Figure 4

Heat-map diagram showing the five clusters of differentially expressed genes following HWB treatment. (A) Plots of the expression profiles of 1,225 differentially expressed genes. Gray lines mark the various gene profiles; the green, red, blue, pink and light-blue lines represent the average expression profiles of clusters 1–5, respectively. (B) Heat map showing relative expression of 1,225 fruit genes at the four sampling times (0, 4, 17 and 48 h). Color key represents relative expression on a log 2 scale.
