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). Because of their intracellular nature, the est...

Great story in collaboration with @pierremarcdelaux.bsky.social and @jeanmichelane.bsky.social groups. EPP1 story continues after many years of collaborations with Pierre-Marc and Jean-Michel!!!

I just published: Stop displaying journal names on your slides

A mentoring event at a Congress called for better support of early-career scientists - but what followed sent mixed signals. This blog reflects on those moments and ends with a pledge.

What will happen when we run out of phosphorous? 🥀

@hatem-rouached.bsky.social talks about ARSK1 & TORC1 interactions to regulate growth under P-deficiency #ICAR2025

Isidra-Arellano & @oswaldovaldesl.bsky.social provide insight into the influence of phosphate & iron uptake and homeostasis on root nodule symbiosis, and how this could be harnessed for more efficient nitrogen fixation in legume crops.
