Microbial interkingdom association networks under drought stress. a Interkingdom co-occurrence networks of drought-resistant and drought-susceptible cultivars at YL and SQ sites. Only compositionality-robust (|ρ|> 0.8) and statistically significant (P < 0.05) correlations are shown. The size of each node indicates the relative abundance of the corresponding amplicon sequence variant (ASV). Blue solid lines represent co-presence associations, and gray dotted lines represent mutual exclusion correlations. The thickness of each line is proportional to the correlation coefficient of the corresponding association. b Bar graph showing the proportion of edges in bacterial–bacterial (BB), bacterial–fungal (BF), and fungal–fungal (FF) correlations in the different samples. c Average numbers of neighbors, edges, and shortest paths in the different samples. d Scatter plot showing the features of degree and closeness centrality for the different wheat cultivars. e Degree and interaction type of the top seven hub nodes in the drought-resistant and drought-susceptible cultivars
