ANS — Capsicum annuum

Summary

CaANS (T459_00408) on pepper chromosome 1 encodes a leucoanthocyanidin dioxygenase, a 2-oxoglutarate-dependent dioxygenase with oxidoreductase activity that acts on paired donors. The gene is associated with anthocyanin, proanthocyanidin, flavonoid, coumarin and pigment biosynthesis, as well as regulation of flavonoid and phenylpropanoid metabolism. It has been linked to fruit ripening, fruit color, fruit weight, pungency, anthocyanin content, flavonoid content, photosynthetic rate, pollen fertility, UV light sensitivity, and responses to wounding, jasmonic acid, fungal molecules, cold stress, and defense. The encoded protein localises to the cytosol and cytoplasm and is linked to vacuole development and organisation. Related genes in other species are associated with proanthocyanidin synthesis and seed pigmentation.
