As a cool season crop, wheat (Triticum aestivum L.) has an optimal daytime growing temperature of 15 °C during the reproductive stage. With global climate change, heat stress is becoming increasingly severe constraint on production. In this review, we summarize recent progress in understanding molecular mechanisms tolerance wheat. We firstly describe impact morphology and physiology its potential effect agronomic traits. then review discoveries determining genetic factors affecting tolerance, including effects phytohormone signaling epigenetic regulation. Finally, discuss integrative strategies to improve by utilization existing germplasm modern cultivars, landraces related species.
