LEA — Nicotiana attenuata

Summary

A4A49_40056, designated NaLEA in coyote tobacco (Nicotiana attenuata, chromosome scaffold05710), encodes a dehydrin family protein characterized by a Dehydrin_CS domain. The product is associated with phosphatidylglycerol, phosphatidylserine, phosphatidate, phosphoinositide, and general lipid binding. NaLEA is linked to cellular responses to desiccation, salt, drought, water, light stimulus, hypoxia, ethylene, and 1-aminocyclopropane-1-carboxylic acid, as well as cold acclimation, MAPK cascade, embryogenesis, morphogenesis, seedling development, cell death, and regulation of gene expression. It localizes to the vesicle membrane, membrane, cytosol, cytoplasm, and nucleus. Associations include seed maturation, photosynthetic rate, freezing and cold tolerance, osmotic stress response, drought response, salt stress tolerance, membrane stability, and seedling establishment. Related genes in other species link the family to drought tolerance, ABA signaling, and low temperature response.
