BpCYP76AD15 is involved in betaxanthin biosynthesis in bougainvillea callus

Planta, 2023
BpCYP76AD15 is involved in betaxanthin biosynthesis in callus, but not in bracts, in bougainvillea. Bougainvillea (Bougainvillea peruviana) is a climbing tropical ornamental tree belonging to Nyctaginaceae. Pigments that are conferring colorful bracts in bougainvillea are betalains, and that conferring yellow color are betaxanthins. In general, for red-

Characterization of the monophenolase activity of tyrosinase on betaxanthins: the tyramine-betaxanthin/dopamine-betaxanthin pair

Planta, 2005
Tyrosinase or polyphenol oxidase (EC 1.14.18.1) is the key enzyme responsible for melanin biosynthesis and for the enzymatic browning of fruits and vegetables. Although the function of tyrosinase in the secondary metabolism of plants remains unclear, it has been proposed that the enzyme plays a role in the betalain biosynthetic pathway.

Production of yellow‐flowered gentian plants by genetic engineering of betaxanthin pigments

New Phytologist, 2023
Summary Genetic engineering of flower color provides biotechnological products such as blue carnations or roses by accumulating delphinidin‐based anthocyanins not naturally existing in these plant species. Betalains are another class of pigments that in plants are only synthesized in the order Caryophyllales.

Humilixanthin a new betaxanthin from Rivina humilis

Phytochemistry, 1987
Abstract A new betalain has been isolated from fruits of Rivina humilis and identified as the betaxanthin humilixanthin, the 5-hydroxynorvaline-immonium conjugate of betalamic acid. Its structure was elucidated and characterized by 1 H NMR spectroscopy, FAB mass and GC/MS spectrometry, UV/Vis absorption spectroscopy, high-performance liquid ...

Photocontrol of betaxanthin synthesis in Celosia plumosa seedlings

Phytochemistry, 1973
Abstract Light stimulates the betaxanthin accumulation in Celosia plumosa . The induction is partially reversed by far-red and inhibited by actinomycin D, puromycin, salicylaldoxime and 2,4-dinitrophenol, while 3-(3,4-dichlorophenyl)-1,1-dimethylurea has an inhibitory effect only when photosynthesis is operative.
