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 ...

Betalain synthesis in alfalfa impacts fiber digestion and enteric methane production

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Betalain pigments, betacyanins, and betaxanthins are widely used as coloring agents as well as in pharmaceutical and functional foods. However, significant betacyanin production occurs in only a few species of plants, which limits their wider application.

Allelic differences in the key genes of betalain biosynthesis in table beet accessions with contrasting root color from the VIR collection

Труды по прикладной ботанике, генетике и селекции
Background. Table beet (Beta vulgaris L.) contains a great amount of naturally red-colored betanins. A number of enterprises are forced to import foreign dyes because the reserves of domestic plant raw materials are insufficient.
