One ARGONAUTE protein governs sexual reproduction in brown algae
Plant Science Research WeeklyAcross multicellular eukaryotes, ARGONAUTE (AGO) proteins are the core of RNA silencing, steering development, defense, and stress responses by biding small RNA guides to seek out genes for repression. In plants and animals, these functions are distributed across multiple AGO homologs that support a…
Heat stress promotes Arabidopsis AGO1 phase separation and association with stress granule components
Plant Science Research WeeklyA new article by Blagojevic, Baldrich, and Schiaffini et al. reveals that Arabidopsis ARGONAUTE1 (AGO1) protein, a pivotal agent in miRNA and siRNA-mediated gene silencing associated with the rough endoplasmic reticulum, dynamically localizes within stress granule components during heat stress (HS).…
