| Outline of Final Research Achievements |
In this project, the mechanisms how the infective juveniles of the root-knot nematode (Meloidogyne incognita) are able to find the root tips of the host plants in soil were investigated. We found several isolates which can attract the nematodes by the screening of soil microbiome and elucidated the mechanism of the attraction. We also discovered that a part of the nematode-attracting bacteria proliferated in the rhizosphere of the host plant by using metagenomic analysis. These data indicate the novel attraction mechanism based on the interaction between host plants, bacteria, and nematodes.
