Role of small molecule heat shock proteins in plants'response to high temperature stress
Small molecule heat shock proteins(sHSPs)are a type of functionally conserved proteins that do not de-pend on ATP and have molecular chaperone function.sHSPs are particularly important in the heat shock response of plants under high temperature stress.By preventing the thermal aggregation of error proteins and interacting with other heat shock proteins,sHSPs promoted the degradation or refolding of error proteins,thereby helped plants to respond to high tempera-tures.Besides,the expression of sHSP was regulated by heat shock elements,heat shock transcription factors,long non-coding RNA(lncRNA),micro RNA(miRNA)and some plant hormones.This article reviewed the gene structure,func-tion,regulatory mechanism and related research progress of plant sHSPs,focused on the response mechanism of plant sHSPs under high temperature stress,so as to provide a reference for studying the mechanism of plants'response to high temperature.
