LEA — Brassica napus

Summary

BnLEA (DARMORV10_A09P58210.1) on chromosome A09 of oilseed rape encodes a dehydrin family protein with a dehydrin conserved domain and metal-binding molecular function. This gene is associated with the acquisition of desiccation tolerance, cellular responses to drought, salt, light stimulus, and desiccation, as well as protein denaturation, methylglyoxal anabolism, RNA anabolism, sulfur amino acid metabolism, pollen-stigma interaction, ascorbate metabolism, chlorophyll metabolism, the pentose-phosphate shunt, mitochondrial biogenesis, virus-induced PTGS, and regeneration. It is linked to net photosynthetic rate, photosynthetic rate, seed weight, germination rate, water use efficiency, stomatal resistance, seed size, seed maturation, root length, drought tolerance, and seedling establishment. The protein localises to the cytosol, cytoplasm, and nucleus. Studies of related genes in other species connect the family to harvest index and seedling growth traits.
