Genetická štruktúra a diverzita predpokladaných hybridných rojov borovice lesnej (Pinus sylvestris L.) a borovice horskej – kosodreviny (P. mugo Turra) na severnom Slovensku
Genetic structure and diversity of putative hybrid swarms of Scots pine and mountain dwarf pine in northern Slovakia

Annotation: The aim of the present study is to analyze genetic structure and diversity of putative hybrid swarms of Scots pine (Pinus sylvestris L.) and mountain dwarf pine (P. mugo Turra) in northern Slovakia. The localities of their occurence include peat-bogs in Horná Orava region, namely Medzi Bormi near Zuberec, Tisovnica near Oravská Polhora, and Rudné near Suchá Hora. Hybrid status is also suggested for several individuals on the rocky locality Obšívanka – Sokolie near Terchová (Malá Fatra). To study these populations, the nuclear simple sequence repeats (SSR) will be used. Within-population genetic variation will be evaluated by the concept of genetic structure and diversity, and results will then be used to determine among-population variation (genetic differentiation). Ultimately, this should contribute to specifying the phylogenetic relationships of the respective hybrid swarms with their putative parent taxa.

Genetická štruktúra hybridných rojov borovice lesnej a borovice horskej na Slovensku
Genetic structure of hybrid swarms of Scots pine and dwarf mountain pine in Slovakia
Program: VEGA
Zodpovedný riešiteľ: RNDr. Kormuťák Andrej DrSc.
Annotation: The project aims in description of genetic status of the putative hybrid swarms of Scots pine (Pinus sylvestris L.) and dwarf mountain pine (Pinus mugo Turra) in northern Slovakia. The attention will be paid to comparison of genetic structure of the putative hybrid swarms Medzi Bormi in Zuberec-Habovka, Tisovnica in Oravska Polhora, Sucha Hora and Obšívanka-Sokolie near Terchova with the structure of selected reference populations of pure species P. mugo and P. sylvestris. As genetic markers, the microsatellites of the nuclear genes and tandem repeated retrotranspozons of nuclear DNA (iPBS) will be used. Obtained experimental data will serve in calculation the basic characteristics of genetic structure in individual populations and subsequent drawing the conclusions about genetic distance between them as the main indication of their resemblance or differentiation.
