aco — Cicer arietinum

Summary

LOC101500864 (symbol aco, also known as ACO5 or CaACO5) on chickpea chromosome 5 encodes a protein with ACC oxidase activity, 2-oxoglutarate dioxygenase activity, vitamin C binding, and metal binding. The encoded protein belongs to the DIOX_N and IPNS-like Fe2OG oxygenase families. In chickpea, this gene is associated with ethylene biosynthesis, chlorophyll metabolism, coumarin anabolism, fruit ripening, seed germination, leaf development, and cellular responses to fatty acids and fungal molecules. It is linked to flower color, seed coat color, drought tolerance, hyponastic leaf movement, and localizes to the cytoplasm. Studies of related genes in other species connect the family to proline content, seed weight and size, stomatal opening, root length, and salt tolerance.
