LEA — Oryza sativa Japonica

Summary

OS11G0454000, also known as RAB21, LEA, or OsDHN1, encodes a dehydrin family protein in rice (Oryza sativa Japonica) on chromosome 11. The product exhibits lipid binding activity, including phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding. This gene is associated with water stress response, abscisic acid anabolism, cold acclimation, salt response, and immune response. It has been linked to membrane breakdown, actin depolymerization, starch breakdown, and mycose metabolism. Localization evidence connects the protein to the vesicle membrane, cytosol, and nucleus. Associations with agronomically important traits include grain yield, spikelet sterility, pollen fertility, heat and cold tolerance, germination rate, photosynthetic rate, stomatal resistance, chlorophyll content, soluble protein, amino acid, sugar, proline, and anthocyanin content. Studies of related genes in other species link the family to drought tolerance, winter survival, and seed maturation.
