Title

Other claims from this paper (7)
- Intervention effect SNP pretreatment suppressed Botrytis cinerea infection development in Arabidopsis leaves.
- Intervention effect SNP dose levels had no direct toxic impact on pathogen development.
- Intervention effect Exogenous NO restrained ROS generation, especially H2O2, during pathogen interaction.
- Association Inhibition of the oxidant burst coincided with delayed infection development in NO-supplied leaves.
- Observation SOD activity was unchanged in the studied leaves.
- Mechanism The authors suggest higher POD and CAT activities probably lowered H2O2 content.
- Mechanism The authors suggest NO may trigger enzyme activity that restrains H2O2 and leads to Botrytis resistance.
