Other claims from this paper (14)
- Intervention effect Light reduced chlorophyll degradation during Pst infection relative to darkness.
- Intervention effect Light reduced the decline in photosynthetic function during Pst infection.
- Observation PSII maximal quantum yield declined as infection progressed.
- Observation PSI complex activity declined as infection progressed.
- Intervention effect Light reduced postinfection damage to PSI and PSII relative to darkness.
- Intervention effect Pst was 17-fold more abundant in tobacco leaves in darkness at 3 dpi.
- Observation Infection under light caused high H2O2 accumulation.
- Intervention effect H2O2 pretreatment alleviated chlorotic lesions in darkness.
- Intervention effect H2O2 pretreatment decreased Pst abundance in darkness at 3 dpi.
- Intervention effect MV pretreatment alleviated lesions and decreased Pst abundance in light.
- Intervention effect DCMU pretreatment aggravated chlorotic lesions.
- Intervention effect DCMU pretreatment increased the Pst population.
- Association Chlorotic symptoms and bacterial population size were negatively correlated with H2O2 accumulation.
- Mechanism The authors infer that light suppresses Pst through H2O2 accumulation.
