The evidence for anthocyanins in the betalain-pigmented genus Hylocereus is weak

open access: yesBMC Genomics, 2022
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.

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

open access: yesAm 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 ...

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

open access: yesNew 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.

Comparative transcriptomic profiling in the pulp and peel of pitaya fruit uncovers the gene networks regulating pulp color formation

open access: yesFrontiers in Plant Science, 2022
Pitaya (genus Hylocereus) is a popular fruit. To develop pitaya fruit with greater marketability and high nutritional value, it is important to elucidate the roles of candidate genes and key metabolites that contribute to the coloration of the pitaya ...

Betalains in some species of the amaranthaceae family: A review [PDF]

open access: yes, 2018
Natural pigments are largely distributed in the plant kingdom. They belong to diverse groups, with distinct biochemical pathways. Betalains with colours that range from yellow to red-violet can de divided into two main subgroups: betaxanthins and ...

Betalain production is possible in anthocyanin-producing plant species given the presence of DOPA-dioxygenase and L-DOPA [PDF]

open access: yes, 2012
Background Carotenoids and anthocyanins are the predominant non-chlorophyll pigments in plants. However, certain families within the order Caryophyllales produce another class of pigments, the betalains, instead of anthocyanins.

“La Vie en Rose”: Biosynthesis, Sources, and Applications of Betalain Pigments [PDF]

open access: yesMolecular Plant, 2018
Betalains are tyrosine-derived red-violet and yellow pigments found exclusively in plants of the Caryophyllales order, which have drawn both scientific and economic interest. Nevertheless, research into betalain chemistry, biochemistry, and function has been limited as comparison with other major classes of plant pigments such as anthocyanins and ...

Comparative Transcriptomic Analysis of the Metabolism of Betalains and Flavonoids in Red Amaranth Hypocotyl under Blue Light and Dark Conditions

open access: yesMolecules, 2023
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

Lineage-specific gene radiations underlie the evolution of novel betalain pigmentation in Caryophyllales. [PDF]

open access: yes, 2015
Betalain pigments are unique to the Caryophyllales and structurally and biosynthetically distinct from anthocyanins. Two key enzymes within the betalain synthesis pathway have been identified: 4,5-dioxygenase (DODA) that catalyzes the formation of ...
