ACO3 — Solanum lycopersicum

Summary

SlACO3 (SOLYC09G089580.4) on tomato chromosome 9 encodes a 2-oxoglutarate-dependent dioxygenase with ACC oxidase activity. The gene is associated with ethylene sensitivity, fruit abscission, leaf abscission, and fruit firmness, as well as lycopene and carotenoid content, fruit color, and fruit shape. It has been linked to seed maturation, germination rate, plant height, chlorophyll content, and selenium content. Associations also include responses to ether, flooding, and fatty acids, along with cytokinin and hormone metabolism, the MEP pathway, flavonoid metabolism, and glycosaminoglycan breakdown. The protein is localized to the cytoplasm, nucleus, and extracellular space. Studies of related genes in other species connect the family to desacetoxyvindoline 4-hydroxylase and 1-aminocyclopropane-1-carboxylate oxidase-like activities.
