Opis:
Background: Simple sequence repeats (SSRs) are widespread molecular markers commonly used in population genetic studies. Nowadays, next-generation sequencing (NGS) methods allow identifying thousands of SSRs in one sequencing run, which greatly facilitates isolation and development of new SSRs. However, their usefulness as molecular markers still must be tested empirically on a number of populations to select SSRs with best parameters for future population genetic research. An alternative approach, cheaper and faster than isolation and characterization of new SSRs, involves cross-amplification of SSRs in closely related species. Aims: Our goal was to develop multiplex PCR protocols that will be useful in population genetic studies of Scots pine (Pinus sylvestris L.) and dwarf mountain pine (P. mugo Turra), and possibly other pine species. Methods: We tested 14 chloroplast (cpSSRs) and 22 nuclear (nSSRs) microsatellite markers originally designed for Japanese black pine (P. thunbergii Parl.), P. sylvestris and loblolly pine (P. taeda L.) in four populations of P. sylvestris and P. mugo across different locations in Europe. We designed six multiplex PCRs, which were subsequently screened for their ability to provide repeatable and high quality amplification products using capillary electrophoresis. Results: The transfer rate in our study was similar in both pine species, and it was very high for cpSSRs (93% and 86% for P. sylvestris and P. mugo, respectively) and moderate for nSSRs (59% for both species). We managed to design five well-performing multiplex reactions out of six initially tested. Most of the tested loci were polymorphic. Moreover, the allelic patterns detected at some cpSSRs were species-specific. Conclusions: We provide a set of five multiplexes which can be used in genetic studies of both P. sylvestris and P. mugo. Chloroplast marker PCP30277 is a good candidate for a cheap species diagnostic marker suitable for tracking interspecific gene flow between hybridizing species of P. sylvestris and P. mugo.

Opis:
A syntaxonomical revision of plant communities with dominant Pinus mugo in the Western Carpathians is presented. The data set of 341 relevés was examined and analysed using the detrended correspondence analysis and the cluster analysis. Major gradients and clusters were interpreted using Ellenberg’s indicator values. The major gradient in species composition was associated with available nutrients and moisture. The authors suggest distinguishing the dwarf pine stands of the supramontanous and subalpine belts of the Western Carpathians referred to the alliance Pinion mugo Pawłowski in Pawłowski et al. 1928 of the order Junipero-Pinetalia mugo Boşcaiu 1971 and the class Roso pendulinae-Pinetea mugo Theurillat in Theurillat et al. 1995, into three separate associations: the Cetrario-Pinetum mugo Hadač 1956, the Homogyno alpinae-Pinetum mugo (Sillinger 1933) nom. nov., and the Adenostylo alliariae-Pinetum mugo (Sillinger 1933) Šoltésová 1974. The authors also elucidated the unauthorized name of the association Vaccinio myrtilli-Pinetum mugo Hadač 1956, which is a younger homonym of the valid name of the association Vaccinio myrtilli-Pinetum montanae Morton 1927 that characterises the acidophilous dwarf pine stands on calcareous bedrocks in the Alps.

Opis:
Pinus uliginosa is an interesting taxon from the Pinus mugo complex with controversial systematic position andspecific characteristics, intermediate among P. mugo, P. uncinata and P. sylvestris. The peat-bog pine is rare andprotectedin Poland. All its’ known populations have a relict character andare slightly different from each other. The aim of the present study was comparison of the individuals from the Czarne Bagno of the “Torfowisko pod Zieleńcem” Nature Reserve (Sudetes), determined in the field on the basis of morphological characteristics as Pinus uliginosa, with four samples of this taxon from the northern limits of its range in PolandandGer - many andwith Pinus sylvestris, P. mugo and P. uncinata, to verify morphological andtaxonomic relations between them. The material collected from 30 individuals determined as P. uliginosa, was closest to populations of P. uliginosa from the Bory Dolnośląskie, andto P. mugo from the Tatra Mts., concerning the needle characters. The cone characteristics of P. uliginosa individuals from the Czarne Bagno appeared similar to all other of that taxon. In spite of that, the cone characters first of all differentiate P. uliginosa from P. sylvestris, P. mugo and P. uncinata. The combination of needle and cone morphological characters are a good tool to distinguish P. sylvestris, P. uncinata, P. mugo and P. uliginosa with a very high probability.

Opis:
The needles of 17 samples representing 15 populations of Pinus mugo Turra from the Alps, Apennines, Sudethians, Carpathians and Rhodopes were analysed in respect to 15 morphological and anatomical characters. The results of measurements were analysed statistically. The variation of the samples was generally not to large. Populations from the East Carpathians appeared different from all other examined. Two formed groups of analysed populations are separated mainly by thickness of epidermal cells, width/thickness of epidermal cell ratio, needle width and needle thickness. The differences between two groups of populations suggest their longer separation during Pleistocene.

Opis:
The genetic diversity within and among twelve populations (379 individuals) of Pinus mugo from the Giant Mts., Carpathians and Alps was analyzed using ten chloroplast microsatellite markers. A stepwise mutation model (SMM) for microsatellite loci was used in order to estimate divergence between populations and provenances from three mountain ranges. High levels of genetic diversity and significant differentiation were found among the three population groups. The populations from Giant Mts., Carpathians and Alps were strongly differentiated between each other, while differences among populations within these massifs were much lower. The pattern of genetic structure observedin dwarf mountain pine can be characteristic in conifers with a disjunctive geographic distribution. The significant genetic structuring among isolated parts of the geographic range of the species may be a result of an ancient fragmentation andlong lasting geographic isolation between the Giant Mts., Alpine and Tatra populations of P. mugo.

Opis:
The main aim of this study was to describe the variation between the populations of the dwarf mountain pine Pinus mugo Turra based on the morphological and anatomical traits of their needles, and to investigate the relationship between the observed variation and environmental conditions (altitude and substrate).Two-year-old needles were collected from 180 individuals of six populations of P. mugo growing in the Tatra Mts. Two populations were classified as dense, located at 1360–1450 m altitude, and the remaining four formed loose clusters and were situated at 1500–1650 m altitude. Four of the populations are growing on granite and two on a limestone substrate. The natural variation of 10 morpho-anatomical and 3 synthetic needle traits was measured. In addition to descriptive statistics, the analyses of variance (ANOVA) with a Tukey test and principal component analysis were computed. We also estimated Pearson correlation coefficients for the examined needle traits and altitude as well as substrate. Our results indicate that the P. mugo populations differ significantly with regard to the investigated traits for which the Trzydniowiański Wierch population was the most distinct. The observed pattern of variability is largely caused by differences in stomatal traits and these features are positive correlated with altitude. Additionally, populations growing on granite have larger values for most of the examined traits compared to populations growing on limestone.

Opis:
Study characterizes fractional composition of humic substances in the forest soils under mountain dwarf pine in subalpine region of the East Sudety Mountains (SW Poland). Organic matter in acidic mountain conditions is characterized by low humification ratio and high content of fractional groups. Negative processes leading to decay of mountain dwarf pine affect decreasing carbon stocks and changes in morphology of organic horizon.
