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

The south American rodent Graomys griseoflavus exhibits a remarkable chromosome polymorphism as a consequence of four Robertsonian fusions. Focusing on the genetic analysis of the taxon, genome organization of all karyomorphs was studied at chromosome and molecular organization level. Cytogenetic (G...

description The south American rodent Graomys griseoflavus exhibits a remarkable chromosome polymorphism as a consequence of four Robertsonian fusions. Focusing on the genetic analysis of the taxon, genome organization of all karyomorphs was studied at chromosome and molecular organization level. Cytogenetic (G, NOR and Re banding) and molecular (satellite and mitochondrial DNAs) events accompanying chromosome divergence allowed tracing a phylogenetic relationship among all karyomorphs. Available data led to propose that chromosome evolution of G. griseqflavus occurred in a non-random sequence of centric fusions, supporting the hypothesis of single origin for Robertsonian karyomorphs.
