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.
光温敏雄性不育（P/TGMS）系在高温/长日照条件下表现为雄性不育，在低温/短日照条件下表现为可育。P/TGMS系是两系杂交育种的基础，显著提高了水稻品种的产量潜力和稻米品质。在本综述中，我们聚焦于植物光温敏雄性不育的研究进展。P/TGMS系的本质是它们在不同条件下产生可育花粉的能力。我们概述了花药和花粉发育过程，以及拟南芥、水稻和其他作物中P/TGMS的分子、细胞和遗传机制。发育迟缓已被确定为拟南芥和水稻中P/TGMS育性恢复的共同机制，而活性氧稳态与水稻P/TGMS有关。此外，我们讨论了P/TGMS的潜在应用以及该领域面临挑战的潜在解决方案。本综述加深了对P/TGMS机制及其在不同作物两系杂交育种中应用的理解。
