FISH digital imaging microscopy in mosquito genomics.
The yellow fever mosquito, Aedes aegypti, transmits pathogens that affect both humans and livestock, and has been the focus of extensive research to identify genetic loci that may be useful in control strategies. Fluorescence in situ hybridization (FISH) and digital imaging microscopy have provided a rapid mechanism to populate the physical map with probes derived from genetic markers, cDNAs and recombinant genomic libraries. When the physical and genetic linkage maps are aligned, map-based cloning will allow the rapid isolation of target genomic sequences. The strategy of FISH mapping and the results of initial hybridization studies are reviewed here by Martin Ferguson, Susan Brown and Dennis Knudson. An Ae. aegypti-specific genomic database, which collates data from mapping studies, sequences, references and other relevant information, is also discussed.
