Co-occurrence of microbial SVs in speargrasses rhizosheath-root system and bulk sand. Significant interaction (co-occurrence and mutual exclusion) between bacteria and fungi SVs in S. sabulicula, S. seelyae, C. spinosa, and bulk sand were visualized by co-occurrence network (upper panels). Circles (nodes) represent SVs (bacteria and fungi) significantly interacting in the microbial networks. Size of circles indicates the degree of connection. Nodes (SVs) were colored according to their taxonomic affiliation. Edges were colored by the taxonomic affiliation of their origin-node. Relative abundance (as counts per million, CPM) of all SVs significantly interacting in speargrass and bulk sand co-occurrence networks was visualized as a function of their degree of co-occurrence (lower panels). In the lower panel, hub SVs were colored in blue and keystone SVs are displayed in pink. Arrows indicated hubs (blue dot) and keystone SVs (pink dot) belonging to the Microvirga genus detected in the three plant networks. Keystone SV nodes were also indicated with a pink border in the co-occurrence network images (upper panels)
