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 | |
toCTR | μm | |
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.
The EC50 is determined based on the maximum response obtained with G13.
