Casting light on the pathway to betalain biosynthesis: A review
Environmental and Experimental Botany, 2021Abstract 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, 2013Betalains 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.

Tyrosinase involved in betalain biosynthesis of higher plants
Planta, 1999A tyrosine-hydroxylating enzyme was partially purified from betacyanin-producing callus cultures of Portulaca grandiflora Hook. by using hydroxyapatite chromatography and gel filtration. It was characterized as a tyrosinase (EC 1.14.18.1 and EC 1.10.3.1) by inhibition experiments with copper-chelating agents and detection of concomitant o-diphenol ...

Critical Reviews in Food Science and Nutrition, 2000
Pigments are present in all living matter and provide attractive colors and play basic roles in the development of organisms. Human beings, like most animals, come in contact with their surroundings through color, and things can or cannot be acceptable based on their color characteristics.

Characterization of a tyrosinase from Amanita muscaria involved in betalain biosynthesis
Phytochemistry, 1996Abstract A tyrosinase was characterized from the betalain-containing pileus of the mushroom Amanita muscaria . The enzyme was located exclusively in the coloured parts of the mushroom and hydroxylated tyrosine to 3-(3,4-dihydroxyphenyl)-alanine (DOPA), suggesting that it is involved in betalain biosynthesis.

Biosynthesis and Regulation of Betalains in Red Beet
2012The red beet (Beta vulgaris) gets its distinctive color from betalains, one of the major plant pigment groups. Betalain-bearing plants appeared among plants of the families Caryophyllales, of which red beet is one of the main crops. Betalain pigments are classified into two groups—red betacyanin and yellow betaxanthin—and they all contain two atoms of ...

Betalain biosynthesis by red beet (Beta vulgaris L.) hairy root culture
Process Biochemistry, 2005The time course of growth and betalains biosynthesis by Beta vulgaris L. (cv. Detroit Dark Red) hairy root culture were investigated. It was established that hairy root culture produced 42.2 mg/flasks betalains (26.2 mg/flasks betaxanthins and 16.0 betacyanins) between 6th and 15th days of cultivation.

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.

Abstract Shoots of Disphyma australe, a coastal succulent plant native to New Zealand, vary in colour from entirely red to entirely green. We hypothesised that the red pigmentation develops in response to salinity stress, and that these betalain pigments contribute to salt tolerance. Effects of salinity on betalain content, CO2 assimilation, stomatal
