Other claims from this paper (6)
- Intervention effect The pathogen elicited H2O2 production in resistant Ulmus pumila cell cultures.
- Intervention effect Susceptible U. campestris cultures did not show that H2O2 response.
- Observation H2O2 production began 30-40 min after inoculation, peaked at 4-6 h, and persisted to 24 h.
- Intervention effect Added H2O2 did not accumulate mansonones or scopoletin.
- Intervention effect H2O2 significantly delayed fungal spore germination and growth.
- Mechanism The authors suggest induced H2O2 production contributes to resistance by delaying early pathogen growth.
