摘　　要：Photoperiod-and thermo-sensitive genic male sterile(P/TGMS)lines display male sterility under high-temperature/long-day light conditions and male fertility under low-temperature/short-day light conditions.P/TGMS lines are the fundamental basis for the two-line hybrid breeding,which has notably increased the yield potential and grain quality of rice cultivars.In this review,we focus on the research progress on photoperiod-and thermo-sensitive genic male sterility in plants.The essence of P/TGMS line is their ability to produce viable pollen under varying conditions.We overview the processes involved in anther and pollen development,as well as the molecular,cellular,and genetic mechanisms underlying P/TGMS in Arabidopsis,rice,and other crops.Slow development has been identified as a common mechanism of P/TGMS fertility restoration in both Arabidopsis and rice,while reactive oxygen species homeostasis has been implicated in rice P/TGMS.Furthermore,we discuss the prospective applications of P/TGMS and potential solutions to the challenges in this field.This review deepens the understanding of the mechanisms underlying P/TGMS and its utilization in two-line hybrid breeding across diverse crops.
