Figure 5: Incompatible heterografts have prolonged differential gene regulation compared to self-grafts.

Differentially expressed genes (>1.5 or <−1.5, p-value<0.05) of each grafted tissue (compared to ungrafted) at each time point for tomato and pepper. Upregulated genes are shown in light colors and downregulated genes are shown in dark colors. Self-grafted scions are dark purple, self-grated stocks are light purple, heterografted scions are orange, and heterograft stocks are yellow. Each combination has 3–5 bio-replicates.
