DLO1 — Asparagus officinalis
Summary
A4U43_C01F16860 (DLO1, AoANS) on asparagus chromosome 1 encodes a 2-oxoglutarate-dependent dioxygenase with leucocyanidin oxygenase, flavone synthase, flavonol synthase, flavanone 3-dioxygenase and salicylate 5-hydroxylase activities. The gene is associated with anthocyanin and flavonoid anabolism, salicylic acid breakdown, coumarin anabolism, and defence responses to oomycetes, fungi and bacteria. It has been linked to disease resistance and susceptibility to downy mildew, Phytophthora capsici and Pseudomonas syringae, as well as to anthocyanin accumulation, leaf senescence, salicylic acid regulation and plant growth. The product localises to the cytoplasm and chloroplast. Studies of related genes in other species connect the family to flavone biosynthesis and resistance to Botrytis cinerea and late blight.
