FIG 1.

Inactivation of Tep2 and Tep4 modulates trehalose levels in Drosophila in the presence or absence of Photorhabdus infection. Trehalose levels (micrograms per milliliter) in tep2 (A and B) and tep4 (C and D) loss-of-function mutants are compared to those in the corresponding background control flies (w¹¹¹⁸ and yw, respectively) (n = 5) 6 and 18 h after infection with E. coli (Ec), P. luminescens (Pl), or P. asymbiotica (Pa) or injection with 1× PBS (negative control). The means from three independent experiments are shown, and error bars represent standard deviations. Significant differences are shown with asterisks (*, P < 0.05; **, P < 0.01).
