FADS — Glycine max

Summary

GLYMA_20G111000V4, also known as GmFADS or GmFAD2B, encodes a fatty acid desaturase with omega-6 fatty acid desaturase, oleate D12-hydroxylase, and monooxygenase activities. This soybean gene on chromosome 20 is associated with regulation of seed development, unsaturated fatty acid and triglyceride anabolism, lipid storage and oxidation, starch anabolism, and sterol anabolism. It has been connected to multiple seed composition traits including linoleic, linolenic, oleic, and palmitic acid content, as well as seed weight, seed size, protein content, and seed coat color. Additional associations include plant height, chlorophyll content, transpiration rate, stomatal resistance, germination rate, proline content, and starch content. The encoded protein localizes to the ER membrane. Related genes in other species are linked to drought tolerance.
