General Data about the project
PROJECT TITLE: Construction synthetic geographic maps of present genetic diversity and postglacial history for white oaks and hornbeam species from Romania and Bulgaria
Objectives of the Project:
The aim of this project is to provide geneticists and foresters from Romania and Bulgaria with an integrated description of 10 temperate forest tree species in the form of synthetic geographic maps based on cpDNA (chloroplast DNA) polymorphism variation.
The specific objectives are:
a) Evaluation cpDNA polymorphism for eight sympatric oak species belonging to the subgenus Lepidobalanus: Q. pedunculiflora, Q. frainetto, Q. pubescens, Q.virgiliana, Q. petraea, Q. robur, Q. hartwissiana, and Q. protoroburoides
b) Evaluation cpDNA polymorphism for hornbeam species: Carpinus betulus and Carpinus orientalis.
c)Mapping the geographic distribution of the cpDNA polymorphism and delineation post glacial recolonisation routes for studied 10 temperate forest tree species.
d) Dissemination project results by joint scientific articles and participation at national and international conferences.
The conservation of forest genetic resources in the Balkans is one of the ecological greatest challenges being on of the greatest European biodiversity hot spot that is poorly understood.
Both in Romania and Bulgaria there is a big interest and willingness to realize common projects to analyze and to evaluate genetic diversity of forest tree species with widely distribution in the Balkans.
The aim of present project is to contribute with new knowledge regarding present genetic diversity and spatio-temporal evolution of 10 temperate forest tree species from Romania and Bulgaria.
In the framework of present project would be applied modern research methods to assess genetic diversity with DNA chloroplast markers. The advantage of cpDNA markers represents the possibility to evaluate and to establish the autochthony of studied forest genetic resources.
Compiled synthetic geographic maps based on cpDNA polymorphism would be used as a reference maps at national, regional and European level to check geographic origin of seed lots.
The synthetic geographic maps of cpDNA polymorphism will allow to trace retrospectively the post glacial recolonisation routes of temperate forest trees from the Balkans refugial areas.
The present project envisages to construct synthetic maps of present genetic diversity and postglacial history by sampling sympatric oak species and hornbeam species from Romania and Bulgaria.
For this purpose cpDNA polymorphism for eight sympatric oak species belonging to the subgenus Lepidobalanus; would be studied: Q. pedunculiflora, Q. frainetto, Q. pubescens, Q.virgiliana, Q. petraea, Q. robur, Q. hartwissiana, and Quercus protoroburoides.
Also cpDNA polymorphism for hornbeam species: Carpinus betulus and Carpinus orientalis would be investigated. Investigation of hornbeam species is very important for this project because palaeogeographical researches illustrated a unique episode in the forest history in Europe, which was defined by a hornbeam layer between oak and spruce forest, specific for Carpathian and Balkan Mountains. These make one of the regional differences between the postglacial vegetation history of Balkans and Western Europe.
The achieved new knowledge would contribute to dynamic conservation of oaks and hornbeam forest genetic resources at national level based on scientific genetic concepts.
Synthetic geographic maps will be produced at the end of the project that will summarize the geographic distribution of cpDNA polymorphism of studied species
The achieved project results would promote participation of Bulgaria and Romania research institutions to European projects.
