AFT — Brassica napus

Summary

BnAFT (DARMORV10_C03P80670.1) on chromosome C03 of oilseed rape encodes a protein with ankyrin repeat and STI1/HOP domains, annotated with multiple molecular functions including cytochrome-b5 reductase activity, glycolipid binding, chloroplast targeting sequence receptor activity, and transmembrane signaling receptor activity. The gene is associated with chloroplast localization and protein import, embryonic morphogenesis, response to abiotic stimulus, fatty acid elongation, very-long-chain fatty acid metabolism, cutin-based cuticle development, wax anabolism, and cellular oxidant detoxification. It localizes to the plastid outer membrane, Toc complex, and TOC-TIC supercomplex. Associations with agronomic traits include plant pigment content, chlorophyll content, net photosynthetic rate, seed size, plant height, stem thickness, leaf shape, linolenic acid content, and responses to high temperature and salt stress. Related genes in other species link the family to chloroplast protein targeting, chilling tolerance, and very-long-chain fatty acid content.
