G2 — Sorghum bicolor

Summary

SORBI_3010G108600, also known as SbG2, encodes a 3-ketoacyl-CoA synthase, a member of the FAE1-type polyketide synthase family with acetoacetyl-CoA reductase and trans-2-enoyl-CoA reductase activities. This sorghum gene on chromosome 10 is associated with very-long-chain fatty acid biosynthesis and elongation, cutin-based cuticle development, suberin biosynthesis, wax anabolism, and sphingolipid metabolism. It has been linked to traits including drought tolerance, salt tolerance, high temperature stress response, oxidative stress response, abscisic acid sensitivity, flowering time, plant male sterility, leaf vein morphology, root morphology, and disease tolerance. The encoded protein localizes to the endoplasmic reticulum membrane, fatty acid elongase complex, cell wall, chloroplast membranes, and mitochondria. Studies of related genes in other species connect the family to cuticular wax formation, pollen fertility, and root suberin biosynthesis.
