Contains Figure A, Reddening in the petiole of a young leaf 48h following insect damage to the older leaf below it.

White arrows point to petioles of young leaves where color differences were evident. Table A, Source leaf removal increases total phenolics in A. thaliana plants. Summary of 3-way ANOVA comparing total phenolics within two herbivore-damaged leaves and young, systemic leaves of intact A. thaliana rosettes or those with source leaves removed. Table B, Source leaf removal reduces anthocyanin accumulation in A. thaliana plants. Summary of 3-way ANOVA comparing anthocyanin accumulation within two herbivore-damaged leaves and young, systemic leaves of intact A. thaliana rosettes or those with source leaves removed. Table C, Source leaf removal does not influence flavonoid accumulation in A. thaliana plants. Summary of 3-way ANOVA comparing flavonoid accumulation within two herbivore-damaged leaves and young, systemic leaves of intact A. thaliana rosettes or those with source leaves removed. Table D, Middle-aged leaves of suc2-1 plants contain lower levels of total phenolic compounds relative to WT plants. Summary of 3-way ANOVA comparing total phenolics within two herbivore-damaged leaves and young, systemic leaves of wild-type (Ws-2) and mutant (suc2-1) lines. Table E, Middle-aged leaves of suc2-1 plants contain lower levels of anthocyanin relative to WT plants. Summary of 3-way ANOVA comparing anthocyanin accumulation within two herbivore-damaged leaves and young, systemic leaves of wild-type (Ws-2) and mutant (suc2-1) lines. Table F, Middle-aged leaves of suc2-1 plants contain lower levels of flavonoids relative to WT plants. Summary of 3-way ANOVA comparing flavonoid accumulation within two herbivore-damaged leaves and young, systemic leaves of wild-type (Ws-2) and mutant (suc2-1) lines. (PDF)
