Mutation in rice alters sterility temperature, offering new agricultural insights

Thermo-sensitive genic male sterility 5 (tms5) is a widely used thermo-sensitive genic male sterile (TGMS) line for two-line hybrid rice production. Critical sterility-inducing temperature (CSIT) acts as a key threshold of TGMS lines. However, there are a few reports on the regulatory mechanism controlling CSIT.
