CER1 — Brassica oleracea

Summary

BoCER1, encoded by the gene BOLC102_C08P064930.1 on cabbage chromosome 8, is a decarbonylase with iron-binding, redox, and heme-binding activities, belonging to the CER1-like and sterol desaturase-related families. It is associated with wax, alkane, cutin, and very-long-chain fatty acid biosynthesis, as well as aldehyde metabolism, cuticle development, pollen exine formation, anther development, leaf senescence, and responses to stress, wounding, and jasmonic acid. The gene is linked to traits including leaf color, photosynthetic rate, chlorophyll content, days to flowering, pollen fertility, male sterility, trichome morphology, root morphology, low temperature stress response, disease tolerance, and white-backed planthopper response. Phenotypic associations include cuticular wax production, epicuticular wax deposition, alkane synthesis, cuticle formation, drought tolerance, freezing tolerance, dehydration tolerance, pathogen resistance and susceptibility, and fertility. Studies of related genes in other species link the family to alkane biosynthesis, wax crystallization, and whitefly resistance.
