Phylogeny and quaternary history of the European montane/alpine endemicSoldanella(Primulaceae) based on ITS and AFLP variation
2001
Soldanella contains 16 species of herbaceous perennials that are endemic to the central and south European high mountains. The genus is ecogeographically subdivided into forest/montane and alpine species. Evolutionary relationships and large-scale biogeographic patterns were inferred from parsimony analyses of the internal transcribed spacer (ITS) regions of nuclear ribosomal DNA, and genetic distance analyses based on amplified fragment length polymorphism (AFLP) markers. The ITS region proved useful for examining subgeneric relationships and testing hypotheses on genus-wide divergence times, whereas the AFLP markers were suitable for studying relationships among closely related taxa and b…

Following a revision of Soldanella, we here synonymize 109 non-hybrid names of this genus. We also lectotypify or neotypify 17 names of Soldanella. These are S. alpina L., S. alpina F. W. Schmidt, S. alpina L. var. carestiae Cristofolini et Pignatti, S. alpina L. f. major Cristofolini et Pignatti, S. austriaca Vierh., S. carpatica Vierh., S. marmarossiensis Kldst., S. minima Hoppe, S. minima Hoppe subsp. samnitica Cristofolini et Pignatti, S. minima Hoppe f. latifolia Cristofolini et Pignatti, S. montana Mikan, S. montana Willd., S. montana Willd. subsp. faceta Kress, S. occidentalis Vierh., S. pusilla Baumg., S. pusilla Baumg. f. calcicola Vierh., and S. pusilla Baumg. var. chrysosplenifol…
The systematics of Soldanella (Primulaceae) based on morphological and molecular (ITS, AFLPs) evidence
2002
Based on the observation of more than 6300 herbarium specimens and molecular (ITS, AFLPs) evidence, Soldanella is divided into 16 species and four subspecies. Soldanella angusta, S. oreodoxa and S. rugosa are described as new, and the circumscriptions of S. marmarossiensis, S. major, S. pusilla ssp. pusilla and S. hungarica are emended. Nine hybrid names are lectotypified. All non-hybrid taxa are described in detail and distribution maps are provided. Interspecific relationships are discussed on the background of morphological and molecular variation.
Isozyme uniformity in a wild extinct insular plant,Lysimachia minoricensisJ.J. Rodr. (Primulaceae)
1999
Isozyme analyses were conducted to evaluate the genetic diversity of seed accessions of Lysimachia minoricensis (a Balearic endemic plant that became extinct in the wild) provided by 10 European botanical gardens. No isozyme variation was detected after examination of the electrophoretic patterns of 22 putative loci in more than 150 plants. The lack of genetic variation in L. minoricensis is probably due to the shortage of sample propagules originally recovered in the field before its extinction. Extant plants of L. minoricensis are believed to have originated from a single source, therefore limiting their use as seed stocks for restoration projects.
Evolution, ecology and systematics of Soldanella (Primulaceae) in the southern Apennines (Italy)
2015
Background The populations of Soldanella (Primulaceae) of the southern Apennines (Italy) are unique within the genus for their distribution and ecology. Their highly fragmented distribution range, with three main metapopulations on some of the highest mountains (Gelbison, Sila and Aspromonte massifs) of the area, poses intriguing questions about their evolutionary history and biogeography, and about the possibility of local endemisms. Aims and methods In order to clarify the phylogeny and biogeography of the three metapopulations of Soldanella in the southern Apennines, attributed to S. calabrella to date, and to identify possible local endemisms, a comparative approach based on the study o…
Past, present and future of mountain species of the French Massif Central - the case ofSoldanella alpinaL. subsp.alpina(Primulaceae) and a review of …
2012
Aim Our goals were: (1) to investigate patterns of genetic variation in the French Massif Central (MC) of Soldanella alpina (Primulaceae), an alpine plant species that has only one known population in the region; (2) to analyse these patterns in order to deduce the Quaternary history of the population and to predict how current climatic warming may affect it; and (3) to review molecular analyses from the MC to evaluate the importance of the region for the conservation of genetic diversity. Location Europe, with a special focus on the French Massif Central and adjacent regions. Methods Amplified fragment length polymorphisms (AFLPs) were analysed for 192 individuals (nine populations) of …

New Alkenylresorcinols with Cytotoxic and Antimicrobial Activities from the Leaves of Embelia schimperi.
2020
AbstractA phytochemical study of the methanol extract of the leaves of Embelia schimperi resulted in the isolation of three new alkenylresorcinols, 1 – 3, together with the known analogs 4 – 7. Their structures were established by a combination of spectroscopic techniques. Compounds 1 – 7 exhibited moderate cytotoxic activity against human cervical cancer cells HeLa-S3 and more pronounced antimicrobial properties towards bacteria and filamentous fungi. The present study falls into an ongoing research project on the characterization of bioactive phenolic lipids from plants of the family Primulaceae.
Parallel evolution of flower reduction in two alpineSoldanellaspecies (Primulaceae)
2014
The European endemic Soldanella has traditionally been divided into two morphologically well-defined sections. Section Tubiflores contains two species growing in high-elevation habitats, whereas most of the 14 species of section Soldanella inhabit montane forests. Section Tubiflores has a reduced floral morphology compared with section Soldanella. A previous phylogenetic study based on internal transcribed spacer (ITS) and AFLP data has revealed that, although the genus Soldanella itself is monophyletic, both sections are paraphyletic. Soldanella alpina (section Soldanella) forms a clade with S. minima and S. pusilla (section Tubiflores), and the grouping of S. alpina with S. pusilla has be…
