Gut bacteria accelerate mortality of P. versicolora in dsRNA-mediated environmental RNAi. a and c Kaplan–Meier survival curves of axenic and non-axenic larvae after feeding with dsSrp54k (a) and dsActin (c) (n = 30/group, shown is one representative experiment of four repeats). Srp54k (b) and Actin (d) relative expression in axenic and non-axenic larvae fed with dsSrp54k and dsActin (n = 5). Gene expression levels were set as one in larvae fed with dsGFP control. Kaplan–Meier survival curve was analyzed by the log-rank test. Gene expression differences between two groups were calculated using the independent samples t test. Data are presented as mean ± SE, ^*** P < 0.001; ^** P < 0.01; different letters indicate significant difference (P < 0.05)
