ANS — Solanum tuberosum

Summary

StANS (PGSC0003DMG400011929) on potato chromosome 3 encodes a 2-oxoglutarate/Fe(II)-dependent dioxygenase with jasmonic acid hydrolase activity, leucocyanidin oxygenase activity, and flavonol synthase activity. The gene is associated with anthocyanin, flavonoid, and secondary metabolite biosynthesis, as well as pigmentation and starch metabolism. StANS is linked to regulation of jasmonic acid-mediated signaling, downregulation of defense responses to insects, and defense responses to oomycetes. Associations with starch content, anthocyanin content, photosynthetic rate, drought stress tolerance, spider mite resistance, and antifungal resistance have been reported. The protein localizes to the cytosol and cytoplasm. Studies of related genes in other species link the family to jasmonic acid response and disease resistance, while sequence similarity connections extend to traits including flower color, fruit color, chlorophyll content, and net photosynthetic rate.
