A natural allele of OsMS1 responds to temperature changes and confers thermosensitive genic male sterility.

ABSTRACT: 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 OsMS1^wenmin1 confers thermosensitive male sterility in rice. OsMS1 is primarily localized in nuclei, while OsMS1^wenmin1 is localized in nuclei and cytoplasm. Temperature regulates the abundances of OsMS1 and OsMS1^wenmin1 proteins. The high temperature causes more reduction of OsMS1^wenmin1 th
