FAD7 — Glycine max

Summary

GLYMA_18G202600V4, designated GmFAD7, encodes a fatty acid desaturase with omega-3 fatty acid desaturase and acyl-lipid omega-3 desaturase (cytochrome B5) activities. The gene is associated with unsaturated fatty acid anabolism, fatty acid metabolism, and lipid oxidation. It has been linked to the regulation of seed size, carotenoid anabolism, and saponin anabolism. The encoded protein localises to the plastid, chloroplast, and endoplasmic reticulum membranes. GmFAD7 is associated with numerous agronomically relevant traits, including seed size, leaf size, chlorophyll content, proline content, protein content, germination rate, transpiration rate, stomatal resistance, and responses to drought, high and low temperature stress, and disease. It is also connected to jasmonic acid content, aphid response, and altered fatty acid composition. Studies of related genes in other species link the family to defense response, wound response, cold tolerance, and systemic acquired resistance.
