| abstract |
The invention discloses a rice grain shape gene SRN1, a protein and an application thereof, and relates to the technical field of plant genetic engineering. The present invention provides the rice grain shape and grain weight gene SRN1, the protein encoded by it, and the application of the above gene or protein in regulating plant grain shape and grain weight. The invention also discloses a plasmid containing the above-mentioned gene, a plant expression vector, a host cell and its application in regulating rice grain shape. The present invention further clarifies the genetic mechanism of grain shape and grain weight of rice by interpreting the function of SNR1 gene, and lays a foundation for improving rice yield. |
