FAD2 — Glycine max

Summary

GLYMA_15G195201V4 (GmFAD2) on soybean chromosome 15 encodes a fatty acid desaturase with delta12 fatty acid acetylenase, oleate D12-hydroxylase, omega-6 and omega-3 fatty acid desaturase activities, and monooxygenase and oxidoreductase functions. The product localizes to the ER membrane and is associated with unsaturated fatty acid and triglyceride anabolism, fatty acid metabolism, lipid storage and localization, pigmentation, nitrogen fixation, sucrose metabolism, siRNA-mediated PTGS, homologous recombination, and regeneration. The gene has been connected to seed traits including linoleic acid, alpha-linolenic acid, protein content, weight, size, and viability, as well as xanthophyll content, water use efficiency, stomatal resistance, temperature stress responses, aphid response, disease tolerance, and salt tolerance. Studies of related genes in other species link the family to oleic acid content, fatty acid composition, aphid resistance, and salt tolerance.
