Chromosome analysis of Reba carp, Cirrhinus reba

Le résumé fourni par la source

Chromosome analysis is useful in different cytogenetics and genomics studies forvarious purposes e.g., linkage analysis, evolutionary studies and species identification andclassification. Metaphase squash method using colchicine has been used for long time primarilyfor identifying chromosome number for many fishes from larval stage. Although majority of theIndian major carps have undergone such investigation, Cirrhinus reba, an important minor carpof Bangladesh is yet to be investigated. We investigated into the chromosome number and aneffective concentration of colchicine solution along with duration of treatment in this study.Exposure to both 0.03% and 0.05 % colchicine for the duration of 6 and 4 h produced goodquality chromosome spreads. The chromosome number obtained in the diploid (2n) individuals inthis study was 50 which is very similar to other Cirrhinus species. The present results suggestbasic information of chromosome number on which furtherinvestigation including detailkaryotype analysis ofC. reba and other related fish species can be done for cytogenetic studies.
