- Abstract
Osmotic stress-related genes were selected from an EST database constructed from 7 cDNA libraries from different tissues of the hot pepper. A full-length cDNA of Capsicum annuum dehydrin (Cadhu), a late embryogenesis abundant (lea) gene, was selected from the 5' single pass sequenced eDNA clones and sequenced. The deduced polypeptide has 87% identity with potato dehydrin CI7. but very little identity with the dehydrin genes of other organisms. It contains a serinetract (S-segment) and 3 conserved lysine-rich domains (K-segments). Southern blot analysis showed that 2 copies are present in the hot pepper genome. Cadhu was induced by osmotic stress in leaf tissues as well as by the application of abscisic acid. The RNA was most abundant in green fruit. The expression of several osmotic stress-related genes was examined and Cadhu proved to be the most abundantly expressed of these in response to osmotic stress.
