FAD2 — Glycine max

Summary

GLYMA_03G144500V4 (GmFAD2) on soybean chromosome 3 encodes a fatty acid desaturase with delta12 fatty acid acetylenase, oleate D12-hydroxylase, and omega-6 fatty acid desaturase activities, among other oxidoreductase and monooxygenase functions. The gene is associated with unsaturated fatty acid and triglyceride anabolism, lipid storage and localization, pigmentation, and siRNA-mediated post-transcriptional gene silencing. It has been linked to seed traits including linoleic, alpha-linolenic, and palmitic acid content, seed weight, size, viability, and coat color, as well as stress responses to temperature, drought, and salinity, water use efficiency, stomatal resistance, disease tolerance, and aphid response. The encoded protein localizes to the endoplasmic reticulum membrane. Related genes in other species are associated with oleic acid content, fatty acid composition, and salt tolerance.
