ACC4 — Brassica oleracea

Summary

BoACC4, the cabbage gene on chromosome 4, encodes a 1-aminocyclopropane-1-carboxylate synthase and also possesses transaminase, pyridoxal phosphate binding, redox, ubiquitin-protein transferase, and protein binding activities. It is associated with the negative regulation of ethylene biosynthesis, chlorophyll breakdown, fruit ripening, seed germination, lateral root formation, defense response, and response to auxin. The gene is linked to lateral root number, lignin content, ethylene sensitivity, seed dormancy, and salt tolerance. It is also connected to strigolactone signaling and auxin response. Studies of related genes in other species link the family to responses to wounding, IAA, ABA, ethylene, darkness, iron deficiency, and gravitropism, as well as lateral root initiation and flowering time.
