Cloning and characterization of SiDHN, a novel dehydrin gene from Saussurea involucrata Kar. et Kir. that enhances cold and drought tolerance in tobacco
The full-length of SiDHN cDNA consisted of 703 base pairs (bp). SiDHN cDNA transgenic tobacco plants resisted to freezing and drought stresses. SiDHN enhanced plant cold and drought resistance. SiDHN could be used to genetically improve plant tolerance to abiotic stresses.
