ACC4 — Brassica oleracea var. botrytis

Summary

BoACC4, located on chromosome 4 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with 1-aminocyclopropane-1-carboxylate synthase activity, transaminase activity, pyridoxal phosphate binding, redox activity, ubiquitin-protein transferase activity, identical protein binding, and protein binding. The gene is associated with negative regulation of ethylene biosynthetic process, protein autoubiquitination, amino acid metabolic process, ethylene anabolism, fruit ripening, lateral root formation, ubiquitin-dependent proteolysis, protein ubiquitination, response to auxin, and defense response. BoACC4 is also linked to lateral root number, ethylene sensitivity, and salt stress tolerance. The protein localizes to the cytoplasm. Related genes in other species link the family to responses to wounding, IAA, ABA, darkness, ethylene, iron deficiency, and gravitropism, as well as lateral root initiation and flowering time.
