Figure 2

A comparison of CEP gene (A) and CEP domain (B) sequence diversity between seed plant families. These density plots of sequence diversity graph the distributions of pairwise genetic distances of CEP genes and domains within a single organism, aggregated by plant family. Genetic distances were calculated based on the AA sequences, using a maximum likelihood estimation. Tukey’s test reveals that both CEP gene and domain sequence diversity is significantly greater in all angiosperm families than in the gymnosperm family Pinaceae (P < 0.001). Additionally, the CEP gene and domain sequence diversity of Poaceae and Solanaceae are significantly (P < 0.05) greater than in other angiosperm families.
