.bsky.social et al. just out @pnas.org : 1) Plants have used LysM-RLK receptors for 450 million years to dialog with symbionts, and 2) CO/LCOs might not be that essential

Congratulations @eveteyssier.bsky.social !

Broad application of plant protein tagging with ALFA tag for nanobody-based imaging and biochemical approaches Epitope tags are broadly used for detecting, modifying or purifying proteins of interest, but their breadth of application is often rather poor. Recently, the rationally designed ALFA tag and its ALFA...
