Abstract

The application discloses OsICMEL2 The application discloses application of a gene in improving cold tolerance of rice seedlings and buds simultaneously. The application provides application of a protein OsICMEL2 or a related biological material thereof in A1) or A2) as follows: A1) regulating cold tolerance of plants; and A2) cultivating plants with cold tolerance. The application is found by a method of genetic engineering OsICMEL2 The application regulates cold tolerance of rice seedlings and buds, and a method for regulating cold tolerance of rice in two periods can be obtained by using the gene, the understanding of the regulation of cold tolerance of rice is expanded, and the method has important significance for cultivating rice varieties with cold tolerance.
