Identification of plant-parasitic nematode attractant

Scientists have purified and identified an attractant for crop-infecting root-knot nematodes from flaxseeds. Their experiments revealed that rhamnogalacturonan-I (RG-I), a flaxseed cell wall component, can attract root-knot nematodes. The linkages between rhamnose and L-galactose are essential for the attraction.
