Abstract
The application discloses application of OsMGD protein in regulating rice seedling stage alkali tolerance, and belongs to the technical field of genetic engineering breeding. The technical problem to be solved by the application is how to improve plant stress resistance, for example, how to improve rice alkali tolerance. To solve the above technical problem, the application provides application of a protein or a substance for regulating expression of a gene coding the protein or a substance for regulating activity or content of the protein, and the application can be application of the protein or the substance for regulating expression of the gene coding the protein or the substance for regulating activity or content of the protein in regulating plant stress resistance. The protein can be a protein with an amino acid sequence of SEQ ID No. 1. The application first discloses application of the OsMGD protein in regulating rice alkali tolerance, and regulating expression amount or activity of the OsMGD protein in rice plants can obtain rice with significantly changed alkali tolerance.
