Comparative Genomics

Comparative Genomics

To infer gene functions across species, we have developed a highly accurate and computationally efficient method for large-scale application of high-throughput orthology predictions. The method contains three major steps: 1) all-against-all gene comparisons for every pair of genes, 2) pair-wise predictions for every two genomes, and 3) the generation of clusters that contain orthologous genes across multiple genomes. Our database currently contains predicted orthologs for over 900 bacterial genomes.
