{{blockquote|They have been found in 44 plant families, but no essential metabolic function has been established for them. They are precursors of benzo[''c'']phenanthridine [[alkaloid]]s, which are the active principal ingredients of many [[medicinal plant]] extracts. CAs have been implicated to have a possible protective role against insect predators, injuries, and nitrogen detoxification. They have been shown to promote plant tissue growth, somatic [[embryogenesis]] from in vitro cultures, and flowering. CAs inhibit [[indole-3-acetic acid]] oxidation and enhance [[ethylene]] biosynthesis. They have also been shown to enhance synergistically various effects of [[gibberellin]]s.<ref>{{ cite journal |last1=Kuklin |first1=A. I. |last2=Conger |first2=B.
