Beta-TUBULIN， Beta-TUBULIN GENE AND APPLICATION OF GENE SEGMENT THEREOF

The invention provides a β- tubulin segment of a β-tubulin gene， and also provides an application of the segment in controlling plant diseases and/or enhancing plant disease resistance， inhibiting pathogenic fungal development and pathogenicity， and improving the drug sensitivity of pathogens to tubulin binding agents. The invention also provides an in-vitro interference preparation including βTubdsRNA segments of the above-mentioned β-tubulin gene， and an application of the in-vitro interference preparation in breeding a transgenic plant resistant variety. The RNA interference technology of the β-tubulin gene of the present invention has green and safe advantages of increasing the drug sensitivity of pathogenic fungi， reducing the level of drug resistance， interfering with pathogenicity， enhancing plant disease resistance， controlling a variety of plant diseases， improving the drug sensitivity to a chemical agent (carbendazim)， and prolonging the dsRNAs drug retention period by the carbendazim.
