ACBP — Brassica napus

Summary

BnACBP (DARMORV10_A02P11050.1) on chromosome A02 of oilseed rape encodes an acyl-CoA-binding protein containing ankyrin repeats and a FERM/acyl-CoA-binding domain. The gene product exhibits fatty-acyl-CoA binding, phospholipase D activity, glycerophospholipase activity, ubiquitin-protein transferase activity, and binds lead ions, phosphatidate, and PtdIns(4,5)P2. BnACBP is associated with seed oil content, seed maturation, seed dormancy, and seed longevity, as well as embryo development, seedling development, and leaf shaping. It is linked to fatty acid homeostasis, sterol homeostasis, lipogenesis, triglyceride anabolism, and lipid transport. The gene is associated with responses to lead, hypoxia, low temperature, salt, drought, and freezing stress, and with traits including seed quality, protein content, leaf chlorosis, and stomatal closure. Studies of related genes in other species link the family to oxidative stress tolerance, pathogen resistance, heavy metal tolerance, and embryogenesis.
