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).
