Fig. 3.

Distribution of microbial functions with respect to plant phylogeny. Distributions are shown for the subset of Tier 3 microbial functions with phylogenetic signal (K statistic) in the top 5% of values, as compared to the expected distribution of phylogenetic signal according to the K statistic randomization test (P < 0.05). Symbol size indicates the scaled relative abundance of microbial functions for each host species
