Abstract
The present invention provides a heat-resistance plant gene JAZ5a and use thereof. The inventors of the present invention isolated for the first time a heat resistance gene from the plant of Brassica spp., which can greatly improve the heat-resistance ability of the plant, especially in the bolting stage. The present invention further provides a protein encoded by said gene and its preparation method, vectors and host cells containing said gene, and a method for preparing a transgenic plant containing said gene.
Claims17
An isolated polynucleotide comprising the nucleotide sequence as set forth in SEQ ID NO:
- 2.
An expression vector comprising a polynucleotide selected from the group consisting of:
- (i) a polynucleotide comprising (a) a cDNA sequence encoding a heat-resistance protein comprising the amino acid sequence of SEQ ID NO:4 or a heat-resistance protein having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:4 or (b) a nucleotide sequence operably linked to a heterologous promoter and encoding a heat-resistance protein comprising the amino acid sequence of SEQ ID NO:4 or a heat-resistance protein having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:4;
- (ii) a polynucleotide comprising the nucleotide sequence as set forth in SEQ ID NO:
- 1 operably linked to a heterologous promoter or the nucleotide sequence as set forth in SEQ ID NO:
- 2;
- and
- (iii) a DNA polynucleotide complementary to the full-length of the cDNA sequence of (i).
