RAPDs in representatives of the genus Sorex, including chromosome races of Sorex araneus // Russian J. Theriol. Vol.6. No.1: 2733 [in English].

ABSTRACT. We analysed genetic divergence between species of the genus Sorex (S. araneus, S. caecutiens, S. minutus and S. minutissimus) using the RAPD (random amplified polymorphic DNA) method. We also examined RAPDs in 26 individuals of six chromosome races of the common shrew (Moscow, Ilomantsi, St. Petersburg, Neroosa, Penza, and Sok) from the European part of Russia. Nine primers were used for the detection of 24 to 79 fragments. The number of clearly identified DNA fragments by all primers was 539. Loci specific for different chromosome races of S. araneus were revealed. On the basis of summary matrices of the RAPD spectrum for nine primers, trees showing the genetic divergence were constructed. This study demonstrated the value of RAPDs for the analysis of relationship between species and chromosome races in Sorex. KEY WORDS: common shrew, Sorex araneus, chromosome races, RAPDs, RAPD-PCR.
