Abstract
The invention discloses a rice temperature sensitive male sterile gene mutant tms18 and its uses. During the study of TMS18 gene, the inventors found that the changing of fertility was related to the structural integrity of the second layer of pollen outer wall. The inventors accidentally found the thermo sensitive male sterile mutant tms18. The fertility of the mutant was affected by different temperatures and can be restored under low temperature treatment. More importantly, the fertility sensitive period of the mutant was different from that of other thermo sensitive male sterile genes. This unique feature of the gene can provide a new theoretical basis and apply value for two-line hybrid rice breeding.
