Engineering Betalain Biosynthesis in Tomato for High Level Betanin Production in Fruits
Frontiers in Plant Science, 2021 Betalains are pigments found in plants of the Caryophyllales order, and include the red-purple betacyanins and the yellow-orange betaxanthins. The red pigment from red beets, betanin, is made from tyrosine by a biosynthetic pathway that consists of a ...

Pollinator, herbivore, and climatic selective pressures differ across a floral color transition zone
American Journal of Botany, Volume 113, Issue 1, January 2026.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 ...

Temperature-sensitive Responses of Red Light-dependent Betacyanin Synthesis [PDF]
Plant Physiology, 1979 Amaranthus tricolor half-seedlings show a greater accumulation of betacyanin in response to a defined period of red light if given a pretreatment at an elevated temperature (40 C). Red light given before the shift to 40 C is ineffective. The maximum response is achieved after a 2-hour shift to 40 C and if the red light is given 1 hour after return to ...
