Other claims from this paper (14)
- Association Isolate aggressiveness correlated with H2O2 and OH* in infected leaves.
- Observation Aggressive isolates induced OH* peaks within 24 h.
- Observation Aggressive isolates elevated H2O2 within 48 h.
- Observation Nonaggressive interactions showed no AOS increase.
- Intervention effect All fungal isolates suppressed plant peroxidase activity.
- Observation Aggressive isolates suppressed peroxidase more than nonaggressive isolates.
- Observation H2O2 production in infected leaf discs exceeded accumulation in medium.
- Intervention effect Catalase reduced infection severity.
- Intervention effect D-mannitol reduced infection severity.
- Observation Cellulases were secreted after infection began.
- Observation Xylanases were secreted after infection began.
- Observation All isolates produced PGs early in infection.
- Association PG production did not track aggressiveness.
- Mechanism Authors infer AOS might help necrotrophs kill host tissue early.
