A full-length 1.1 kb cDNA, designated Oryza sativa
Dehydrin 1 (OsDhn1), was isolated from the seed coat
of rice. The deduced protein is hydrophilic and has
three K-type and one S-type motifs (SK3-type), indicat-
ing that OsDhn1 belongs to the acidic dehydrin family,
which includes wheat WCOR410 and Arabidopsis
COR47. Expression of OsDhn1 was strongly induced
by low temperature as well as by drought. Induction of
OsDhn1 by cold stress was clearcut in the roots of
seedlings and the epidermis of palea and lemma.
