Our work is out now! (www.science.org/doi/10.1126/...). We discover a selective autophagy pathway that protects plants from the mess caused by RNA viruses. Intrigued? Follow the spaghetti trail for a summary of our findings🧵-->
Selective autophagy fine-tunes plant immunity to promote cell survival during viral infection
RNA viruses co-opt host endomembranes to form replication complexes, often triggering cellular stress and immune responses. Here, we show that Arabidopsis thaliana activates selective autophagy to res...

New preprint! 🐛 Root-knot nematodes hijack root cells, turning them into feeding sites and making plants very sick. Using a cross-species scRNA-seq approach we mapped this process and show how this knowledge can be used to engineer resistant crops.🌱 A summary🧵 : www.biorxiv.org/content/10.1...
