AMP expression levels in the TmRelish-knockdown Tenebrio molitor larval fat body upon Escherichia coli (Ec), Staphylococcus aureus (Sa), and Candida albicans (Ca) infection. Healthy larvae (10th–12th instar) were injected with dsTmRelish and infected with a suspension of E. coli, S. aureus, or C. albicans on the third day, post-dsRNA injection. PBS-injected larvae were used as controls. After 24 h, the fat body tissue was dissected. Expression level of the AMP genes TmTenecin-1 (A), TmTenecin-2 (B), TmTenecin-3 (C), TmTenecin-4 (D), TmDefensin1 (E), TmDefensin2 (F), TmCecropin-2 (G), TmColeoptericin-1 (H), TmColeoptericin-2 (I), TmAttacin1a (J), TmAttacin-1b (K), TmAttacin-2 (L), TmThaumatin-like protein-1 (M), and TmThaumatin-like protein-2 (N) was measured using qRT-PCR and compared with the dsEGFP-treated groups. dsEGFP was used as a negative control and TmL27a as an internal control. The numbers above the bars indicate AMP expression levels. All experiments were repeated thrice, with similar results. Statistical analysis was performed using Student’s t-test (p < 0.05); ns: not significant.
