FAD7 — Glycine max

Summary

GmFAD7 (GLYMA_03G056700V4) on soybean chromosome 3 encodes a fatty acid desaturase with omega-3 and omega-6 fatty acid desaturase activity, functioning as an acyl-lipid omega-3 desaturase (cytochrome b5) and linolenate delta15 desaturase. The product localizes to plastid, chloroplast, and ER membranes. This gene is associated with unsaturated fatty acid and carotenoid anabolism, fatty acid metabolism, seed germination, leaf development, and responses to cold and thermal stimuli. It has been connected to relative chlorophyll content, jasmonic acid content, stomatal resistance, and responses to aphids, drought, salt tolerance, temperature stress, and disease. Associations include altered fatty acid composition, aphid resistance, chilling sensitivity, trienoic fatty acid composition, pathogen defense, flower development, and water use efficiency. Studies of related genes in other species link the family to defense response, cold tolerance, wound response, systemic acquired resistance, and aphid resistance.
