Figure 4

Scatter plot of results of DNA microarray analysis of transcriptional response of diploid versus triploid Chinook salmon 18 h after a live Vibrio anguillarum challenge. Intensity dependent Z-scores were calculated using a sliding window and Z-scores above 2.0 (approximately 95% confidence interval) are in red, from 1.0 to 2.0 in green, and from 0.0 to 1.0 in blue. Circled points are the genes that were consistently differentially expressed in diploid relative to triploid challenged fish across seven microarray replicates. The putative function and 3N:2N transcription ratios for the twelve genes are given in Table 2.
