Changes in ambient temperature influence crop fertility and production. Understanding of.how crops sense and respond to temperature is thus crucial for sustainable agriculture. The.thermosensitive genic male-sterile (TGMS) lines are widely used for hybrid rice breeding and.also provide a good system to investigate the mechanisms underlying temperature sensing.and responses in crops. Here, we show that OsMS1 is a histone binding protein, and its.natural allele OsMS1wenmin1 confers thermosensitive male sterility in rice. OsMS1 is primarily.localized in nuclei, while OsMS1wenmin1 is localized in nuclei and cytoplasm. Temperature.regulates the abundances of OsMS1 and OsMS1wenmin1 proteins. The high temperature.causes more reduction of OsMS1wenmin1 than OsMS1 in nuclei. OsMS1 associates with the.transcription factor TDR to regulate expression of downstream genes in a temperaturedependent manner. Thus, our findings uncover a thermosensitive mechanism that could be useful for hybrid crop breeding.
