ACO1 — Pisum sativum

Summary

PsACO1 (PSAT1G050200) on garden pea chromosome 1LG6 encodes an ACC oxidase (EC 1.14.17.4) with 2-oxoglutarate dioxygenase activity, a member of the Fe(II)/2-oxoglutarate-dependent dioxygenase superfamily. The enzyme is associated with ethylene biosynthesis, fruit ripening, seed development and germination, geotropism, cell growth, nitrogen fixation, coumarin anabolism, and responses to nitric oxide, fatty acids, potassium starvation, and fungal molecules. It localises to the cytoplasm and is linked to respiration rate, ethylene sensitivity, salt stress tolerance, resistance to necrotrophic infection, and gravitropic response. Studies of related genes in other species connect the family to iron acquisition and deficiency response, lateral root development, and plant growth, as well as traits including drought tolerance, root length, and lignin, cellulose, cytokinin, and iron content.
