FAD2 — Glycine max

Summary

GLYMA_19G147400V4 (GmFAD2) encodes a fatty acid desaturase with delta12 fatty acid acetylenase, oleate D12-hydroxylase, and omega-6 fatty acid desaturase activities, localizing to the ER membrane. This soybean gene on chromosome 19 is associated with unsaturated fatty acid and triglyceride anabolism, fatty acid metabolism, lipid storage and localization, pigmentation, nitrogen fixation, and sucrose metabolism. It has been connected to seed traits including linoleic acid, alpha-linolenic acid, protein content, weight, size, and viability, as well as temperature stress responses, water use efficiency, stomatal resistance, aphid response, and disease tolerance. Related genes in other species are linked to oleate desaturation, fatty acid composition, salt tolerance, and aphid resistance.
