Pairwise P-acquisition vOTU-host linkages identified in this study. vOTUs are shown on the right-hand side of the panel and colored according to the kinds of P-acquisition AMGs that they encoded, while the hosts are shown on the left-hand side of the panel and colored according to their taxonomy. The number of linkages between individual vOTUs and their hosts are proportional to the sizes of those lines linking them. Detailed information of the P-acquisition vOTU-host linkages is provided in Supplementary Data 17 .
