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 ...

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 ...

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.

Transcriptomic analysis reveals key genes related to betalain biosynthesis in pulp coloration of Hylocereus polyrhizus

Frontiers in Plant Science, 2016
Betalains have high nutritional value and bioactivities. Red pulp pitaya (Hylocereus polyrhizus) is the only fruit containing abundant betalains for consumer.

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.

Identification, expression analysis of quinoa betalain biosynthesis genes and their role in seed germination and cold stress

Plant Signaling & Behavior, 2023
Betalains provide Chenopodium quinoa bright color, and the key enzyme genes for betalain biosynthesis include CYP76AD, DODA, and GTs. In this study, 59 CqCYP76AD, CqDODA and CqGTs genes in quinoa were identified and characterized by gene structural ...

Effect of pH Changes on Antioxidant Capacity and the Content of Betalain Pigments During the Heating of a Solution of Red Beet Betalains

Polish Journal of Food and Nutrition Sciences, 2017
Red beets and their products are mainly consumed after processing. In this study, the effect of pH on changes in antioxidant capacity (AC) and the content of betalain pigments were analysed during the heating of a betalain preparation solution.

MycoRed: Betalain pigments enable in vivo real-time visualisation of arbuscular mycorrhizal colonisation.

PLoS Biology, 2021
Arbuscular mycorrhiza (AM) are mutualistic interactions formed between soil fungi and plant roots. AM symbiosis is a fundamental and widespread trait in plants with the potential to sustainably enhance future crop yields.
