| description | LEA (late embryogenesis abundant) proteins were first identified in land plants. Plant LEA proteins have been found to accumulate to high levels during the last stage of seed formation (when a natural desiccation of the seed tissues takes place) and during periods of water deficit in vegetative organs. Later, LEA homologues have also been found in various species [, ]. They have been classified into several subgroups in Pfam and according to Bray and Dure [].Dehydrin has been classified as part of the LEA family (D-11 from Dure, or group 2 from Bray) []. 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 notablefeatures is the presence, in their central region, of a continuous run offive to nine serines followed by a cluster of charged residues. Such a regionhas been found in all known dehydrins so far with the exception of peadehydrins. A second conserved feature is the presence of two copies of alysine-rich octapeptide; the first copy is located just after the clusterof charged residues that follows the poly-serine region and the second copyis found at the C-terminal extremity. |
