ANS — Solanum tuberosum

Summary

StANS (PGSC0003DMG400019119) on potato chromosome 10 encodes a 2-oxoglutarate-dependent dioxygenase with jasmonic acid hydrolase, leucocyanidin oxygenase, and flavonol synthase activities. The gene is associated with anthocyanin, flavonoid, coumarin, and morphine anabolism, as well as pigmentation and secondary metabolism. It is linked to the regulation of jasmonic acid-mediated signaling, downregulation of defense response to insect, defense response, and response to molecules of fungal origin and toxic substances. StANS has been associated with starch content, photosynthetic rate, anthocyanin content, drought stress tolerance, spider mite resistance, oxidative stress, and biotic stress tolerance. It localizes to the cytosol and cytoplasm. Studies of related genes in other species link the family to jasmonic acid response and disease resistance.
