Vertebrate genome sequencing: building a backbone for comparative genomics.
The human genome sequence provides a reference point from which we can compare ourselves with other organisms. Interspecies comparison is a powerful tool for inferring function from genomic sequence and could ultimately lead to the discovery of what makes humans unique. To date, most comparative sequencing has focused on pair-wise comparisons between human and a limited number of other vertebrates, such as mouse. Targeted approaches now exist for mapping and sequencing vertebrate bacterial artificial chromosomes (BACs) from numerous species, allowing rapid and detailed molecular and phylogenetic investigation of multi-megabase loci. Such targeted sequencing is complementary to current whole-genome sequencing projects, and would benefit greatly from the creation of BAC libraries from a diverse range of vertebrates.
