Table 1. Summary of metabolic changes occurring during light-induced rapid systemic signaling in Arabidopsis.

Metabolites significantly altered at P < 0.05 (ANOVA followed by Dunnett’s test and/or Student’s t test) are shown. The metabolic changes are divided based on their overall response patterns. Response patterns in rbohD mutants are indicated in the right column.
