High‐resolution cytogenetic map for the African malaria vector Anopheles gambiae

Year: 2010

Type: article

Abstract: Cytogenetic and physical maps are indispensible for precise assembly of genome sequences, functional characterization of chromosomal regions, and population genetic and taxonomic studies. We have created a new cytogenetic map for Anopheles gambiae by using a high-pressure squash technique that increases overall band clarity. To link chromosomal regions to the genome sequence, we attached genome coordinates, based on 302 markers of bacterial artificial chromosome, cDNA clones, and PCR-amplified gene fragments, to the chromosomal bands and interbands at approximately a 0.5-1 Mb interval. In addition, we placed the breakpoints of seven common polymorphic inversions on the map and described the chromosomal landmarks for the arm and inversion identification. The map's increased resolution can be used to further enhance physical mapping, improve genome assembly, and stimulate epigenomic studies of malaria vectors.
