It is my pleasure to share:
"Stepwise evolution of the developmental and symbiotic functions of DELLA in land plants"

Here we investigated the role of the single GRAS transcription factor DELLA in #MyMarchantia

CPK28 was already present in the first land plant, and presents a paradox: the Marchantia version can perfectly replace the Arabidopsis version for immunity, but does not seem to participate to immunity in Marchantia ...

A novel pathosystem between Aeschynomene evenia and Aphanomyces euteiches reveals new immune components in quantitative legume root-rot resistance. Legumes are pivotal for sustainable agriculture, yet their productivity is hindered by soilborne pathogens such as Aphanomyces euteiches . This study introduces Aeschynomene evenia as a novel model to...

🚨 New preprint alert! 🚨
Excited to share my first preprint from my PhD! 🎉
We introduce a novel Aeschynomene evenia – Aphanomyces euteiches pathosystem to explore links between quantitative resistance and symbiosis in legumes. 🌱🔬
