Abstract
This entry represents Pfam LEA_1, or D-113 from Dure, or group 4 from Bray. Proteins in this entry include LEA6, LEA18 and LEA46 from Arabidopsis. They may play roles in the adaptive process to water deficit in higher plants [ 1 ].
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 [ 2 , 3 ]. They have been classified into several subgroups in Pfam and according to Bray and Dure [ 4 ].
