ECR — Brassica napus

Summary

BnECR (ECR, CER10, TSC13) on chromosome C08 of oilseed rape encodes a protein with acetoacetyl-CoA reductase, trans-2-enoyl-CoA reductase (NADPH), and 3-hydroxyacyl-CoA dehydratase activities, placing it in the very-long-chain fatty acid (VLCFA) elongation complex. The gene is associated with VLCFA metabolism, wax and suberin biosynthesis, cuticle development, and sphingolipid metabolism. It has been linked to oleic acid content, net photosynthetic rate, transpiration rate, stomatal resistance, drought and salt tolerance, root morphology traits including root mass density and thickness, plant male sterility, and cell cycle and elongation traits. Associations also include trichome branching, embryonic pattern specification, and response to water. Related genes in other species are linked to VLCFA biosynthesis, cuticular wax formation, pollen fertility, and root hair elongation.
