FAD7 — Glycine max

Summary

GLYMA_07G151300V4, designated GmFAD7, encodes an acyl-lipid omega-3 desaturase (cytochrome b5) with omega-6 and omega-3 fatty acid desaturase activities, placing it in the fatty acid desaturase family. The gene is associated with unsaturated fatty acid and carotenoid anabolism, response to thermal and cold stimuli, leaf development, and seed germination. Its product localizes to plastid, chloroplast, and ER membranes. GmFAD7 is associated with drought tolerance, disease tolerance, aphid response, chlorophyll content, stomatal resistance, jasmonic acid content, and responses to high and low temperature stress. Phenotypic associations include altered fatty acid composition, chilling sensitivity, pathogen resistance, flower development, and water use efficiency. Studies of related genes in other species connect the family to wound response, systemic acquired resistance, and aphid resistance.
