Fig. 4.—

Genome positions of colocalized poultry-associated genes and recombination regions. (a) Poultry-associated genes (blue) and recombination regions (red) mapped to the ED98 reference chromosome. Hot spots of colocalization of poultry-associated elements are numbered. (b) Schematic diagrams of each hot spot showing gene content, including poultry-associated genes and genes containing recombination regions. Genes with no poultry-association in the same regions are also shown (grey). Poultry-associated genes and genes containing recombination regions are labeled, including S. aureus pathogenicity island genes (1), transposon-related genes (2), hypothetical proteins (3), and phage-related genes (4). More details of putative gene function can be found in supplementary table S2, Supplementary Material online.
