Outline of Final Research Achievements

We took rhizosphere soil samples of Japanese black pine at Tsunami-damaged coastal forests in Tohoku region. The soil pH was rather high especially in the surface layer, but no severe heavy-metal contamination was detected. The ectomycorrhizal flora reflected the effect of disturbance due to Tsunami, represented by Wilcoxina spp.
For development of pine seedling propagation by means of functional microbes, screening of rhizobacteria was performed with the model plant Arabidopsis thaliana and Japanese black pine. Out of 152 rhizobacteria derived from coastal pine forests, Burkholderia spp. and Leifsonia sp. showed a significant effect to increase root branching in both plants.
