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.

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.

Blue-grained genes in wheat and application thereof

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. The provided gene and method for propagation and maintenance of the sterile line have important significance and application value for hybrid breeding in wheat.

Fertility restoration gene in wheat and uses thereof

The present invention provides a rice whole genome breeding chip and the application thereof. The rice whole genome breeding chip of the present invention is Rice60K, an SNP chip manufactured based on Infinium technique. Each chip can detect 24 samples simultaneously and contains 58,290 SNP sites. The marker sites have DNA sequences represented by SEQ ID NO.1-58290. The chip can be used in molecular marker fingerprint analysis of the rice variety resources, in genotype identification of the hybrid progeny population, in identification of the variety authenticity, in analysis and screening of the genetic background of the breeding materials, and in association analysis of the agronomic traits, having wide application prospects.
