Developing an Efficient System for Hybrid Rice Seed Production Using Partial Male Sterility.

Abstract excerpt

Efficient production of hybrid rice seeds requires male sterility systems to overcome the challenges of self-pollination. In this study, we identified male gametic transfer defect (GTrD)5 and GTrD9 as essential genes for the process of male gamete transmission in rice. Mutations in these genes cause partial male sterility by impairing pollen tube elongation, thereby reducing the fertilisation rate. Using...
