FLS — Nicotiana attenuata

Summary

A4A49_43479 (FLS) in coyote tobacco (Nicotiana attenuata) encodes a non-haem dioxygenase N-terminal domain-containing protein with flavonol synthase activity, flavanone 3-dioxygenase activity, and 2-oxoglutarate dioxygenase activity, and is associated with vitamin C and metal binding. This gene is associated with flavonoid metabolism, flavonoid anabolism, anthocyanin anabolism, regulation of anthocyanin anabolism, proanthocyanidin anabolism, regulation of proanthocyanidin anabolism, coumarin anabolism, pigmentation, seed maturation, flower development, regulation of flower development, pistil development, pollen germination, pollen tube growth, post-transcriptional gene silencing, and response to molecules of fungal origin. Associations with flower color, flavonoid content, anthocyanin content, and root hair length are also noted. The protein is localized to the cytoplasm. Studies of related genes in other species link the family to flavonol synthase (EC 1.14.20.6) and naringenin 3-dioxygenase (EC 1.14.11.9) activities.
