Hybridization And Introgression

Based upon a thin-layer chromatographic study of the phenolics of young leaves of the species of the genus Aegilops, in which affinities both within and among diploid and polyploid groups were compared, the following conclusions were drawn. No new compounds were found in the polyploid Aegilops species. A. ovata must have arisen from A. umbellulata and A. comosa. A. columnaris probably contains genetic material derived from members of the Sitopsis section. A. biuncialis contains parts of the genome of A. comosa and parts from some member of the Sitopsis section. A. variabilis contains an S or modified S genome. A. triuncialis contains the C and Cu genomes. A. cylindrica contains the genomes C and D. A. crassa(4x) has an S genome in its constitution. A. ventricosa seems to contain parts of the A. caudata genome. A. crassa (6x) contains one D genome, probably from A. squarrosa, one from A. bicornis, and the third genome appears to contain parts from the M and S genomes. A. juvenalis and A. triaristata (6x) contain a modified S genome.The present study supports the hypothesis that extensive natural hybridization and introgression has taken place during the evolution of the polyploid species.

Hybridization And Introgression

AbstractIn order to elucidate the extent of natural hybridization and gene introgression between two Japanese pond frog species, Rana nigromaculata and Rana porosa porosa, 16 pond frogs from the Sengokuhara population in the Hakone district in central Japan were analyzed for morphological characters, allozymes, mtDNA and reproductive capacity. The results revealed that they consisted of pure Rana nigromaculata, F1 hybrids and a backcross hybrid.

AbstractNatural hybridization and introgression is recorded between the newt species Triturus vulgaris and T. montandoni in Slovakia. To confirm a hybrid status of two putative hybrids, morphological and Randomly Amplified Polymorphic DNA (RAPD) markers specific for T. vulgaris and T. montandoni were used. The individuals found in Zbojská (Veporské vrchy Mts, Slovakia; analyzed morphologically and genetically) and Zubrohlava (Oravská kotlina basin, Slovakia; analyzed only morphologically) possessed markers of both species. Segregation of RAPD markers together with a model-based Bayesian analysis revealed that the specimen from Zbojská belonged to later generation hybrids.
