Figure 4.

Differences in mean number of VFs in OTUs enriched in each exudate treatment and ambient waters based on genomes of most closely related cultured isolates. Data are listed in Table 5; whiskers are one s.e. of the mean. Representative genomes ranged from 84% to 90% 16S sequence identity to OTUs, and statistical analysis is robust when a 90% minimum identity cutoff was applied. Note that Amansia and Halimeda exudates were combined to allow testing (n<3 each). Mean numbers of VFs in ambient waters are significantly lower than all three exudates, and Porites is significantly lower than Turbinaria (treatments with same letter are not significantly different, Tukey's post hoc test α=0.05).
