Table 2. Pathways of identified metabolites
differentially accumulated locally or systemically upon OG treatment in
leaves or roots. The percentage of signals showing significantly higher
accumulation from the total identified signals for a given treatment is
shown in brackets. Identified metabolites were assigned to their
corresponding metabolic pathways, and the number in the right refers to
the identified compounds within that pathway. The signals corresponding
to different treatments were compared using the non-parametric
Kruskal-Wallis test, and only data with a p-value<0.01 between
groups were used for subsequent identification.
