- 論文の詳細を見る
To obtain a detailed karyotype of Rhodeus ocellatus (2n=48), we employed bromodeoxyuridine (BrdU) replication banding method. All chromosome pairs were identified by R-banding patterns. Fluorescence in situ hybridization (FISH) using a ribosomal DNA probe exhibited that 5S rDNA was located at a centromeric region of one pair of acrocentric chromosomes. However, the silverstained nucleolar organizer regions (Ag-NORs) located at a different acrocentric pair of the smallest one, demonstrating that the Ag-NOR loci did not show the 5S rDNA loci in this species. These results indicate a new karyotypic characteristics in this species. Moreover, the karyotypical difference between the present species and the related species of Acheilognathus tabira (2n=44) was briefly discussed.
