Other claims from this paper (15)
- Observation A hydrogen peroxide burst occurred in tobacco lateral roots 20 days after inoculation.
- Intervention effect Exogenous H2O2 increased tobacco colonization by G.m.
- Intervention effect Ascorbic acid reduced colonization percentage.
- Intervention effect G.m colonization induced intense H2O2 fluorescence in tobacco roots.
- Intervention effect AsA decreased H2O2 fluorescence intensity in tobacco lateral roots.
- Intervention effect AsA decreased H2O2 fluorescence intensity in fungal hyphae.
- Intervention effect POD activity increased significantly in colonized tobacco lateral roots.
- Intervention effect SHAM decreased H2O2 fluorescence in tobacco lateral roots.
- Intervention effect DADD decreased H2O2 fluorescence in tobacco lateral roots.
- Intervention effect SHAM did not significantly affect fungal hyphal H2O2 fluorescence.
- Intervention effect DADD did not significantly affect fungal hyphal H2O2 fluorescence.
- Mechanism H2O2 may participate in tobacco-AM symbiosis.
- Mechanism Tobacco roots and fungal hyphae may both produce H2O2.
- Mechanism PAO and POD may participate in tobacco root H2O2 production.
- Mechanism Other H2O2 sources may exist in fungal hyphae.
