DLO1 — Daucus carota subsp. sativus
Summary
DCAR_017900, designated DcDLO1, encodes a 2-oxoglutarate/Fe(II)-dependent dioxygenase with salicylate 5-hydroxylase, flavone synthase and flavanone 3-dioxygenase activities. It is associated with salicylic acid breakdown, anthocyanin and flavonoid biosynthesis, and defence responses to oomycetes, fungi and bacteria. The gene has been linked to anthocyanin content, disease resistance, salicylic acid regulation, plant growth, leaf senescence and susceptibility to downy mildew, Phytophthora capsici and Pseudomonas syringae. It is also associated with cellular hypoxia and cold responses. Related genes in other species link the family to flavone biosynthesis and salicylic acid homeostasis, and to resistance to downy mildew, Botrytis cinerea and late blight.
