| Outline of Final Research Achievements |
Due to the accident at the Fukushima Daiichi nuclear power plant, large amounts of 137Cs have been released into the atmosphere. Generally, root endophytes enhance environmental stress in plants. We evaluated the effect of 137Cs on the symbiosis between C. barvinervis and root endophytes, which enhance heavy-metal tolerance of the plant, analyzing the effect of 137Cs on isolation frequency of endophytes and their chemical characteristics. nMDS analysis showed that the isolation frequency was influenced by 137Cs concentration in soil. In contrast, GLMM analysis clarified that the isolation frequency of each species was not significantly influenced by 137Cs. GLMM analysis also clarified that Zn detoxicants or melanin productions by several endophytes showed significantly positive correlation with 137Cs concentration. We conclude that 137Cs would not remarkably influence symbiosis between C. barbinervis and root endophytes under heavy-metal stress.
