摘　　要：全球变暖将会严重影响植物的正常生长发育,并造成全球农作物的大幅减产。在此大背景下农作物的抗热育种工作就显得尤为重要。温度形态建成是植物进化出的一种应答高温逆境的生长发育策略,它是指高等植物所发生的全部有利于适应非逆境高温的形态变化。温度形态建成分子机制的研究将为农作物抗热育种提供理论依据,从而大幅提高育种效率。生长素、油菜素内脂和赤霉素是参与调控温度形态建成的重要植物激素。综述了生长素和赤霉素参与调控温度形态建成的分子机制,并探讨了未来的应用方向。Global warming will seriously affect the normal growth and development of plants,and cause a sharp decline in global crop yields.In this context,the heat resistance breeding of crops is very important.Thermomorphogenesis is a growth strategy developed by higher plant in response to non-stress high temperature,which refers to all the morphological changes that are conducive to adaptation to non-adverse high temperatures in higher plants.The research on the molecular mechanism of temperature morphogenesis will provide theoretical basis for the breeding of heat-resistant crops,consequently greatly improving the breeding efficiency.Auxin,brassinosteroid and gibberellin are important plant hormones involved in the regulation of thermomorphogenesis.In this paper,the molecular mechanism of auxin,brassinosteroid and gibberellin in controlling thermomorphogenesis was reviewed,and the future applied research direction was also discussed.
