Embodiment Construction

[0039] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. The following examples are only used to illustrate and explain the present invention, but not to limit the technical solution of the present invention. The scope of the claimed protection of the present invention is specifically defined by the claims.

[0040] The pathogenicity-related gene of the cruciferous black rot fungus identified in the invention encodes a two-component regulatory system sensory protein histidine kinase, which can be used as a disease-resistant breeding target or a drug target to prevent and control plant diseases.

[0041] The gene (XC_3670 gene) encoding the sensory protein histidine kinase of the two-component regulatory system provided by the present invention is one of the following nucleotide sequences:

[0042] 1) DNA sequence of sequence 1 in the sequence listing;

[0043] 2) A DNA se...

Abstract

The invention provides an application of a pathogenic gene (XC_3670) related to xanthomonas campestris pathovar campestris in preventing and treating plant diseases, wherein a gene coding double-component regulating and controlling system can sense the protein histidine-kinase and influence the expression of hrp (hypothalamic regulatory peptides) genes. As a disease-resisting breeding target or medicinal target, the gene can be applied to preventing and treating the crucifer black rot disease.

Description

technical field [0001] The invention relates to the application of genes in the prevention and control of plant diseases, in particular to the application of a gene related to the pathogenicity of cruciferous black rot fungus in the prevention and control of plant diseases. Background technique [0002] Plant diseases have always been one of the main problems plaguing agricultural production. Plant diseases are mainly caused by viruses, bacteria, fungi and nematodes. The damage of pathogens to host crops leads to crop yield reduction or even failure, resulting in serious economic losses. According to statistics, crop yield reduction due to diseases is as high as 20% in the world every year. Therefore, research and development of environmentally friendly plant disease control methods is a concern of people. In-depth research on the pathogenic molecular mechanism of plant pathogens can provide a working basis for the design and development of new methods for plant disease c...
