... = 21, all acrocentric), are described and compared on the basis of conventional (C-banding, DAPI/CMA 3 -staining, Ag-NOR) and molecular (FISH with 18S rDNA and telomeric probes) cytogenetic staining methods. This is the first study to report karyotypes of A. beybienkoi and P. caelestis . Differential...

... evolutionary history. Thus, we also used 18S rDNA FISH (18S-NOR) as previously applied to a few turtle taxa [Kawai et al., 2007; Cleiton and Giuliano-Caetano, 2008; Badenhorst et al., 2013, 2015; Kawagoshi et al., 2014] to detect potentially inactive NOR copies that may have passed undetected in some...

...), Paramiopsalis aff. ramulosus Juberthie, 1962 (2n = 28; Sironidae), Cyphophthalmus duricorius Joseph, 1868 (2n = 24; Sironidae), and Siro carpaticus Rafalski, 1956 (2n = 52; Sironidae) was performed. Fluorescence in situ hybridization with 18S rDNA probe was used to analyze the distribution of major ribosomal...

..., nucleolus organising regions (NORs) and sex chromosome behaviour during meiosis of the entelegyne Wadicosa fidelis (Lycosidae). Preparations stained by Giemsa were used to study karyotype and meiosis. NORs were visualised by silver staining and fluorescence in situ hybridisation with 18S rDNA probe...

... pericentromeric C-band was detected in a single pair, equivalent to the X 1 chromosome. No markers on X 2 chromosomes were detected, but they could be identified by their size. The females displayed the same distribution of C and chromomycin A 3 bands and 18S rDNA sites among the populations. However, the males...

... banding) as well as fluorescent in situ hybridization (FISH) to detect 18S rDNA, 5S rDNA, and 5S Hin dIII satellite DNA sites. The isolation, cloning and characterization of an 18S rDNA probe from H. malabaricus genome were also performed for the first time in order to develop a more specific probe. The 3...
