The evolution of betalain biosynthesis in Caryophyllales [PDF]
New Phytologist, 2019 SummaryWithin the angiosperm order Caryophyllales, an unusual class of pigments known as betalains can replace the otherwise ubiquitous anthocyanins. In contrast to the phenylalanine‐derived anthocyanins, betalains are tyrosine‐derived pigments which contain the chromophore betalamic acid. The origin of betalain pigments within Caryophyllales and their

Complex pigment evolution in the Caryophyllales
New Phytologist, 2011SummaryCarotenoids and flavonoids including anthocyanins are the predominant pigments in flowering plants, where they play important roles in pollination, seed dispersal, protection against stress and signalling. In certain families within the Pentapetalae order Caryophyllales, an unusual class of pigments, known as betalains, replaces the more common ...

Plastid phylogenomic insights into the evolution of Caryophyllales
Molecular Phylogenetics and Evolution, 2019The Caryophyllales includes 40 families and 12,500 species, representing a large and diverse clade of angiosperms. Collectively, members of the clade grow on all continents and in all terrestrial biomes and often occupy extreme habitats (e.g., xeric, salty).

Anthocyanin synthesis potential in betalain-producing Caryophyllales plants
Journal of Plant Research, 2021 AbstractAlthough anthocyanins are widely distributed in higher plants, betalains have replaced anthocyanins in most species of the order Caryophyllales. The accumulation of flavonols in Caryophyllales plants implies that the late step of anthocyanin biosynthesis from dihydroflavonols to anthocyanins may be blocked in Caryophyllales.

Transcriptional control of anthocyanin biosynthetic genes in the Caryophyllales [PDF]
Journal of Experimental Botany, 2007 Anthocyanins and betacyanins, two types of red pigment, have never been found to occur together in plants. Although anthocyanins are widely distributed in higher plants, betacyanins have replaced anthocyanins in the Caryophyllales. The accumulation of flavonols in the Caryophyllales suggests that the step(s) of anthocyanin biosynthesis from ...

Androecial evolution in Caryophyllales in light of a paraphyletic Molluginaceae
American Journal of Botany, 2013• Premise of the study: Caryophyllales are highly diverse in the structure of the perianth and androecium and show a mode of floral development unique in eudicots, reflecting the continuous interplay of gynoecium and perianth and their influence on position, number, and identity of the androecial whorls. The floral development of five species from four

The family Nyctaginaceae (Caryophyllales) in Sonora, Mexico
Phytotaxa, 2022The family Nyctaginaceae comprises 7 tribes, 31 genera and 300–405 species distributed in the tropics and other warm regions of the world, and in Mexico, it has been studied mainly in the central-southern zone of the country. The aim of this work is to report the genera and species of Nyctaginaceae found in Sonora.

Medullary bundles in Caryophyllales: form, function, and evolution
New Phytologist, 2023Summary The occurrence of conducting vascular tissue in the pith (CVTP) of tracheophytes is noteworthy. Medullary bundles, one of the remarkable examples of CVTP, evolved multiple times across angiosperms, notably in the Caryophyllales. Yet, information on the occurrence of medullary bundles is fragmented, hampering our understanding of their ...

Sterols of caryophyllales with emphasis on amaranthaceae
Phytochemistry, 1991Abstract Thirty species of Amaranthaceae representing 14 genera, were examined for sterol composition. The major sterols were spinasterol, 7-stigmastenol, sitosterol and stigmasterol. Although previous work with 2 genera and 11 species of Amaranthaceae revealed only species with dominant Δ 7 -sterols, the present work shows 19 species with dominant Δ

Flavonols and C-Glycosylflavonoids of the caryophyllales
Biochemical Systematics and Ecology, 1978Abstract A survey of 112 species of the Caryophyllales showed the presence of flavonols in all eleven families and of C -glycosylflavonoids in nine families, being absent from the Aizoaceae and Cactaceae. 18% of the species contained both classes of compound.
