Promoter of cotton surface receptor protein gene Gbvdr3 and application thereof

The invention relates to a promoter of cotton surface receptor protein gene Gbvdr3 and application thereof, belonging to the field of biotechnology. In the invention, a promoter pgbvdr-3 of sea island cotton verticillium wilt resistance related gene Gbvdr-3 is obtained by a genome walking method; and the PLACE software analysis indicates that the promoter contains many elements related to diseaseresistance, stress and light regulation. According to the GUS dyeing result, the GUS gene is mainly expressed in root, floral organ and seed and rarely expressed in pod, indicating that the promoter is a tissue-specificity promoter.
