MAPK8 and infection: As expected, overactivation of this cascade by silencing puc (Figure S2), a phosphatase that normally suppresses JNK signaling, had the opposite effect and greatly reduced the intensity (Figure 1D, Table S3) (p<0.001; KS test) and the prevalence of infection from 68% to 41% (p<0.005; chi-squared [χ2] test).
