The invention discloses application of an epiregulatory factor gene in regulation of plant heat resistance. The epiregulatory factor gene (TaMET) is identified from a wheat genome for the first time. The gene is subjected to transient overexpression in wheat Fielder, and it is found that wheat can be more sensitive to heat expression. The homologous gene (OsMET) of the gene in rice is subjected to conservative structural domain analysis to find that the gene is an SAM dependent type methylated transferase gene, and the modification level of histone H3K27me3 can be influenced. Research finds that overexpression of the gene makes the plant more sensitive to heat, knockout of the gene can significantly improve the heat resistance of rice Nipponbare, that is, the gene belongs to a negative regulation factor of rice heat resistance, for example, deep analysis of a mechanism of the gene or a homologous gene thereof is beneficial to excavation of heat-resistant genes in rice and wheat.
