Differential effects of the Imp-L2 host gene mutation on the survival-promoting effects of Lp and Ap. a The survival rate of WT GF larvae shows a slight decrease as the abundance of protein content in their diet is decreased. b The survival rate of Imp-L2 mutant GF larvae drastically decreases as the abundance of protein content in their diet is decreased. c Mono-association of WT GF larvae with either Lp (WJL), Ap (DM001), or P3G5 marginally increases their survival rate. d Mono-association of Imp-L2 mutant GF larvae with Lp (WJL) has no effect on their survival rate. Mono-association of Imp-L2 mutant GF larvae with Ap (DM001) dramatically increases their survival rate. Mono-association of Imp-L2 mutant GF larvae with P3G5 increases their survival rate in a manner similar to that shown by Ap (DM001). Values shown are obtained from more than three independent observations. *p < 0.05 and **p < 0.01 compared to values from GF larvae (t-test). n.s., not statistically significant. Error bars denote standard error of the mean (SEM)
