AFT — Brassica napus

Summary

BnAFT (AKR2A) on chromosome C07 of oilseed rape encodes a protein with multiple annotated molecular functions including cytochrome-b5 reductase activity, glycolipid binding, chloroplast targeting sequence receptor activity, and L-ascorbate peroxidase activity, among others. The gene is associated with chloroplast localization and protein import, particularly through the Toc complex and plastid outer membrane. It is linked to embryonic morphogenesis, response to abiotic stimulus, very-long-chain fatty acid metabolism, cuticle development, and wax biosynthesis. Agronomically, BnAFT is associated with plant pigment content, net photosynthetic rate, chlorophyll content, seed size, plant height, stem thickness, root morphology, linolenic acid content, and responses to high temperature and salt stress. Studies of related genes in other species link the family to chloroplast outer membrane protein targeting, very-long-chain fatty acid content, and chilling tolerance.
