The Ranunculus auricomus complex is an interesting model system for studying the evolution and diversity of apomictic polyploid complexes. It comprises hundreds agamospecies, usually referred to two distinct morphotypes (traditionally named "R. auricomus" cassubicus") which are connected by several intermediate forms. Here we try elucidate "cassubicus" test criteria different classification concepts combining information molecular phylogenetic, morphological, karyological population genetic...
Three alien Solidago species of North American origin have become naturalized in Europe. While S. canadensis and gigantea are considered among the most aggressive plant invaders, altissima is rarely found. Here, detailed karyological variation cytogeography central Europe genetic relationships cytotypes elucidated their native other invaded areas. Almost 4,800 plants from 800 sites across were studied using flow cytometry complementary chromosome counting. A representative subset was...
Abstract Members of the Pilosella alpicola species group (Asteraceae) are distributed throughout alpine region European mountains (Alps, Carpathians, Balkan mountains). Like other groups ( Hieracium subg. ), taxonomy and species' relationships poorly understood mostly due to widespread facultative apomixis, frequent hybridization polyploidization—the most important phenomena substantially involved in evolutionary history genus. We assessed morphology, ploidy level, variation breeding system...
Abstract The Balkan Peninsula, with many endemic species, is known as one of the most important speciation and diversification centres in Europe. Here, we present a study western populations polymorphic European V. suavis s.l., which have been reported under name adriatica, but their taxonomic status position within genus remained uncertain. Viola s.l. nine close relatives sampled across Europe were subjected to molecular (sequencing nuclear ribosomal internal transcribed spacers amplified...
Four different cytotypes have been reported for Senecio jacobaea L. ssp. throughout Europe, with the most common occurrence of tetraploids (2n = 40). Here we present a survey previously published chromosome number data on this subspecies and its geographical distribution, focus populations from Pannonia Carpathians. Two ploidy levels determined in study area, using counting flow cytometry: tetraploid 40) octoploid 80). Fifty-one originating Slovakia, Austria, Czech Republic, Hungary, Ukraine...
Background and Aims Violaspecies are commonly grown for their ornamental flowers, but evolutionary history taxonomy often complicated have been poorly explored so far. This is a study of the polymorphic, typically blue-flowered species Viola suavis, concentrating on white-flowered populations uncertain taxonomic assignment that occur in Spain central south-eastern Europe. The aim was to resolve origin status intraspecific structure (post)glacial this species.
Violasuavisvar.pannonica (Violaceae) from central Europe is described here as a new variety to science. It most similar the blue-flowered V.suavisvar.suavis and white-flowered V.suavisvar.catalonica V.suavissubsp.naqshii, but exhibits differences in several characters, such petal colour, spur shape, fimbriae length on stipules, bracteoles position peduncle lamina sinus shape. Although taxon often considered colour mutation of V.suavisvar.suavis, previous genetic analyses revealed that these...
Fallopia sect. Reynoutria members (knotweeds) represent one of the most invasive alien plants in Europe. However, several aspects their biology, including cytological variation are poorly understood. Specifically, some taxa have multiple ploidy levels and frequency cytotypes seeds seedlings does not correspond to that recorded adult plants. In this study, flow cytometry was used determine relative genome size 1,106 established knotweeds (960 populations) collected Western Carpathians...
Detailed knowledge about the karyological diversity of organisms undoubtedly represents one crucial steps toward a better understanding their evolutionary trends and history. We investigated cytotype absolute genome size (AGS) patterns in European mountain-dwelling genus Soldanella (Primulaceae) light its geographic distribution ecological diversification.Our chromosome number survey was based on 34 newly determined 125 previously published counts. AGS estimated basis propidium iodide (PI)...
To reveal the general cytogeographical pattern of Cyanus section Protocyanus in Europe, DNA ploidy and/or chromosome numbers were newly examined for 160 populations by flow cytometry (450 plants) counting (30 plants). Furthermore, previously published karyological data revised (236 records). Our analyses confirmed counts 2n = 22 all investigated samples C. triumfetti group (the records semidecurrens and ternopoliensis are new), diospolitanus achtarovii; 44 montanus mollis; 20 lingulatus,...
The pronounced morphological variation of the Cyanus triumfettii group (syn. Centaurea s. latissimo) in western Carpathians and Pannonia has resulted confusing contradictory taxonomic treatments. We focus on identity populations which have been treated as C. subsp. this area. Karyological data were used to compare 47 (746 plants) from Carpatho–Pannonian area with 8 (105 type locality its vicinity southern part Alps. Chromosome counting flow cytometry confirmed diploid level for all analysed...
Morphometric comparison of three taxa the Senecio nemorensis group, namely S. germanicus Wallr., L. and a new species dacicus Hodálová & Marhold is presented. dacicus, representing plants with eight ligules from Romanian Carpathians, previously identified as L., shown to be clearly distinct Siberian nemorensis, which include lectotype this Linnaean name. Detailed data on distribution are Numerical methods used principal components analysis, cluster canonical non-parametric classificatory...
