Figure 9. Fold-induction of anthocyanin levels in the roots (black) and shoots (gray) of wild-type (WT), ein3 and jar1 seedlings that were either kept on the fungal lawn of P. indica or mock-treated. Nine-day-old seedlings were transferred from MS medium to a plate with KM without or with a fungal lawn for 7 d before the anthocyanin level was determined for the roots and shoots. The values indicate fold induction (A_{530+P. indica}/A_{530-P. indica}). For experimental details cf. Material and Methods. Based on 9 independent experiments with 20 seedlings each, bars represent SEs. Errors are the sum of the individual errors.
