Elucidation of the first committed step in betalain biosynthesis enables the heterologous engineering of betalain pigments in plants [PDF]

New Phytologist, 2015
Summary Betalains are tyrosine‐derived red‐violet and yellow pigments, found in plants only of the Caryophyllales order. Although much progress has been made in recent years in the understanding of the betalain biosynthetic process, many questions remain open with regards to several of the proposed steps in the pathway.

Post-transcriptional gene silencing of CYP76AD controls betalain biosynthesis in bracts of bougainvillea [PDF]

Journal of Experimental Botany, 2021
Abstract Betalain is one of four major plant pigments and shares some features with anthocyanin; however, no plant has been found to biosynthesize both pigments. Previous studies have reported that anthocyanin biosynthesis in some plants is regulated by post-transcriptional gene-silencing (PTGS), but the importance of PTGS in betalain ...

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 ...

First Betalain-Producing Bacteria Break the Exclusive Presence of the Pigments in the Plant Kingdom [PDF]

mBio, 2019
The biosynthesis of antioxidant pigments, namely, betalains, was believed to be restricted to Caryophyllales plants. This paper changes this paradigm, and enzyme mining from bacterial hosts promoted the discovery of bacterial cultures producing betalains.

Tyrosine Hydroxylation in Betalain Pigment Biosynthesis Is Performed by Cytochrome P450 Enzymes in Beets (Beta vulgaris). [PDF]

PLoS ONE, 2016
Yellow and red-violet betalain plant pigments are restricted to several families in the order Caryophyllales, where betacyanins play analogous biological roles to anthocyanins. The initial step in betalain biosynthesis is the hydroxylation of tyrosine to

Allelic differences in the key genes of betalain biosynthesis in table beet accessions with contrasting root color from the VIR collection

Труды по прикладной ботанике, генетике и селекции
Background. Table beet (Beta vulgaris L.) contains a great amount of naturally red-colored betanins. A number of enterprises are forced to import foreign dyes because the reserves of domestic plant raw materials are insufficient.

Enzymes and genes involved in the betalain biosynthesis in higher plants

African Journal of Biotechnology, 2011
Betalains, a class of water-soluble nitrogen-containing pigments, replace anthocyanins and serve the analogous functions in 13 families of the order, caryophyllales. They modulate the attractive appearance of plants and protect them against destructive oxidative damage.
