The external and internal structures of fruits from 95 taxa representing 27 Ranunculaceae genera of China were studied. The results show that Ranunculaceae could be divided into 4 groups based on the fruit types, epidermal surface, vascular bundle, mesocarp cell, and endocarp cell structures: Group 1: follicle or achene, branching or branching and anastomosing vascular bundles, mesocarp parench...
Plant defensins are recognized for their antifungal properties. However, a few type 1 defensins (PDF1s) were identified for their cellular zinc (Zn) tolerance properties after a study of the metal extremophile Arabidopsis halleri. In order to investigate whether different paralogues would display specialized functions, the A. halleri PDF1 family was characterized at the functional and genomic l...
Flower stalks of Pulsatilla cernua, an early spring herb in north temperate Asia, changed position from erect to pendulous and back to erect during 6-10 d anthesis. We tested three possible explanations for this movement. Our results showed that (1) this movement is unlikely to be a mechanism to attract pollinators or enhance pollen output, because no pollinator preference was observed between ...
Feulgen bands can be obtained at the sites of constitutive heterochromatin in the chromosomes of Anemone blanda, Fritillaria lanceolata and Scilla siberica, simply by means of a short or extended acid hydrolysis. Extended hydrolysis gives positive bands in A. blanda and F. lanceolata and negative bands in S. siberica. Short hydrolysis gives no bands in A. blanda and S. siberica but gives negati...
In this study, 23 oleanane-type triterpenoid saponins were isolated from a methanol extract of the roots of Pulsatilla koreana. The NF-κB inhibitory activity of the isolated compounds was measured in TNFα-treated HepG2 cells using a luciferase reporter system. Compounds 19-23 inhibited TNFα-stimulated NF-κB activation in a dose-dependent manner, with IC50 values ranging from 0.75-8.30 μM. Compo...
