Other claims from this paper (12)
- Observation Incompatible CY25 inoculation produced two ROS peaks on days two and five.
- Observation Compatible CY29 inoculation produced one ROS peak on day six.
- Association Hypersensitive reaction in the incompatible interaction was associated with the early ROS burst.
- Mechanism The authors inferred that an early oxidative burst could mediate hypersensitive reaction.
- Observation Late ROS production in infected wheat leaves accompanied membrane damage, leakage and cell death.
- Mechanism The authors inferred that strong ROS could cause cell death.
- Observation Enzyme activity changes indicated H_2O_2 was the main early ROS component in incompatible interaction.
- Observation Enzyme activity changes indicated O-·_2 and H_2O_2 were late ROS components in both interaction types.
- Mechanism The authors suggested O-·_2 was responsible for cell death.
- Association Hypersensitive reaction was associated with increased cytosolic calcium in the cellular matrix.
- Association Declining cytosolic calcium could delay hypersensitive reaction.
- Mechanism The authors inferred that increased cytosolic calcium is necessary for hypersensitive cell death and serves as a defense messenger.
