CER1 — Brassica napus

Summary

BnCER1 (DARMORV10_A09P69380.1) on chromosome A09 encodes a protein with decarbonylase activity, iron binding, redox activity, and heme binding, belonging to the CER1-like_C, sterol desaturase-related, and fatty acid hydroxylase families. This gene is associated with wax metabolism, alkane and cutin anabolism, very-long-chain fatty acid anabolism, cuticle development, and aldehyde metabolism. It has been linked to traits including net photosynthetic rate, leaf color, plant male sterility, pollen fertility, days to flowering, stomatal resistance, transpiration rate, chlorophyll content, low temperature stress response, disease tolerance, root morphology, trichome morphology, and white-backed planthopper response. Phenotypic associations include cuticular wax biosynthesis, epicuticular wax deposition, alkane synthesis, freezing tolerance, dehydration tolerance, drought tolerance, pathogen resistance and susceptibility, and fertility. The protein localizes to the ER membrane, plastid, mitochondria, cytosol, and plasmalemma. Related genes in other species are linked to alkane biosynthesis, wax crystallization, and whitefly resistance.
