HEAT SHOCK TRANSCRIPTION FACTOR A1b regulates heat tolerance in wheat and Arabidopsis through OPR3 and jasmonate signaling pathway.

High temperature adversely affects plant growth and severely causes crop yield loss worldwide, especially for chimonophilous wheat (Triticum aestivum L.; Akter and Islam, 2017). Heat shock transcription factors (HSFs) and plant hormones play regulatory roles in plant responses to heat stress (Baniwal et al., 2004). In this study, we found that TaOPR3 contributes to heat tolerance in wheat probably via regulating JA level.
