| Popis: | The release of H2O2 by plant cell suspensions elicited with crude hyphal wall preparations has been studied in a complex of plant genotypes (two cvs ofCapsicum annuum and one of C.frutescens) and fungus species(Phytophthora capsici, Ph. parasitica andVerticillium dahliae), representing several combinations of compatibility and both host and nonhost resistance. Production of H2O2 was revealed as peroxidasedependent and catalase-inhibited fluorescence quenching of an extracellular probe (Pyranine). |
