Patents by Inventor Ligeng MA

Ligeng MA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11753650
    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.

  • Patent number: 11390877
    Abstract: The disclosure discloses blue-grained genes in wheat and use thereof, and belongs to the fields of plant molecular biology, biochemistry, genetics and plant breeding. The disclosure is capable of, through using differential expression analysis of blue-grained and white-grained wheat, obtaining four genes for controlling wheat blue-grained trait: two MYB family transcription factors and two bHLH family transcription factors, and providing a plant recombinant expression vector of the above genes and a method for controlling plant anthocyanin synthesis, and has important theoretical and practical significance to research a synthetic pathway of blue-grained wheat aleurone layer pigment, serve as a screening marker in a plant transformation process and improve a nutritional value of a plant.

  • Patent number: 11130967
    Abstract: A fertility restoration gene in wheat and uses thereof, belonging to the field of plant biotechnology, specifically relating to the cloning of a recessive nuclear male sterility gene and a promoter thereof, and uses thereof in hybrid breeding. The fertility restoration gene FRG1 was successfully cloned by flow cytometry and high-throughput sequencing. The FRG1 gene can completely restore the male fertility of a Lanzhou genic male sterile mutant or allelic mutants thereof, which lays a foundation for the construction of a new wheat hybrid breeding technology system, meanwhile, which provides more possibilities to solve the technical bottlenecks of “three lines” and “two lines” hybridization technology of wheat, such as unstable fertility of sterile lines, limited resources for hybrid variety, the complexity of seed production technology and the high cost of seed production.
