- Аннотация: The present study attempts to derive phylogenetic relationships in shrews from the genera Sorex, Crocidura, Neomys and Suncus on the basis of modified RFLP analysis of genome DNA (taxonprint) and inter-SINE-PCR method (IS-PCR). Phylogenetic NJ and MP analyses of taxonprint both place Sorex and Neomys genera as a sister group to the Crocidura/ Suncus clade. These data also confirm the monophyletic origin of “S. araneus group.” In addition to this lineage the results of IS-PCR support another lineage within the Palearctic genus Sorex, which includes 42-chromosomal species of “S. caecutiens group” together with caryotypicaly related species of “S. minutus group,” S. minutissimus and S. raddei. Besides, the findings of the IS-PCR study are the close relations of N. fodiens and N. anomalus comparatively N. Schelkovnicovi and the distinct position of the specimens of C. gueldenstaedtii from the C. suaveolens as well as C. sibirica specimens. Our results demonstrate the availability of IS-PCR data for resolving difficult phylogenetic questions arising from discordant morphological, karyological biochemical and mtDNA data.
