Regulation Mechanism of Plant Pigments Biosynthesis: Anthocyanins, Carotenoids, and Betalains
Anthocyanins, carotenoids, and betalains are known as the three major pigments in the plant kingdom. Anthocyanins are flavonoids derived from the phenylpropanoid pathway. They undergo acylation and glycosylation in the cytoplasm to produce anthocyanin derivatives and deposits in the cytoplasm. Anthocyanin biosynthesis is regulated by the MBW (comprised

The evidence for anthocyanins in the betalain-pigmented genus Hylocereus is weak
Here we respond to Zhou (BMC Genomics 21:734, 2020) “Combined Transcriptome and Metabolome analysis of Pitaya fruit unveiled the mechanisms underlying peel and pulp color formation” published in BMC Genomics.

Amaranth plants contain abundant betalains and flavonoids. Anthocyanins are important flavonoids; however, they cannot coexist in the same plant with betalains. Blue light influences metabolite synthesis and hypocotyl elongation; accordingly, analyses of

Diverting tyrosine: Data from untargeted metabolic analysis of tomato fruit accumulating L-DOPA
L-DOPA, also known as Levodopa or L-3,4-dihydroxyphenylalanine, is synthesised in plants from the amino acid tyrosine, through oxidation. Conversion of tyrosine to L-DOPA constitues the first step of betalain biosynthesis in plants.

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