Characterisation of betalain biosynthesis in Parakeelya flowers identifies the key biosynthetic gene DOD as belonging to an expanded LigB gene family that is conserved in betalain-producing species

Frontiers in Plant Science, 2015
Plant betalain pigments are intriguing because they are restricted to the Caryophyllales and are mutually exclusive with the more common anthocyanins. However, betalain biosynthesis is poorly understood compared to that of anthocyanins.

Pollinator, herbivore, and climatic selective pressures differ across a floral color transition zone. [PDF]

Am J Bot
Abstract Premise Spatial and temporal variations in climate and ecological interactions may underlie the origin and maintenance of floral color polymorphisms across a species range. Betalains are nitrogen‐containing, phylogenetically restricted pigments that, like the widespread and well‐studied anthocyanins and carotenoids, may attract pollinators ...

Enzymes and genes involved in the betalain biosynthesis in higher plants [PDF]

African Journal of Biotechnology, 2011

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

Recombinant production of amaranthin and other betalain variants with yeast cell factories [PDF]

Synthetic and Systems Biotechnology
Betalains are a class of natural pigments found in plants of the Caryophyllales order. Betanin is the dominant betalain on the food colour market, even though over 80 other variants are known.

Sucrose and light induced betalain biosynthesis in callus cultures of bougainvillea (Bougainvillea spp.)

The Indian Journal of Agricultural Sciences, 2020
An attempt was made to substantiate the optimum sucrose level and light conditions for biosynthesis of betalain pigments (betaxanthins and betacyaninins) from callus cultures of bougainvillea (Bougainvillea spp.).

Integrated of metabolome and transcriptome analysis reveals the effect of artificial light at night on Platanus orientalis L. [PDF]

BMC Plant Biology
Background Artificial light at night (ALAN) and its associated biological impacts have regularly been characterized as predominantly urban issues. ALAN delays the senescence of plane tree leaves in cities, resulting in the longer retention of green ...

Complex Biochemistry and Biotechnological Production of Betalains [PDF]

Food Technology and Biotechnology, 2011
The demand for natural food colourants is increasing because of public awareness of their health benefits. Betalains are nitrogen-containing plant pigments whose colours range from red-violet betacyanins to yellow betaxanthins.
