F3H — Brassica napus

Summary

BnF3H (DARMORV10_C08P26510.1) on chromosome C08 of oilseed rape encodes a 2-oxoglutarate-dependent dioxygenase with flavanone 3-dioxygenase, flavonol synthase and chalcone isomerase activities, belonging to the DIOX_N and IPNS-like Fe2OG oxygenase domain families. The gene is associated with flavonoid, anthocyanin, coumarin, lignin and phenylpropanoid metabolism, pigment accumulation and metabolism, seed development, responses to UV-B, auxin and fungal molecules, and localises to the cytosol, ER, tonoplast and nucleus. It has been linked to flower, petal and seed color, anthocyanin and lignin content, UV-B light sensitivity, oxidative stress response, respiration rate, root phototropism, stamen morphology, cold acclimation, circadian clock regulation, photosynthetic activity, lateral root development, genome stability, flagellin sensitivity, nematode resistance and seed coat pigmentation traits. Related genes in other species are linked to proanthocyanidin accumulation, UV-B tolerance and seed coat pigmentation.
