1/ It is my pleasure to share the latest preprint of the team: "Symbiotic diversification relies on an ancestral gene network in plants"
doi.org/10.1101/2025...
Here, we identified and functionally validated a novel master regulator of intracellular symbioses! A thread ...

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...

~12 years after we coined it EPP1 with
@oswaldovaldesl.bsky.social
one afternoon when we were postdoc with
@jeanmichelane.bsky.social
! Congrats
@melaniekrich.bsky.social
@tatiana-vernie.bsky.social
et al. for the hard work! EPP1 is the fourth member of the Common Symbiosis Pathway 🍄🌱!

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...

We’re thrilled to share our latest preprint! In this study we provide a mechanistic insight into how the protein EPP1 (first identified in Rose et al., 2012) functions in partnership with SYMRK.

EPP1 couples receptor activation to cytoplasmic signaling in root nodule symbiosis
Legume symbiosis with nitrogen-fixing bacteria is controlled by a cascade of signaling events leading to root nodule development. While plant cell-surface receptors initiate this process, the link bet...

Two papers to tell us more about mysterious EPP1, a protein required for symbiosis. Well done
@tatiana-vernie.bsky.social
and all co-authors.
