“…In a comparative study with slow loris and monkeys in Thailand, we found that slow loris, Assam macaque, M. assamensis (2n=42); long-tailed macaque, M. fascicularis (2n=42); rhesus monkey, M. mulatta (2n=42) and pig-tailed macaque, M. nemestrina (2n=42) had NORs on short arms near the centromere of autosomes pair 13 as type of metacentric chromosomes (Tanomtong et al 2006). In comparison with finding for langurs in Thailand, the result we gained demonstrated that the silvered langur, Trachypithecus cristatus (2n=44) had NORs on autosome 15 which is the satellite chromosome (metacentric chromosomes) (Bigoni et al 1997).…”

Summary Localization of nucleolar organizer regions (NORs) of four gibbon species in Thailand was studied. Blood samples were taken from 1 male each of the following 3 species: white-handed gibbon (Hylobates lar), pileated gibbon (H. pileatus), and white-cheeked gibbon (Nomascus leucogenys): and 1 female of the dark-handed gibbon (H. agilis). These were subjected to standard whole blood T-lymphocyte culture. The samples were harvested by colchicine-hypotonic-fixation-air-drying technique and were followed by the Ag-NOR banding technique. The results showed that the H. lar had NORs on chromosome pair 13 (submetacentric chromosomes) while the H. agilis had NORs on chromosome pair 10 (submetacentric chromosomes) and H. pileatus had NORs on chromosome pair 15 (metacentric chromosomes). In addition, the N. leucogenys showed 5 positions with NORs on chromosomes pairs 23, 24 (acrocentric chromosomes) and the Y-chromosome (submetacentric chromosome). These results are useful to confirm marker chromosomes of gibbons and also comprise basic genetic information for these animals.
