BACKGROUND Artemisia frigida Willd. is an important Mongolian traditional medicinal plant with pharmacological functions of stanch and detumescence. However, there is little sequence and genomic information available for Artemisia frigida, which makes phylogenetic identification, evolutionary studies, and genetic improvement of its value very difficult. We report the complete chloroplast genome...

DOWNIE, S. R., and K. E. DENFORD. 1986. The flavonoids of Arnicafrigida and A. louiseana (Asteraceae). Can. J . Bot. 64: 2748-2752. Forty-six populations within the Arnicafrigida Meyer ex Iljin louiseana Farr complex were examined for flavonoid content. Seven glycosides were isolated and six identified. Members of this complex were found to produce primarily quercetin and kaempferol 3-O-glycosi...

Scrophularia ningpoensis has been used in China for centuries as a herbal tea to treat various diseases. Based on the numerous animal studies on its pharmaceutical effects and the long time clinical experiences, we studied the molecular and cellular mechanism underlying the bioactivity of aqueous extract of Scrophularia and its isolated compounds. Seven isolated compounds, unlike Scrophularia e...

Studies of natural genetic variation for the vernalization requirement in Arabidopsis have revealed two genes, FRIGIDA and FLOWERING LOCUS C (FLC), that are determinants of the vernalization-requiring, winter-annual habit. In this study, we show that FLOWERING LOCUS C EXPRESSOR-LIKE 4 (FLL4) is essential for upregulation of FLC in winter-annual Arabidopsis accessions and establishment of a vern...

Different studies describe the anti-inflammatory effects of Scrophularia species, a medicinal plant widely used in folk medicine since ancient times. As knowledge regarding the anti-neoplastic properties of this species is rather limited, we investigated the influence of methanol extracts of different Scrophularia species on cell proliferation, ce...

We quantitatively studied the hydration and dehydration behaviour of the three astrobiological model lichens Xanthoria elegans, Buellia frigida and Circinaria gyrosa by thermoanalysis and gravimetric isotherm measurements under close-to-Martian environmental conditions in terms of low temperature and low pressure. Additionally, the impact of UVC exposure on the isolated symbionts of B. frigida ...
