| Abstract |
The karyotypes and other chromosomal characteristics of the Orange-lined triggerfsh (Balistapus undulatus) from the Gulf
of Thailand (Pacifc Ocean) were studied, using conventional cytogenetic analyses and fuorescence in situ hybridization
using 18 S, 5 S rDNA, together with (CA)15, (GA)15, and (CAA)10 microsatellites as probes. The results showed 2n=42
(42t; NF=42) in both male and female fsh, and that the sex chromosomes could not be distinguished from one another.
The centromeric regions in all the chromosomes showed distinct patterns in the distribution of C-positive heterochromatin.
The NORs were localized as single pairs, which coincide with the 18 S rDNA probe’s location. At the sub-centromeric
region of the telocentric chromosome, the 5 S rDNA probe’s bright signal was discovered. The (CA)15, (GA)15, and (CAA)10
microsatellites are sparsely distributed along all the chromosomes. Of these, the (GA)15 sequence, exhibits preferential
accumulation at the telomere of chromosome pair 18. The study also suggests that species B. undulatus and Odonus niger
are karyotypically similar, necessitating the need for detailed analyses of chromosomal rearrangements with sophisticated
cytogenetic techniques to elucidate their further diferentiation. |
