Comparison of the abilities of G13, G13-R, and G13-T to elicit extracellular alkalinization and H2O2 accumulation by suspension-cultured cv Xanthi cells

Compound EC50
Extracellular alkalinization H2O2 accumulation

G13 1.0 1.4
G13-R 1.6 1.9
G13-T 8.7a >8.7

Each of the oligogalacturonides was tested at five concentrations and the data were used to calculate the EC50 values.
