From: Identification of the Weevil immune genes and their expression in the bacteriome tissue
Analysis of immune gene expression in aposymbiotic larvae challenged with Sitophilus zeamais primary endosymbiont. Transcript of genes induced by an E. coli challenge were quantitated by qRT-PCR in untreated aposymbiotic larvae (control) and in larvae six hours after a 69 μl injection of either sterile water (sterile) or SZPE cells (heat-killed or viable) obtained from 50 bacteriomes dissected from symbiotic fourth-instar larvae. ESTs were classified according to sequence similarity as in Table 2. Each bar represents the mean of three independent measurements with standard error.
