Figure 2. Stage- and tissue-specific expression of the P. xylostella P450s.

(a) Hierarchical clustering of the 85 PxP450s based on RPKM values from the digital gene expression profiling (DGE). The samples are described as in Figure 2a. The log2 RPKM values are presented with varying colors. The darker red represents higher expression values, and the gray in the heat map missing values. (b) qRT-PCR-based expression of 10 selected P. xylostella P450s across developmental stages of the susceptible strain.
