Figure 3.

Phylogenetic analysis of the co-expression networks. (A) Depicted are relationships among the lineages of plants. Estimated dates for some nodes are shown in millions of years before the present date. Major events are demarcated by black nodes and arrows. (B) Gene family consensus network depicting first appearance of the conserved families. Blue, orange, and green represent appearance in charophytes, mosses, and monocots and eudicots, respectively. Square and round nodes represent families present in four and three of the networks, respectively.
