Plant rheostat BAP2 determines the direction of ER stress tolerance mechanisms
Plant Science Research WeeklyWhen protein folding is disrupted by abiotic or biotic stresses, cells can experience ER stress. Sensors like inositol-requiring enzyme 1 (IRE1) detect this stress, triggering the unfolded protein response (UPR) pathway. UPR signaling activates genes that restore proteostasis and maintain cellular vitality.…

Chloroplast redox state changes mark cell-to-cell signalling in the hypersensitive response (New Phytol)
Plant Science Research WeeklyProgrammed cell death (PCD) plays roles in both developmental and environmental responses across plant species. During pathogen attack, the hypersensitive response can limit spread of infection by orchestrating an organised death of cells around the infection area. A recent study by Lukan et al. demonstrated…
