Chromosomal localization and genomic organization of cloned repetitive DNA fragments in mosquitoes (Diptera: Culicidae)
Autor(es)Kumar, A; Rai, KS
ResumoThe chromosomal localization and genomic organization of three cloned repetitive DNA fragments (viz., H-76, H-61, and H-19) isolated from the Aedes albopictus genome have been examined in Ae. albopictus and six other Aedes species: Ae. aegypti, Ae. seatoi, Ae. flavopictus, Ae. polynesiensis, Ae. alcasidi and Ae. katherinensis. The results from in situ and Southern hybridization analyses show that the sequences homologous to cloned repetitive DNA fragments are dispersed throughout the genome in each species. The sequences homologous to these cloned repetitive DNA fragments are also found in Haemagogus equinus, Tripteroides bambusa and Anopheles quadrimaculatus and are dispersed in their genomes. Data indicate divergence in the amount and the structural organization of sequences homologous to these cloned fragments among mosquito species.
