Heat map for expression of 891 differentially expressed G. nigrifrons transcripts.

Differentially expressed transcripts were identified using one-way ANOVA (P<0.05; RPKM change >2). Each row represents an individual transcript; each column labeled 1–3 represent replicate samples of non-acquirers, acquirers, transmitters, or the healthy control, as outlined in the Methods. For each transcript (row), the relative expression level for each sample is represented by a color that reflects its z-score (shown in the redgreen key), calculated by subtracting the mean expression value for the row from the sample value and dividing by the standard deviation for the row.
