Figure 4
Changes in Cabernet Sauvignon metabolite interactions as a result of water deficit. Nodes correspond to primary (circles) and secondary (squares) metabolites; node colors correspond to compound classes as detailed in the figure legend. Edges between nodes represent correlations identified as significant at r ≥ 0.9 and q ≤ 0.01, where blue edges correspond to the irrigated treatment and red edges correspond to the water deficit treatment. Nodes are ordered into modules corresponding to their compound classes.
