| Type: | Family | Name: | Dehydrin |
| Description: | A number of proteins are produced by plants that experience water-stress. Water-stress takes place when the water available to a plant falls below acritical level. The plant hormone abscisic acid (ABA) appears to modulate the response of plant to water-stress. Proteins that are expressed during water-stress are called dehydrins [, ]. Dehydrins contribute to freezing stress tolerance in plants and it was suggested that this could be partly due to their protective effect on membranes [].Dehydrins share a number of structural features. One of the most notable features is the presence, in their central region, of a continuous run offive to nine serines followed by a cluster of charged residues. Such a region has been found in all known dehydrins so far with the exception of peadehydrins. A second conserved feature is the presence of two copies of a lysine-rich octapeptide; the first copy is located just after the clusterof charged residues that follows the poly-serine region and the second copy is found at the C-terminal extremity. | Short Name: | Dehydrin |
