New paper from the Yasin Dagdas (@plantophagy.bsky.social) group, this time in @science.org, on how plant cells cope with viral infection and how selective autophagy delays cell death to give plants a chance to survive. Chapeau and congratulations to all the authors! www.science.org/doi/10.1126/...

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...
