ANS — Asparagus officinalis

Summary

AoANS (A4U43_C05F5240) on asparagus chromosome 5 encodes an isopenicillin N synthase-like Fe(2+) 2-oxoglutarate dioxygenase domain-containing protein with jasmonic acid hydrolase activity. The gene is associated with regulation of jasmonic acid-mediated signaling, downregulation of defense responses to insects, and regulation of defense responses to fungi. It has been linked to anthocyanin content, photosynthetic rate, and cellular responses to toxic substances. The gene is associated with drought stress tolerance, biotic stress tolerance, spider mite resistance, and antifungal resistance. Studies of related genes in other species link the family to jasmonic acid response and disease resistance. Additional associations include oxidative stress, polycyclic aromatic hydrocarbon sensitivity, and PAH detoxification. The protein localizes to the cytosol and cytoplasm.
