LEA — Brassica napus

Summary

BnLEA (LEA) on chromosome C08 of oilseed rape (Brassica napus) encodes a protein with a dehydrin conserved domain and exhibits phosphatidylglycerol, phosphatidylserine, phosphatidate, phosphoinositide, and lipid binding activities, along with metal binding. The gene is associated with acquisition of desiccation tolerance, cellular responses to drought, salinity, and light stimulus, protein denaturation, pollen-stigma interaction, chlorophyll metabolism, the pentose-phosphate shunt, meristem development, and regeneration. It is linked to traits including photosynthetic rate, seed weight, seed size, seed maturation, germination rate, water use efficiency, stomatal resistance, root length, drought tolerance, and 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, seedling growth, and seed production.
