ACO — Pisum sativum

Summary

PsACO (PSAT5G084920) on garden pea chromosome 5LG3 encodes an ACC oxidase, a 2-oxoglutarate-dependent dioxygenase. The gene is associated with ethylene biosynthesis, fruit ripening, seed development and germination, abscission, cell growth, geotropism, nodulation, and responses to heat and fungal molecules. It is also linked to coumarin anabolism, syngamy, and cellular response to fatty acid. Localised to the cytoplasm, PsACO is associated with flower colour, seed coat colour, proline content, salt tolerance, and hyponastic leaf movement. Studies of related genes in other species link the family to seed weight, seed size, stomatal opening, root length, and drought tolerance.
