Metabolic enzymes moonlight as selective autophagy receptors to protect plants against viral-induced cellular damage

This study shows that metabolic enzymes act as autophagy receptors in plants to degrade defense executors during viral infection, revealing autophagy as a tolerance pathway rather than an antiviral defense.

ATG8ylation of vacuolar membrane protects plants against cell wall damage

This study identifies a vacuolar quality control pathway in plants that uses ATG8ylation to protect vacuolar integrity following cell wall damage.

A RabGAP-Rab GTPase pair regulates plant autophagy and immunity

This study identifies Rab3GAPL as a regulator of plant autophagy and immunity by modulating Rab8a and ATG8 interactions.

Plant autophagosomes mature into amphisomes prior to their delivery to the central vacuole

The paper identifies CFS1 as an autophagy adaptor that connects autophagosomes with the ESCRT-I component VPS23 to form amphisomes, facilitating vacuolar delivery in plants.

The Arabidopsis F-box protein FBW2 degrades AGO1 to avoid spurious loading of illegitimate small RNA

This study shows that FBW2 degrades AGO1 to prevent off-target RNA silencing by avoiding illegitimate small RNA loading.

Molecular features of RNA silencing against phloem-restricted polerovirus TuYV enable amplification of silencing signal from host transcripts

The paper investigates RNA silencing against TuYV in Arabidopsis, revealing 22-nt vsiRNA production by DCL2 and AGO1 stabilization despite viral suppression.

A cross-kingdom conserved ER-phagy receptor maintains endoplasmic reticulum homeostasis during stress

The paper identifies C53 as a conserved ER-phagy receptor that links autophagy with ribosome-associated quality control during ER stress in plants and mammals.

Immunocapture of dsRNA-bound proteins provides insight into tobacco rattle virus replication complexes and reveals Arabidopsis DRB2 to be a wide-spectrum antiviral effector

This paper uses immunocapture of dsRNA-bound proteins to identify Arabidopsis DRB2 as a wide-spectrum antiviral effector against multiple plant RNA viruses.
