Figure 3.

Coexpression relationships of genes comprising PKPP1. Red nodes indicate up-regulated genes; green nodes denote genes that are repressed by Pi deficiency. Round-shaped nodes represent protein kinase genes, rectangles indicate protein phosphatase genes. This network can be divided into two sub-clusters A and B. Green stars indicates root hair-related genes.
