FIG 1.

Distribution of genes significantly impacting bacterial fitness in a rich liquid medium. (A) Number of genes predicted to be essential, domain essential (only insertions in part of the gene lead to abundance decrease), or nonessential by the EL-ARTIST pipeline. (B) Principal-component analysis (PCA) of essential and nonessential genes of B. vietnamiensis (Bv) and P. kururiensis (Pk) in a rich liquid medium. The genes were classified according to their COG categories and the PCA was built in regard to the abundance of these categories.
