Abstract: 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 respond to viruses targeting mitochondria, chloroplasts, and the endoplasmic reticulum. Rather than degrading viral components, autophagy selectively removes the immune regulator Enhanced Disease Susceptibility 1 (EDS1) to prevent cell death. This targeted mechanism is mediated by oligomeric metabolic enzymes that moonlight as selective autophagy receptors, linking organelle stress to immune homeostasis. Our findings establish selective autophagy as an essential immune rheostat, fine-tuning defense responses and safeguarding cellular integrity to promote host survival during viral infections.
