Outline of Final Research Achievements

Plant parasitic-nematodes threat agricultural crops by infecting the host plant root. The infective juvenile of the nematodes in the soil can locate the host plant root in some unrevealed way to find the most suitable point for infection. It is speculated that host-root-derived bioactive compounds called “attractants” plays a pivotal role in the infective stage of the nematodes.
We established the bioassay method to evaluate the bioactivity of the attractants and found that a liquid culture of a bacterium isolated from the hydroponic culture of a host plant showed strong attraction activity against root-knot nematode. We performed purification of the attractant in the culture supernatant and purified an active compound, elucidated its structure by following NMR analysis.
