Pattens of the bacterial co-occurrence networks between diseased and healthy tobacco plants across four compartments. (A) Co-occurrence network analysis of diseased and healthy tobacco plants along the soil-root continuums. Nodes represent the dominant bacterial genera that are shown in different colors based on class taxonomy. The size of each node is proportional to the degree of the genus. Lines in red and green indicate positive and negative correlations, respectively. (B) Network topological parameters for bacterial networks in four niches. (C) The correlations between Ralstonia and other genera in diseased and healthy endosphere
