Impact of domestication and soil microbiome on plant trait-trait relationship
We found contrasting patterns of trait-trait relationships in network analysis as affected by both domestication and soil microbiome. Overall, we found a greater edge density (present edges to all possible edges within a trait network) for modern barley as compared to its wild counterpart (Fig. 4, Table 1). Next, the network diameter values were greater for modern barley than that for wild barley. We also found that the network diameter values increased for both barley species under DSM in comparison with NSM (Fig. 4). Similarly, the mean path distance between various traits was greater for modern barley and the path distance further increased under DSM for both barley species (Fig. 4, Table 1). The modularity of the network was much higher for wild barley as compared to the modern barley and the impacts of soil microbiome were less pronounced (Fig. 4).
