Co-occurrence and mutual exclusion relationships among seed-associated microbiota of alpine plants. Network was prepared by combining taxonomic assignment to OTUs on species level of 16S rRNA and ITS amplicon dataset. Only significant interactions are shown (q ≥ 0.0004). Color of nodes represent the three taxonomic groups (blue: bacteria, yellow: fungi, pink: archaea), and the size of nodes is proportional to the abundance of the taxon. Color of edges indicates the type of the interaction (green: positive or co-occurrence, red: negative or mutual exclusion), and the edge width is proportional to the significance. Taxonomy for high-abundant taxa is included
