Fig. 2: P-acquisition auxiliary metabolism genes (AMGs) identified in this study.

a Numbers of the AMGs involved in inorganic P solubilization, organic P mineralization, P transportation, and P starvation response regulation, respectively. The numbers of each kind of AMGs recovered from individual habitat types are indicated by different colors. Detailed information on the AMGs is provided in Supplementary Data 7. b A graph illustrating the increase in gene kind after adding the AMGs identified in this study (orange) to those reported previously (gray; detailed information on them is provided in Supplementary Data 9). c Genome organization diagrams of four representative vOTUs identified in this study (i.e., vOTU54, vOTU22, vOTU47, and vOTU24) and three representative public isolated phage genomes (i.e., GCA_002606105.1, GCA_004016045.1, and GCA_002956935.1). Due to the large genome size of GCA_002956935.1, only 30 genes upstream and downstream of the pstBACS cluster are displayed. Predicted open reading frames are colored according to VIBRANT and DRAM-v annotation functions. VOG, virus orthologous groups. Detail information on these viral genomes is listed in Supplementary Data 5, 6, 11.
