Figure 4.

Transcriptome comparison among the rice leaves (Oryza sativa) inoculated by viruliferous small brown planthoppers (Laodelphax striatellus) or microinjected with Rice stripe virus (RSV) crude preparations from RSV‐infected rice seedlings or viruliferous small brown planthoppers. (a) Pearson correlation analysis of transcriptional profiles using the heatmap.2 function implemented in R package gplots. (b, c) Venn diagrams illustrating the number of upregulated (b) and downregulated genes (c) in the three treatments of rice leaves compared with their respective controls. Three biological replicates were sequenced for each group. Q, rice leaves fed on by viruliferous planthoppers; QC, rice leaves without planthopper infestation; I, rice leaves microinjected with insect‐derived RSV; IC, rice leaves microinjected with extracts of nonviruliferous planthoppers; P, rice leaves microinjected with plant‐derived RSV; PC, rice leaves microinjected with extracts of healthy plants.
