ACO — Solanum lycopersicum

Summary

SOLYC02G081190.4, the tomato ACO gene on chromosome 2, encodes an ACC oxidase, a 2-oxoglutarate-dependent dioxygenase that requires vitamin C and metal binding for its activity. The gene is associated with a wide range of biological processes, including ethylene metabolism, auxin breakdown, cell wall organization, carpel formation, and responses to ether. It has been linked to numerous agronomically important traits, such as fruit firmness, fruit color, fruit weight, fruit shape, and fruit size, as well as lycopene, carotene, carotenoid, anthocyanin, flavonoid, sugar, starch, and amino acid content. Additional associations include root weight, root number, lateral root number, root hair length, shoot dry weight, seed dormancy, seed maturation, stomatal resistance, turgor pressure, respiration rate, and relative growth rate.
