Heat shock transcription factor gene AtHSFA6a, coding protein, and applications thereof

The invention belongs to the plant molecular biology and transgenosis related technical fields, concretely relates to verification of high temperature resistant function of arabidopsis thaliana heat shock transcription factor gene AtHSFA6a, and provides applications of the gene in cultivation of high temperature resistant new varieties of plants. The model plant arabidopsis thaliana is employed as a material, the AtHSFA6a gene T-DNA is inserted into a homozygous mutant strain salk-045608, and the functions of the AtHSFA6a gene in the aspect of plant high temperature resistance are studied. Experiment results show that, the AtHSFA6a gene knockout mutant shows a sensitive phenotype under heat shock stress, and is significantly or highly significantly different from the wild type at aspects of physiological indices of root length, fresh weight of an overground part, conductivity, osmotic pressure, malondialdehyde content, SOD enzymatic activity and the like, which shows that the AtHSFA6a gene plays an important
