Comparative study of four species (Bagridae, Siluriformes) from Thailand: insights into their karyotypic diversity.

Karyotypes of four catfishes of the genus Scopoli, 1777 (family Bagridae), Fowler, 1937, Roberts, 1992, (Bleeker, 1846) and (Bleeker, 1851), were analysed by conventional and Ag-NOR banding as well as fluorescence in situ hybridization (FISH) techniques. Microsatellite d(GC), d(CAA), d(CAT) and d(GAA) repeat probes were applied in FISH. The obtained data revealed that the four studied species have different chromosome complements.

Comparative karyotype study of three Cyprinids (Cyprinidae, Cyprininae) in Thailand by classical cytogenetic and FISH techniques.

Three species of ornamental fishes in the subfamily Cyprininae (family Cyprinidae) namely, (Fowler, 1934), (Fowler, 1934), Boonyaratpalin et Srirungroj, 1971 were studied by classical cytogenetic and fluorescent in situ hybridization (FISH) techniques. Chromosomes were directly prepared from kidney tissues and stained by using conventional and Ag-NOR banding techniques. Microsatellite d(CA) and d(CGG) probes were hybridized to the chromosomes of three cyprinids.
