| Research Abstract |
We selected a species of the dark septate endophytic fungus (DSE), Veronaeopsis simplex, which promotes the growth of host plant even under the stressed conditions. Interestingly, the presence of bacterial communities living outside and inside mycelium of the fungus was revealed. We showed that the DSE has a complex interaction with associated bacteria involving host plant playing a role in growth promotion and environmental stress tolerance.
With regards to the Cs accumulation, it varied with the host plant considered. In Chinese cabbage, the DSE inoculation caused higher Cs accumulation in above ground plant parts, whereas in tomato, Cs accumulation decreased significantly with the isolate tested, suggesting low-risk transfer on the food chain as a result of high and negative plant reactions rather than high and positive reactions as it is the case with Chinese cabbage.
