Relative amount of Portiera and Hamiltonella (normalized to the host nuclear β-actin gene) in H+ (black bars) and H− Q (red bars) whiteflies (B. tabaci) as determined by q-PCR.
Vertical lines indicate standard deviations of the mean. The asterisk indicates that symbiont gene expression differed (P < 0.001) between H+ and H− Q and n.s. indicates not significant (P > 0.05).
