CAC2 — Brassica napus

Summary

BnCAC2 (CAC2) on chromosome C05 of oilseed rape (Brassica napus) encodes a protein with biotin carboxylase, acetyl-CoA carboxylase, and MCCC activities, and binds ATP, metals, and phosphorylated amino acids. The gene is associated with fatty acid biosynthesis, lipogenesis, malonyl-CoA anabolism, lipid metabolism, lipid homeostasis and storage, seed development, embryogenesis, pyruvate metabolism, L-leucine breakdown, brassinosteroid-mediated signalling, and regulation of metabolism. It has been linked to leaf area index, net photosynthetic rate, seed protein content, stomatal resistance, root morphology, plant growth and development, chloroplast development, oxidative stress tolerance, and cell proliferation. The product localises to mitochondria, chloroplast envelope and stroma, plastid, cytosol, Golgi, vacuole, apoplast, and plasmodesmata. Studies of related genes in other species connect the family to fatty acid synthesis and photosynthetic performance.
