Figure 4

Metabolome changes in the shoots of two Broccoli cultivars, Coronado and Malibu upon root treatment by P. fluorescens SS101 or its cysH mutant 20H12. Shown are the results of the PCA (a) and HCA (b) based on differentially regulated semi-polar metabolites. In the HCA, various metabolite clusters are indicated by different colors; when none of the metabolites in a given cluster was annotated, the cluster number was omitted (clusters 3, 6, 8, 9, 12, 13, and 14 in panel b). * GLS, glucosinolate; ** d, derivative.
