Abstract
In this study, the banded karyotypes (C- and Ag-nucleolus organizer regions (NORs)) of Myotis emarginatus in Turkey were determined for the first time. The karyotype contained 44 chromosomes, the number of chromosomal arms (NF) was 54, and the number of autosomal arms (NFa) was 50. Slight C-heterochromatic blocks were observed in the centromeric regions of some autosome pairs, whereas the sex chromosomes were euchromatic. The Ag-NORs were detected in the short arms of a large and a medium-sized acrocentric autosome. The distribution of C-heterochromatin regions in Turkish populations of M. emarginatus is similar to those reported in some other Myotis species.
Highlights
In this study, the banded karyotypes (C- and Ag-nucleolus organizer regions (NORs)) of Myotis emarginatus in Turkey were determined for the first time
There are 11 species of vespertilionid bats belonging to the genus Myotis in Turkey (Benda and Horacek, 1998; Benda and Karataş, 2005)
The aim of this paper was to perform a chromosomal banding analysis with C-band and Ag-NOR staining for the karyotype of this species from several sites in Turkey
Summary
The banded karyotypes (C- and Ag-nucleolus organizer regions (NORs)) of Myotis emarginatus in Turkey were determined for the first time. There are 11 species of vespertilionid bats belonging to the genus Myotis in Turkey (Benda and Horacek, 1998; Benda and Karataş, 2005). The vespertilionid bats were examined cytogenetically in different regions of the world (Zima and Horacek, 1985) and they show very low karyological diversity at the population, species, and genus levels (Reina et al, 1994).
