Defining Color Change in Pitaya: A Close Look at Betacyanin Synthesis Genes in Stenocereus queretaroensis

Frontiers in Sustainable Food Systems, 2021
Betalains are tyrosine-derived plant pigments present in several species of the Caryophyllales order. Betalains are classified in red betacyanins and yellow betaxanthins and are implicated in plant stress tolerance and visual attraction for pollinators ...

Regulation Mechanism of Plant Pigments Biosynthesis: Anthocyanins, Carotenoids, and Betalains

Metabolites, 2022
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

Biosynthesis of plant pigments: anthocyanins, betalains and carotenoids [PDF]

The Plant Journal, 2008
SummaryPlant compounds that are perceived by humans to have color are generally referred to as ‘pigments’. Their varied structures and colors have long fascinated chemists and biologists, who have examined their chemical and physical properties, their mode of synthesis, and their physiological and ecological roles.

Comparison of betalain compounds in two Beta vulgaris var. cicla and BvCYP76AD27 function identification in betalain biosynthesis

Plant Physiology and Biochemistry, 2023
Beta vulgaris var. cicla is an edible, ornamental and horticultural plant. However, the difference of components and contents of betalain in beets with different leaf color are not well understood. Here, the stress resistance and metabolites of two B. vulgaris var. cicla cultivars were determined.

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.

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

BMC 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.

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

Frontiers 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]

, 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]

, 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.

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

, 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 ...
