Abstract

The application discloses a wheat fertility-related gene TaMS7 and an application method thereof, and belongs to the field of biotechnology. By analyzing a genome-wide expression profile of wheat anthers at different development stages, we obtain the wheat fertility-related gene TaMS7, and regulate the fertility of a plant by adjusting expression of the gene to produce and maintain wheat male sterility lines and to prepare hybrid seeds, wherein the discovery of this gene has important theoretical and practical significance for establishing an efficient technology system of wheat hybrid seed production, and for studying wheat male sterility mechanism and heterosis.
