Abstract excerpt
High temperature is one of several major abiotic stresses that can cause substantial loss of crop yields. Heat shock proteins (HSPs) are key components of heat stress resistance. Mutation of FES1A, an auxiliary molecular chaperone of HSP70, leads to defective acquired thermotolerance. Autophagy is a positive regulator of basal thermotolerance and a negative regulator of heat stress memory, but its function in...
