“…Dopa feeding did not induce an accumulation of betaxanthins by Celosia . The same behaviour was observed for other species of the Amarantaceae family (particularly of the genera Gomphrena and Iresine ), however for some species of Portulacaceae , Chenopodiaceae and Aizoaceae , when dopa had been added to the apical stem parts with single flower buds or inflorescences, a higher accumulation of betaxanthins were observed [ 205 ].…”

Natural pigments are largely distributed in the plant kingdom. They belong to diverse groups, with distinct biochemical pathways. Betalains with colours that range from yellow to red-violet can de divided into two main subgroups: betaxanthins and betacyanins. These types of pigments are confined into 13 families of the order Caryophyllales and in some genera of higher fungi (Amanita muscaria, Hygrocybe and Hygrophorus). The Amaranthaceae family includes diverse genera in which betalains are present: Alternanthera, Amaranthus, Beta, Chenopodium, Celosia and Gomphrena. The biosynthesis of betalains and their general biological properties were reviwed in the present work. In addition, the types of betalains present in some species of the aforementioned genera, their stability and production, as well as biological attributes, were reviewed.

“…3c), II (tyrosine), III (glycine), vulgaxanthin I (glutamine), II (glutamic acid), dopaxanthin (3,4 -dihydroxyphenylalanine), miraxanthin I (methionine sulfoxide), indicaxanthin (proline), and humulixanthin (5-hydroxynorvaline) (Piattelli et al 1965;Adachi and Nakatsukasa 1983;Strack et al 1987;Böhm et al 1991;Trezzini and Zryd 1991). Free betalamic acid could be detected in P. grandiflora petals, especia1ly together with betaxanthins (Kimler et al 1971;Reznik 1978;Adachi and Nakatsukasa 1983), but its presence obviously depends on the genotype (Adachi and Nakatsukasa 1983;Böhm et al 1991;Rink and Böhm 1991). Betalain formation is preceded by an increase in tyrosine concentration in P. grandiflora flowers (Kishima et al 1991b).…”

“…It cannot be excluded that during this time vulgaxanthin II was first formed and then turned into vulgaxanthin I under the influence of an increasing amount of glutamine produced by GS. The exchange of the amino-acid moiety in betaxanthins is known from semisynthetic work (Rink and B€ ohm, 1991;Trezzini and Zryd, 1991), although under alkaline conditions which do not occur in whole plants. If this process would take place in the hairy roots, the discrepancy outlined in Section 1 would in fact not exist.…”
