Integrated sRNAome and RNA-Seq analysis reveals miRNA effects on betalain biosynthesis in pitaya. [PDF]
BMC Plant Biol, 2020 Abstract Background: MicroRNAs (miRNAs) and their regulatory functions in anthocyanin, carotenoid, and chlorophyll accumulation have been extensively characterized in many plant species. However, the miRNA regulatory mechanism in betalain biosynthesis remains mostly unknown.

Anthocyanins and betalains in evolution: Why mutual exclusion remains the best-supported model. [PDF]
Plant Biol (Stuttg)Anthocyanins and betalains are plant pigments produced through different biosynthetic pathways and are generally considered mutually exclusive. We examine claims of their co‐occurrence, arguing that methodological flaws and data misinterpretation have led to unsupported reports, and offer recommendations for more rigorous future research.

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.

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.
