The South American rodent Graomys griseoflavus is a species with a Robertsonian (Rb) autosomal polymorphism. A marked genetic differentiation between 2n=42-41 and 2n=38- 34 karyomorphic groups was evidenced by cytogenetic and molecular analysis. The mitochon- drial control region was sequenced in all Graomys karyomorphs for its characterization and used to trace more accurate phylogenetic relationships. The molecular organization showed to be coincident with the consensus molecular structure…

Chromosomal variability and morphological notes in Graomys griseoflavus (Rodentia, Cricetidae, Sigmodontinae), from Catamarca and Mendoza provinces, Argentina

The presence of more than one heterozygous fusion in several localities refute the hypothesis proposed for this species that for a new fusion to be generated the others must occur in homozygosis, contrasting previous hypothesis about its karyo- typic evolution.

Complete mitochondrial genome of the Eurasian flying squirrel Pteromys volans (Sciuromorpha, Sciuridae) and revision of rodent phylogeny

In this study, the complete mitochondrial genome of the Eurasian flying squirrel Pteromys volans was sequenced and characterized in detail, and phylogenetic relationships among the five rodent suborders were suggested and discussed in detail.

Patterns of speciation in two sibling species of Graomys (Rodentia, Cricetidae) based on mtDNA sequences

The mismatch distribution analyses suggest that the geographical and demographic expansion undergone by the species is related to the climatic events that occurred in the region during the Quaternary, which is consistent with a process of recent speciation.


The authors' results suggest that Chumbicha's specimens are conspecific with G. centralis, and other data of the genus suggest that the name G. chacoensis should be applied to specimens with 2n = 42.



Phylogenetic relationships among Robertsonian karyomorphs of Graomys griseoflavus (Rodentia, Muridae) by mitochondrial cytochrome b DNA sequencing.

Three trees were produced showing the 2n = 38-34 karyomorphs grouped in a single clade while the 2 n = 42-41 animals formed a different one, in agreement with a hypothesis of a single origin for 2n-34 Robertsonian karyomorphic animals from the ancestral 1n = 42.

Patterns of evolution in Graomys griseoflavus (Rodentia, Muridae). IV. A case of rapid speciation

Values of interspecific genetic identity were similar to those obtained for conspecific populations, suggesting that fixation of Robertsonian fusions would have occurred without significant bottlenecks, and lack of correlation between gene flow levels and geographical distance between population pairs would indicate a recent and fast colonization of its distribution areas by the derived species.

Molecular analysis of chromosomal polymorphism in the South American cricetid,Graomys griseoflavus

It is suggested that heterochromatic EG250 DNA provides a favourable molecular environment for Robertsonian fusion occurrence, while lack of banding would be due to decondensed EG250 subfamilies becoming an easier target for chromosomal restriction.

Loss of nucleolar organizer regions during chromosomal evolution in the South American cricetid Graomys griseoflavus

Analysis of nucleolar organizer region (NOR) locations both by silver staining and in situ hybridization revealed that 2n=42 individuals exhibit highly variable Ag-NOR patterns, while specimens of the 2n−34 karyomorphic group showed a single Ag- NOR pattern.

Autosomal rearrangements in Graomys griseoflavus (Rodentia): a model of non-random Robertsonian divergence.

Cytogenetic and molecular events accompanying chromosome divergence allowed tracing a phylogenetic relationship among all karyomorphs and led to propose that chromosome evolution of G. griseoflavus occurred in a non-random sequence of centric fusions, supporting the hypothesis of single origin for Robertsonian kARYomorphs.

Lack of mitochondrial DNA divergence between chromosome races of the common shrew, Sorex araneus, in Sweden. Implications for interpreting chromosomal evolution and colonization history

The common shrew, Sorex araneus, has one of the most variable karyotypes among mammals, displaying numerous chromosome races throughout its distribution. The six chromosome races present in Sweden

Patterns of Evolution in Graomys griseoflavus (Rodentia: Muridae): II. Reproductive Isolation between Cytotypes

Interpopulation crosses showed that 2n = 36–38 animals were interfertile, indicating that these cytotypes belong to a single species complex, and results indicate that the 2 n = 42 cytotype is a separate sibling species from those of the 2n–38 complex.

DNA sequence variation in the mitochondrial control region of red-backed voles (Clethrionomys).

The complete mitochondrial DNA (mtDNA) control region was sequenced for 71 individuals from five species of the rodent genus Clethrionomys both to understand patterns of variation and to explore the

The evolutionary history of the two karyotypic groups of the common shrew, Sorex araneus, in Poland

The data on the cytochrome b gene variability support the hypothesis assuming the Robertsonian fusions having spread into an ancestral acrocentric distribution, and give no evidence for a recent bottleneck after the process of post-Pleistocene recolonization of Poland by the shrews.

Mitochondrial DNA variation and the evolution of Robertsonian chromosomal races of house mice, Mus domesticus.

The amount of mtDNA variation was as great among different R b races as among different populations of standard karyotype mice, suggesting that different Rb races do not derive from a single recent maternal lineage.
