Figure 6

Correlation of the gene expression levels (FPKM) for all of the Musca domestica strains tested versus the ALHF pyrethroid-resistant strain (upper panels). Scatterplots represent the differential gene expression compared to the ALHF strain (lower panels). In the upper panels, the points closest to the 1:1 line represent genes with the same gene expression value as the ALHF strain and the tested M. domestica strain. In the lower panels, each point represents a gene, with red points below the central axis indicating the genes that were down-regulated in the tested M. domestica strain compared to the ALHF strain, thus the red points below the horizontal axis on the lower panels represent the genes that were up-regulated in the pyrethroid-resistant ALHF strain and putatively linked to insecticide resistance.
