Tragopogon buphthalmoides (DC.) Boiss, is widely used as a food additive with some imputed health effects in folk medicine of western Iran. Unfortunately, despite the prevalent medicinal uses of the plant, there are no reports on the toxic effects of T. buphthalmoides aerial parts. The present study evaluated the potential toxicity of dried hydroethanolic extract of the species in wistar rats. ...

In recent decades, the focus of science and industry has been concentrated on production of metalnanoparticles (NPs). In this study, the biosynthesis of silver NPs by using Tragopogon buphthalmoides(Tragopogon b.) plant was investigated. Various effective parameters on the synthesis such as pH, extractvolume, concentration of silver nitrate, temperature and reaction time were ...

Tragopogon comprises approximately 150 described species distributed throughout Eurasia from Ireland and the UK to India and China with a few species in North Africa. Most of the species diversity is found in Eastern Europe to Western Asia. Previous phylogenetic analyses identified several major clades, generally corresponding to recognized taxonomic sections, although relationships both among ...

UNLABELLED PREMISE OF THE STUDY Natural hybrids have formed in Pullman, Washington, United States between the recently formed allotetraploids Tragopogon miscellus and T. mirus. In addition to forming spontaneously, these hybrids are semifertile, propagating via achenes. Previous work indicated that the tetraploid hybrids have genetic contributions from three progenitor diploids: T. dubius, T...

We investigated concerted evolution of rRNA genes in multiple populations of Tragopogon mirus and T. miscellus, two allotetraploids that formed recurrently within the last 80 years following the introduction of three diploids (T. dubius, T. pratensis, and T. porrifolius) from Europe to North America. Using the earliest herbarium specimens of the allotetraploids (1949 and 1953) to represent the ...
