Spatiotemporal resolution of herbivory-regulated interactive motifs in gene expression. A, Time-response metrics, derived from bootstrap-based nonparametric ANOVA models for genes with tissue-specific responses to OS elicitation, were scaled and classified by BL-SOM. Red and pink clusters represent sets of genes showing up-regulation in treated leaves or down-regulation in unelicited tissues (roots or systemic leaves). Blue and pale blue clusters represent sets of genes showing up-regulation in unelicited systemic tissues (roots or systemic leaves) and down-regulation in elicited leaves. B, Each node in the grid represents a cluster of genes with similar amplitude of responses to simulated herbivory, defined as the product of the response metric with fold change differences between tissues that were compared. GO term enrichment for these motifs is presented in Supplemental Figure S4.
