| description: | The project envisages to continue and extend the studies of evolution and systematics in the grass genus Bromus and the legume genus Vicia supported by our ending Estonian Science Foundation Grant No.4082 for 2000-2003. The project combines traditional morphology-based botanical systematics, biochemical isozyme analyses, genetics, and chromosome cytology for solving problems of phylogenetic systematics, phylogeography and evolution in botany. The main objectives of the project are: 1. To determine genetic divergence and relationships within and among species Bromus hordeaceus, B. secalinus, B. racemosus and B. commutatus of type section of genus Bromus by cladistic and phenetic analysis of isozymes with checking the correspondence of the results with the traditional morphological species delimitation. 2. A study of genetic divergence and phylogenetic relationships among species, sections and subgenera of genus Vicia by cladistic and phenetic analysis of isozymes and morphology with analysing the correspondence of results with traditional taxonomic treatments. 3. Evaluation of genetic diversity and breeding system in a presumable progenitor-derivative species complex Bromus arvensis - B. intermedius in relation to their evolution. 4. To assess intraspecific variation of isozymes, chromosome numbers and morphology in some taxonomically problematic species complexes, e. g . the Bromus diandrus sensu lato, Vicia sativa sensu lato and the V. cracca-tenuifolia complex. 5. To compare genetic diversity in some wideaspread annual weedy bromes in their native Near East and colonized European regions in order to study their migration history and to locate areas of high diversity and unique variation, e. g. in Bromus sterilis and B. hordeaceus. |
