Two antagonistic gene regulatory networks drive Arabidopsis root hair growth at low temperature linked to a low‐nutrient environment
Root hair (RH) cells can elongate to several hundred times their initial size, and are an ideal model system for investigating cell size control. Their development is influenced by both endogenous a.....

Last good news from 2024!
Our latest paper on TE-derived small RNAs is finally out! It reveals a beautiful buffering mechanism involving epigenetics, chromatin organization, and pathogen resistance. A great collaboration with @plantevolution.bsky.social, don’t miss it!
