Trachelyopterus coriaceus View in CoL :

Araguaia River basin. Diploid number was 58 chromosomes and karyotype was composed of 20 metacentric, 18 submetacentric, 12 subtelocentric, and 8 acrocentric ( Fig. 1C View FIGURE 1 ). AgNO 3 staining revealed simple NORs allocated in terminal region on the short arm of the submetacentric chromosome pair 23 ( Fig. 1C View FIGURE 1 , in box). C-banding evidenced pale heterochromatin in terminal regions on almost all karyotype pairs ( Fig. 1F View FIGURE 1 ). 18S rDNA-FISH also revealed only the pair 23 with these sites, corresponding to what was evidenced by the AgNO 3. 5S rDNA-FISH probe detected these sites on the short arm of the metacentric pair 3 and on the long arm of the submetacentric pair 16 ( Fig. 1I View FIGURE 1 ).
