LEA — Brassica oleracea

Summary

BoLEA, the LEA gene on chromosome 8 of cabbage (Brassica oleracea), encodes a protein containing a dehydrin conserved sequence (Dehydrin_CS) and is annotated with lipid-binding activities, including phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding, as well as metal binding. The gene is associated with cellular responses to drought, salinity, cold acclimation, abscisic acid, and light stimulus, and with processes such as seed germination, embryogenesis, and virus-induced PTGS. It is linked to traits including photosynthetic rate, seed maturation, and root length, and to the phenotype of seedling establishment. The protein localises to the vesicle membrane, cytosol, cytoplasm, and nucleus. Studies of related genes in other species connect the family to harvest index, net photosynthetic rate, seed weight, germination rate, water use efficiency, stomatal resistance, seed size, seedling growth, and drought tolerance.
