Transcriptome Comparison Reveals Distinct Selection Patterns in Domesticated and Wild Agave Species, the Important CAM Plants

Figure 5

In silico expression pattern of positive selection (PS) unigenes in Agave leaves. Rows and columns in heat maps represent genes and Agave species. Species name of A. deserti (AD), A. tequilana (AT), and A. sisalana (AS) is shown under the heat maps. The colour bar at the top indicates the degree of expression: red—low expression; green—high expression.
