Jean Keller, PhD

Merci pour ce thread @societebotaniquedefrance.fr :-)

C'est faux. Les hépatiques sont des plantes terrestres qui appartiennent à la lignée des plantes non-vasculaires à laquelle appartiennent également les mousses ou les anthoceros. Les symbioses entre les algues et les champignons sont les lichens.

With @kellerjeanphd.bsky.social, @katharinamel1.bsky.social, @tatiana-vernie.bsky.social, @mbianc.bsky.social, and many other people (not in bsky, I think), and collaborators 😁.

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...

1/ It is my pleasure to share the latest preprint of the team: "Symbiotic diversification relies on an ancestral gene network in plants"

Here, we identified and functionally validated a novel master regulator of intracellular symbioses!

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...
The continuation of a long standing project started by @oswaldovaldesl.bsky.social in @jeanmichelane.bsky.social‘s lab. 1/7 🧵

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...

Excited to share my first (but not last) published research at @lrsv-toulouse.bsky.social. A THREAD … [1/9]

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.

Congratulations @puginiercamille.bsky.social!!! You did an exceptional job and demonstrated excellent human skills! I'm sure you will have a brilliant scientific career ;) it has been a pleasure and a honor to work with you!

What a good way to start 2025 🥳very happy to see this out and to have been part of the journey!

Delighted to present an updated version of our LysM-RLK/AM symbiosis story in Marchantia! @lrsv-toulouse.bsky.social www.biorxiv.org/content/10.1...

Happy to join if there is still room :) (evolutionary biologist working on evolution of functional traits in plants)
