ANS — Capsicum annuum

Summary

T459_25505 (ANS) on pepper chromosome 10 encodes a 2-oxoglutarate-dependent dioxygenase with jasmonic acid hydrolase, leucocyanidin oxygenase, flavonol synthase and flavanone 3-dioxygenase activities, and belongs to the IPNS-like Fe2OG oxygenase family. The gene is associated with anthocyanin, flavonoid, coumarin and morphine biosynthesis, regulation of jasmonic acid signalling, defence responses to fungi, oomycetes and insects, and cellular responses to toxic substances. It has been linked to fruit colour, flavonoid and anthocyanin content, pollen fertility, photosynthetic rate, drought and oxidative stress tolerance, spider mite resistance, pattern-triggered immunity, and jasmonate catabolism. Studies of related genes in other species connect the family to jasmonic acid response and disease resistance.
