Latest Patents
Zhongnan Yang's latest inventions include two notable patents:
1. **Plant thermo-sensitive male sterile mutant tms15 and uses thereof** - This invention reveals a new gene mutant, tms15, identified through EMS mutagenesis of Zhonghua 11. It demonstrates a male sterile phenotype under high temperatures (>28°C), while fertility can be restored under lower temperatures (22-24°C). The study indicates excessive proliferation of sporogenous cells and abnormal vacuolization of tapetum cells at elevated temperatures, with improvements observed after low temperature treatment.
2. **Rice thermo-sensitive male sterile gene mutant tms18 and uses thereof** - This patent describes the discovery of the tms18 mutant, whose fertility varies with temperature. The research highlighted the connection between fertility changes and the pollen outer wall's structural integrity. The unique sensitivity period of this mutant offers new theoretical foundations and practical applications for two-line hybrid rice breeding.
