Carbon source utilization trait associations form communities within the network that contain traits with similar structures and/or properties. a Network of positive associations among carbon utilization traits. The width of the edge between nodes represents the strength of the association between carbon sources. Node color represents similar molecular structures among compounds, and shading behind nodes represents significant communities within the network. Each subnetwork is labeled with a description of the biochemical structures or pathways captured by that subnetwork. b, c Reproduction of network highlighting compounds containing specific monosaccharide moieties. di Reproduction of network highlighting negative (red) and positive (blue) associations with the fermentation of specific sugars. Note that fermentation of a specific sugar is always positively associated with utilization of that sugar because utilization is a prerequisite for fermentation; in some cases, related sugars are also positively correlated. Trehalose fermentation may be an exception to the general trend of negative associations with other carbon sources because many yeasts synthesize trehalose internally [74]
