AFT — Brassica napus

Summary

BnAFT (DARMORV10_A08P21870.1) on chromosome A08 encodes a protein containing STI1/HOP_DP and ankyrin repeat domains, with annotated 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, wax and cutin biosynthesis, and cellular oxidant detoxification. It localizes to the plastid outer membrane, Toc complex, and TOC-TIC supercomplex. Associations with agronomic traits include photosynthetic rate, chlorophyll content, seed size, plant height, stem thickness, 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.
