RAPE HEAT SHOCK PROTEIN GENE HSP17.8 AND USES THEREOF

摘要

A rape heat shock protein gene HSP17.8 and uses thereof are provided. Also provided are nucleotide sequence and amino acid sequence of the gene, gene sequences which have at least 70% homology with the DNA sequence as shown in SEQ ID NO:1 in other crops, and mutant alleles or derivatives thereof produced by adding, substituting, inserting or deleting one or more nucleotides. At the same time, it is proved that over expression of the heat shock protein strengthens the heat-tolerances of arabidopsis thaliana at high temperature by means of model plant, namely the arabidopsis thaliana, through transgenic technology, increases the yield of seeds at high temperature, and improves the yield of the arabidopsis thaliana under high temperature stress, so the heat shock protein gene has good application prospect in heat-tolerance breeding of crops.
