Distribution and features of previously-identified virulence genes. a, b Gene association for PA14 (a) and PAO1 (b) protein-coding gene loci. Gene loci are plotted against the association statistic (p value of MW test), shown as |log10(p value)|. Previously identified virulence genes are indicated with black dots and the top 5 most associated genes labeled. The top known genes associated with virulence are PA14_27690 and PA14_27700. Loci are also colored according to the directionality of the gene-virulence association (gray: positively associated; red: negatively associated; yellow: p value equals zero). Horizontal dashed lines demarcate a significance threshold (p < 0.01)
