To survive in ever-changing environments,plants have to correspondingly alter their development in response to environmental cues or stresses.High temperature stress(or heat-stress,HS)is one of the major environmental impacts limiting plant growth.The accumulation of heat shock proteins(HSPs)is an essential strategy that plants adopted to avoid or alleviate HS damages.Our previous studies shown that the mRNA levels of various HSPs were markedly increased by hundreds folds under HS conditions.
