ANS — Asparagus officinalis

Summary

AoANS (A4U43_C02F2660) on asparagus chromosome 2 encodes a 2-oxoglutarate/Fe(II)-dependent dioxygenase of the IPNS-like family, annotated with jasmonic acid hydrolase, flavonol synthase, and flavanone 3-dioxygenase activities. The gene is associated with regulation of jasmonic acid-mediated signaling, downregulation of defense responses to insects, defense responses to oomycetes and fungi, and anthocyanin, flavonoid, coumarin, and morphine biosynthesis. It is linked to anthocyanin content, photosynthetic rate, drought stress tolerance, spider mite resistance, antifungal resistance, pattern-triggered immunity, jasmonate catabolism, and oxidative stress. The product localizes to the cytosol and cytoplasm. Studies of related genes in other species connect the family to jasmonic acid response and disease resistance, while sequence similarity links extend associations to traits including plant width, flower color, carotenoid content, and net photosynthetic rate.
