In present research, the full-length cDNA and the genomic sequence of a novel cold-regulated gene, CsCOR1, were isolated from Camellia sinensis L. The deduced protein CsCOR1 contains a hydrophobic N-terminus as a signal peptide and a hydrophilic C-terminal domain that is rich in glycine, arginine and proline. Two internal repetitive tridecapeptide fragments (HSVTAGRGGYNRG) exist in the middle of the C-terminal domain and the two nucleotide sequences encoding them are identical. CsCOR1 was localized in the cell walls of transgenic-tobaccos via CsCOR1::GFP fusion approach. The expression of CsCOR1 in tea leaves was enhanced dramatically by both cold- and dehydration-stress. And overexpression of CsCOR1 in transgenic-tobaccos improved obviously the tolerance to salinity and dehydration.
