GDL suppresses termite antimicrobial defense. (A) Effect of gain or loss of tGNBP-2 function on termites infected with Metarhizium anisopliae along the course of 12 days (GDL, d-δ-gluconolactone; mean of 2 groups, n = 12/group; *, P < 0.05 tGNBP-2 treated conidia vs. other groups, P < 0.05 GDL treated termites with untreated conidia vs. other groups, n.s. no significant difference vs. no infection). (B) Postmortem analysis of dead termites from GDL treatment groups representing percentage of termites confirmed to have been infected by microbial pathogens. Numbers above bars represent daily death count.
