Cryptic Speciation and Chromosomal Repatterning in the South African Climbing Mice Dendromus (Rodentia, Nesomyidae)
We evaluate the intra- and interspecific diversity in the four South African rodent species of the genus Dendromus. The molecular phylogenetic analysis on twenty-three individuals have been conducted on a combined dataset of nuclear and mitochondrial markers. Moreover, the extent and processes underlying chromosomal variation, have been investigated on three species by mean of G-, C-bands, NORs...
متن کاملExtensive chromosomal repatterning and the evolution of sterility barriers in hybrid sunflower species.
New species may arise via hybridization and without a change in ploidy. This process, termed homoploid hybrid speciation, is theoretically difficult because it requires the development of reproductive barriers in sympatry or parapatry. Theory suggests that isolation may arise through rapid karyotypic evolution and/or ecological divergence of hybrid neospecies. Here, we investigate the role of k...
متن کاملNew Insights into Phasmatodea Chromosomes
Currently, approximately 3000 species of stick insects are known; however, chromosome numbers, which range between 21 and 88, are known for only a few of these insects. Also, centromere banding staining (C-banding) patterns were described for fewer than 10 species, and fluorescence in situ hybridization (FISH) was applied exclusively in two Leptynia species. Interestingly, 10-25% of stick insec...
متن کاملAgNOR STAINING IN MALIGNANT AND BENIGN EFFUSIONS
Objective: To evaluate the correlation of argyrophilic nucleolar regions(AgNORs) and malignancy in benign and malignant effusions. Design: The study group consisted of pleural and peritoneal effusion samples obtained from patients suffering from various benign or malignant diseases. The cytological smears were studied by conventional haematoxylin & eosin(H&E) and silver staining for AgNORs. Set...
متن کاملDNA methylation specifies chromosomal localization of MeCP2.
MeCP2 is a chromosomal protein that is concentrated in the centromeric heterochromatin of mouse cells. In vitro, the protein binds preferentially to DNA containing a single symmetrically methylated CpG. To find out whether the heterochromatic localization of MeCP2 depended on DNA methylation, we transiently expressed MeCP2-LacZ fusion proteins in cultured cells. Intact protein was targeted to h...
