Growth profiles of selected single-gene knockouts.

<p>Growth profiles of <i>ΔnuoCD</i> (A), <i>ΔnuoF</i> (B), <i>ΔnuoI</i> (C), <i>Δndh</i> (D), <i>ΔcyoB</i> (E) and <i>ΔcyoD</i> (F) transformed with p11, pRV or pR_K52QV plasmids as indicated. To account for the inherent differences in growth rates among the knockouts that are independent of the effects of RavA and ViaA, all growth data collected in the presence of kanamycin were normalized by the corresponding data collected in the absence of the antibiotic.
