the genus ranunculus l., with a worldwide distribution, is the largest member of the ranunculaceae. here, nuclear ribosomal internal transcribed spacer (its) sequence data and chloroplast trnlf sequence data were used to analyze phylogenetic relationships among members of the annual and perennial (group praemorsa, group rhizomatosa, group grumosa and group non-grumosa) species of ranunculus...

Two high mountain plants Soldanella alpina (L.) and Ranunculus glacialis (L.) were transferred from their natural environment to two different growth conditions (22 degrees C and 6 degrees C) at low elevation in order to investigate the possibility of de-acclimation to light and cold and the importance of antioxidants and metabolite levels. The results were compared with the lowland crop plant ...

In the pre-alpine region of Europe numbers and sizes of populations of the clonal lake shore plant Ranunculus reptans have declined because of the regulation of lake water levels. We investigated genetic variation among and within 17 populations of different size (cover 1-10 000 m) in R. reptans with RAPD (random amplified polymorphic DNA) profiles. We sampled 127 rosettes in 14 populations at ...

The reconstruction of reticulate evolutionary histories in plants is still a major methodological challenge. Sequences of the ITS nrDNA are a popular marker to analyze hybrid relationships, but variation of this multicopy spacer region is affected by concerted evolution, high intraindividual polymorphism, and shifts in mode of reproduction. The relevance of changes in secondary structure is sti...

Flower species is one of the key determinants aesthetic and economic value floral products. This research study sought to evaluate whether consumer perceptions appeal monetary valuations arrangements change by substituting high-cost with low-cost similar appearance. In addition, researchers explored preferences for flower symmetry, which provides information assist designers in choosing using i...

The genus Ranunculus L., with a worldwide distribution, is the largest member of the Ranunculaceae. Here, nuclear ribosomal internal transcribed spacer (ITS) sequence data and chloroplast trnLF sequence data were used to analyze phylogenetic relationships among members of the annual and perennial (Group Praemorsa, Group Rhizomatosa, Group Grumosa and Group non-Grumosa) species of Ranunculus...

We studied fitness consequ ences of clonal integration in 27 genotypes of the stoloniferous herb Ranunculus replans in a spatially heterogeneous light environment. We grew 216 pairs of connected ramets (eight per genotype) with mother ramets in light and daughter ramets in shade, In half of the pairs we severed the stolon connection between the two ramets at the beginning of the experiment, Dur...
