Outline of Final Research Achievements

Chemoattractant for Ralstonia solanacearum contained in the root exudates of tomato was isolated using Sep-Pak C-18, activated carbon, Diol silica gel and NH2 silica gel columns. Chemoattractant is presumed to be a compound containing sugar as a component from the color reaction.
There have been few studies comparing the chemotattractant activity of root exudates of plants. We prepared root exudates of 9 plant species and investigated their chemoattractant activity. Among them, the root exudates of black gram showed strong activity. The active substance produced by black gram is similar to that of tomato, but it is considered to be a different substance.
