Аннотация: Sokolov’s dwarf hamster ( Cricetulus sokolovi ) is the leaststudied representative of the striped hamsters ( Cricetulusbarabensis species group), the taxonomy of which remainscontroversial. The species was described based on chromosomemorphology, but neither the details of the karyotypenor the phylogenetic relationships with other Cricetulus areknown. In the present study, the karyotype of C. sokolovi wasexamined using cross-species chromosome painting. Molecularand cytogenetic data were employed to determine thephylogenetic position of Sokolov’s hamster and to analyzethe potential pathways of chromosome evolution in Cricetulus.Both the chromosome and molecular data support thespecies status of Sokolov’s hamster. Phylogenetic analysis ofthe CYTB data placed C. sokolovi as sister to all other stripedhamsters (sequence divergence of 8.1%). FISH data revealedthat the karyotype of C. sokolovi is highly rearranged, withthe most parsimonious scenario of its origin implying at least4 robertsonian events and a centromere shift. Comparativecytogenetic data on Cricetinae suggest that their evolutionaryhistory includes both periods of chromosomal conservatismand episodes of rapid chromosomal change.
