Fig 5. Expression levels of selected genes from pathogenically infected midguts as analyzed by deep sequencing and validated by qRT-PCR.

Indicated is the fold change in expression of selected genes between persistent and pathogenic infection as obtained by qRT-PCR on 2^nd instar samples (qPCR-2) or by deep sequencing on both 2^nd and 4^th instar samples (DS-2 and DS-4, respectively). Selected genes belong to the group with highest difference in expression between persistent and pathogenic infection. Please note that fold changes are expressed as log2 values (a 2-fold up- or down-regulation corresponds to a log2 value of 1 or -1, respectively). See Table 2 for further explanation on gene identity and function.
