By using 5’ RACE, full-length coding region (1 148 bp) of BDN1 gene was produced. It is a new member of the dehydrin gene family. Southern analysis indicated that BDN1 is present in the 6. crassifolia genome as a single-copy gene. Northern analysis revealed that its expression is inducible by drought and cold stresses as well as ABA application.展开更多
