Transcriptional profiles of the 1,046 and 536 G. nigrifrons transcripts with a significant treatment effect at 4 h and 7 d, respectively. Both analyses are based on one-way ANOVA with P-level significance at 0.05 and RPKM change >2. Each row represents an individual transcript; each column labeled 1–4 represents a replicate sample that was fed on healthy (control) or virus-infected (MCDV or MFSV) maize. For each transcript (row), the relative expression level in each sample (column) is represented by a color that reflects its row z-score (shown in the grayscale key), calculated by subtracting the mean expression value for the row from individual sample values and dividing by the standard deviation of the row.
