Drivers of phage-encoded bacterial virulence gene profiles. nMDS analyses of a microbial abundances and b putative hosts as predictors of the relative abundances of viral genomes encoding bacterial virulence genes. Each virome is represented by a circle in the plot color-coded by the microbial abundance (Log10) in that reef site. The distances between the circles represent a two-dimensional reduction of the multi-dimensional analysis of pairwise distances calculated using Bray-Curtis dissimilarities. Permutational linear model tests showed that microbial abundance (A) was a significant predictor of virulence gene profiles (p = 0.001), while host was only significant at 90% confidence (p = 0.052)
