ODC — Nicotiana attenuata

Summary

A4A49_34686 (ODC) in coyote tobacco (Nicotiana attenuata) encodes an ornithine decarboxylase, a pyridoxal phosphate-dependent enzyme with ornithine and lysine decarboxylase activities and protein homodimerization activity. The gene is associated with polyamine, putrescine, spermine, tyramine, nicotine, alkaloid, and lignin anabolism, as well as primary and secondary metabolism, organogenesis, callus formation, regeneration, chewing response, virus-induced PTGS, G1 and S phases, and cytoplasmic localization. It has been linked to carotene content, heterosis, seed viability, callus induction, and leaf size. Studies of related genes in other species connect the family to fruit volume and quality, root development traits, disease tolerance, shelf life, nutritional value, meristematic activity, and sprouting.
