LEA — Beta vulgaris subsp. vulgaris

Summary

BvLEA (BVRB_6G129380) on sugar beet chromosome 6 encodes a dehydrin family protein with a conserved dehydrin signature, capable of binding lipids including phosphatidylglycerol, phosphatidylserine, phosphatidate and phosphoinositides, as well as metals. The gene is associated with cellular responses to desiccation, salt, drought, cold acclimation, oxidative stress, light stimulus, and 1-aminocyclopropane-1-carboxylic acid, alongside processes such as embryogenesis, anthocyanin metabolism, DNA replication and cell cycle regulation. It localises to the vesicle membrane, membrane, cytosol, cytoplasm and nucleus. Associations include photosynthetic rate, freezing and cold stress tolerance, seedling establishment, drought and salt stress tolerance, osmotic stress response, membrane stability, and abscisic acid response. Studies of related genes in other species link the family to drought tolerance, salt tolerance, ABA sensitivity, and low temperature response.
