Drosomycin transcripts were significantly increased in yw compared to chico flies at 24 h after infection with E. coli or P. luminescens (P < 0.01; Fig. 3e and P < 0.05; Fig. 3f); however, Drosomycin transcripts were significantly higher in Chico mutants than in control individuals (P < 0.05; Fig. 3e). This evidence concerns the gene TLE7 and infection.
