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).…
Phase separation determining meiotic interference-sensitive meiotic crossover formation
Plant Science Research WeeklyIn sexual reproduction, meiosis creates new combinations between homologs and diversifies the genetic information among gametes and progenies. Most meiotic crossovers (COs) are mediated by a group of ZMM factors, including HUMAN ENHANCER of INVASION-10 (HEI10), which is suggested to concentrate at CO…
