Transcriptomics-based identification and characterization of glucosyltransferases involved in betalain biosynthesis in Hylocereus megalanthus

Plant Physiology and Biochemistry, 2020
Pitaya (Hylocereus spp.) is the only commercial cultivation of fruit containing abundant betalains for consumer. Betalains are water-soluble nitrogen-containing pigments with high nutritional value and bioactivities. In this study, contents of betaxanthins and betacyanins were compared between 'Guanhuabai' (H. undatus) and 'Huanglong' (H.

Isolation and characterization of the betalain biosynthesis gene involved in hypocotyl pigmentation of the allotetraploid Chenopodium quinoa

Biochemical and Biophysical Research Communications, 2018
In quinoa seedlings, the pigment betalain accumulates in the hypocotyl. To isolate the genes involved in betalain biosynthesis in the hypocotyl, we performed ethyl methanesulfonate (EMS) mutagenesis on the CQ127 variety of quinoa seedlings. While putative amaranthin and celosianin II primarily accumulate in the hypocotyls, this process produced a green

Casting light on the pathway to betalain biosynthesis: A review

Environmental and Experimental Botany, 2021
Abstract The biosynthesis of pigments is crucial for plant life. Betalains are hydrosoluble pigments almost completely restricted to species of the core Caryophyllales and, within the fungal lineage, the Basidiomycetes. As important specialized metabolites, betalains have strong antioxidant properties, and may confer tolerance to a wide range of ...

Biosynthesis of betalains: yellow and violet plant pigments

Trends in Plant Science, 2013
Betalains are the yellow and violet pigments that substitute anthocyanins in plants belonging to the order Caryophyllales. These pigments have attracted much attention because of their bioactivities, which range from an antioxidant capacity to the chemoprevention of cancer.

On the Mechanism of Decarboxylation of Betanidine. A Contribution to the Interpretation of the Biosynthesis of Betalaines

Helvetica Chimica Acta, 1972
AbstractBei der Biogenese des Betanins (2) aus Dopa (1) wird die Carboxylgruppe der Aminosäure in die Carboxylgruppe‐C(19) umgewandelt. Dieser Schluss beruht auf einem Deuterierungsversuch, bei dem gezeigt wird, dass die Monodecarboxylierung von Betanidin (3) zu einem Verlust von C(19) führt und dass dabei die Doppelbindung C(17)C(18) nach C(14)C(15)

Betalain plant sources, biosynthesis, extraction, stability enhancement methods, bioactivity, and applications

Food Research International, 2022
Betalains are plant pigments with functional properties used mainly as food dyes. However, they have been shown to be unstable to different environmental factors. This paper provides a review of (1) Betalain plant sources within several plant families such as Amaranthaceae, Basellaceae, Cactaceae, Portulacaceae, and Nyctaginaceae, (2) The biosynthesis ...
