Summary of C. lectularius transcriptome. (A) Distribution of reference contigs (blue bars), supercontigs (red bars), and contigs (green bars) after assembly using CD Minimus. (B) Ortholog hit ratio (OHR) for assembled ESTs (Aphis pisum- blue bars, Pediculus humanus corporis- red bars; Anopheles gambiae-green bars; Apis mellifera-purple bars). An OHR of one indicates a fully assembled sequence whereas a value closer to zero suggests a poorly assembled sequence. Nearly half of the ESTs had an OHR more than 0.5.
