MOC1 — Brassica oleracea

Summary

BoMOC1 (BOLC102_C03P033890.1) on cabbage chromosome 3 encodes a MOC1-like protein with a methyltransferase domain and SAM-dependent methyltransferase superfamily fold. The product exhibits Holliday junction binding, endodeoxyribonuclease RUS activity, metal binding, and DNA binding. It is associated with virus-induced post-transcriptional gene silencing, DNA recombination, chloroplast organization, and cell cycle processes, and localizes to the chloroplast nucleoid. The gene has been connected to tiller number. Related genes in other species have been associated with photochemical quenching, root morphology traits, albino phenotypes, decreased chloroplast DNA copy number, and seed development arrest before germination.
