| Outline of Final Research Achievements |
The epiphytic bacterial symbionts, Sphingomonas and Methylobacterium species inhabit in the phyllosphere without causing any harmful effect on plants. Sphingomonas species are known to protect plants against pathogenic bacteria. This study investigated how plants recognize Sphingomonas species, and the mechanism of antagonistic effect. Cells, flagella, and flagellin peptides from Sphingomonas species evoked immunity reactions in plants, suggesting the involvement of flagellin sensing in plants. It was also found that Sphingomonas species directly antagonize pathogenic bacteria by producing unknown substances that may be involved in iron acquisition.
