LEA — Nicotiana attenuata

Summary

A4A49_37501 (symbol LEA, preferred name ECP40) on chromosome 1 of coyote tobacco (Nicotiana attenuata) encodes a dehydrin family protein containing a dehydrin conserved sequence and is associated with metal binding. This gene is linked to responses to abscisic acid, ethylene, water, cold, hypoxia, and 1-aminocyclopropane-1-carboxylic acid, as well as to cold acclimation, the MAPK cascade, embryogenesis, morphogenesis, seedling development, cell death, and defence against fungi. It localises to the membrane, cytosol, cytoplasm, and nucleus. Associations include seed maturation, photosynthetic rate, freezing and cold tolerance, osmotic and drought stress responses, salt stress tolerance, membrane stability, and seedling establishment. Related genes in other species are linked to hydrogen peroxide accumulation, ABA sensitivity, and drought stress resistance.
