Co-occurrence networks of healthy and diseased American ginseng in new and old ginseng fields. Networks were constructed using pairwise Spearman’s rank correlation coefficients at the genus level (Spearman’s rho > 0.9, P < 0.05). Node size is proportional to degree. Labels only displayed parts of nodes with LefSe biomarkers or degrees ≥ 5. Positive (red edges) and negative (blue edges) correlations between nodes are shown. a–d Represent ND, NH, OD and OH samples, respectively. ND new ginseng field with symptomatic American ginseng, NH new ginseng field with asymptomatic American ginseng, OD old ginseng field with symptomatic American ginseng, OH old ginseng field with asymptomatic American ginseng (color figure online)
