This invention discloses the application of the WAT1 gene in regulating the absorption and accumulation of sulfonylurea herbicides in plants. The invention found that knocking out the OsWAT1 gene in rice reduces the absorption and accumulation of bensulfuron-methyl, lowers the bensulfuron-methyl content in rice, and increases resistance to bensulfuron-methyl. Rice with the OsWAT1 gene knocked out also developed resistance to ethoxysulfuron and sulfadiazine. Furthermore, knocking out the NtWAT1 homolog of flue-cured tobacco K326, indoor resistance verification experiments showed that the tobacco mutant also acquired bensulfuron-methyl resistance, also achieved by reducing herbicide absorption and accumulation. This indicates that the WAT1 gene plays a role in regulating the absorption and accumulation of sulfonylurea herbicides in plants and can be used to create new plant varieties with resistance to sulfonylurea herbicides.
