DLO1 — Solanum tuberosum

Summary

PGSC0003DMG402011292 (StDLO1) on potato chromosome 10 encodes a 2-oxoglutarate-dependent dioxygenase with salicylate 5-hydroxylase, flavone synthase, leucocyanidin oxygenase, and flavanone 3-dioxygenase activities. The gene is associated with salicylic acid breakdown, regulation of signaling, and defense response to oomycetes. It is linked to resistance to Botrytis cinerea, disease resistance, and late blight resistance, as well as anthocyanin content and fruit color. Associations also include regulation of flavonoid, anthocyanin, coumarin, lignin, and phenylpropanoid anabolism, pigmentation, and plant growth. The encoded protein localizes to the cytoplasm and chloroplast. Studies of related genes in other species link the family to flavone biosynthesis and susceptibility to downy mildew and Pseudomonas syringae.
