G2 — Sorghum bicolor

Summary

SORBI_3003G178500, also known as SbG2, encodes a protein with multiple enzyme activities including naringenin-chalcone synthase, acetoacetyl-CoA reductase, and 3-hydroxyacyl-CoA dehydratase, and belongs to the FAE1-type polyketide synthase family. The gene is associated with very-long-chain fatty acid and wax biosynthesis, cutin-based cuticle development, suberin biosynthesis, and trichome papilla formation. It has been linked to traits including drought tolerance, salt tolerance, disease tolerance, flowering time, root morphology, leaf vein morphology, plant male sterility, and high temperature stress response. Localization evidence connects the product to the endoplasmic reticulum membrane, fatty acid elongase complex, cell wall, and chloroplast membranes. Studies of related genes in other species link the family to cuticular wax production, pollen fertility, and very-long-chain fatty acid synthesis.
