Abstract

The invention discloses verticillium wilt resistance related GhBZR1 protein of Gossypium.hirsutum as well as a coding gene and application of the protein. A nucleotide sequence of the protein is as shown in SEQ ID NO.1. The invention provides the protein coded by the verticillium wilt resistance related gene GhBZR1 of the Gossypium.hirsutum. The verticillium wilt resistance related gene GhBZR1 isobtained by cloning from leaves of a verticillium wilt infected Gossypium.hirsutum variety 86-1, and RT-PCR proves that the gene GhBZR1 has synergistic expression in the leaves and root systems underthe stress of Verticillium dahliae. Disease resistance evaluation of arabidopsis thaliana for transformation and overexpression of the gene proves that the gene can improve the Verticillium dahliae resistance of the verticillium wilt infected Gossypium.hirsutum variety, so that the gene can be used for improving genetic improvement of the verticillium wilt resistance of the Gossypium.hirsutum or genetic improvement of the verticillium wilt resistance of other Verticillium dahliae host crops.

Description

technical field

[0001] The invention relates to the field of molecular biology, in particular to the GhBZR1 protein related to Verticillium wilt resistance of upland cotton and its coding gene and application. Background technique

[0002] Cotton is an important economic crop and occupies an important position in the national economy. It is not only an important raw material for textile, chemical, pharmaceutical and national defense industries, but also an important export commodity. Among them, upland cotton (Gossypium. hirsutum) is the main planting species, accounting for more than 99% of the cotton area in my country. Verticillium wilt is one of the most important diseases in cotton production. It was introduced into my country in the 1930s, and began to spread and cause damage in some areas of China's cotton-producing provinces in the early 1950s after liberation. At the beginning, the damage in the main cotton-producing areas of our country increased year by year, and ...
