Figure 5.

The topological characteristics of phenylpropanoid and flavonoid pathways. Graphs were generated from Metabolomics Pathway Analysis using MetPA. (A) Phenylpropanoid pathway map displaying some of the OPLS-DA selected metabolites, altered in response to C. sublineolum infection. (B) Flavonoid pathway map showing OPLS-DA selected metabolites altered during sorghum responses to C. sublineolum infection. (^*) indicate overlapping points where metabolic pathways interconnect. Due to the limitation of the MetPA tool (considering the database used and search algorithm) not all metabolites that were chemometrically extracted (Table 2) could be mapped in the constructed pathway graphs.
