ARC1 — Brassica napus

Summary

BnARC1 (DARMORV10_A01P15250.1) on chromosome A01 of oilseed rape encodes a protein with AAA chloroplast protein-transporting ATPase, ATP-dependent peptidase, metalloendopeptidase, ATP hydrolase, metal binding, mRNA binding, Zn binding, ATP binding, and protein binding activities, and belongs to the peptidase M41 family. The gene is associated with self-incompatibility, pollen adhesion, pollen recognition, rejection of self pollen, pollen germination, pollen tube growth, and syngamy. It is also linked to plastid and chloroplast fission, chloroplast biogenesis, chloroplast division and size, chloroplast stroma protein import, photosynthesis light reaction, PSII-associated light-harvesting complex II catabolic process, mitochondrial protein processing, vesicle fusion, exocytosis, secretion, detoxification, and cellular localization. Associations with seedling development, embryo development and viability, plant growth, and chloroplast transcription and gene expression have been observed. The protein localizes to the Ycf2/FtsHi complex, M-AAA complex, chloroplast membranes, plastid, and mitochondria. Studies of related genes in other species link the family to chloroplast division and R-loop homeostasis.
