ACO2 — Brassica oleracea

Summary

BoACO2, located on chromosome 9 of cabbage (Brassica oleracea), encodes a protein with ACC oxidase activity, 2-oxoglutarate dioxygenase activity, copper and vitamin C binding, and a DIOX_N domain. This gene is associated with ethylene biosynthesis and metabolism, chlorophyll breakdown, fruit ripening, leaf senescence, seed germination, cold acclimation, and responses to fungal molecules, nitric oxide, and fatty acids. It has been linked to protein and lignin content, ethylene and brassinosteroid sensitivity, seed dormancy, and phenotypes including nitrogen deficiency and waterlogging stress responses, abnormal leaf venation, and reduced root length. The protein localises to the cytosol, nucleus, plasmodesma, endoplasmic reticulum, Golgi, plasma membrane, and stress granules. Studies of related genes in other species connect the family to iron acquisition, flood tolerance, apical hook development, and seed development.
