The altered metabolome induced by PA treatment impairs M. incognita motility
As PA treatment significantly alters the plant metabolome and reduces tomato susceptibility to M. incognita , we wondered whether exposure to a methanol extract from PA- and mock-treated plants would differentially affect the motility of M. incognita J2s. AsFigure 7 shows, shoot extracts from PA-treated plants are more nematistatic than shoot extracts from mock-treated plants after 4 and 24 hours of exposure (4 h: P < 0.001; 24 h: P < 0.001), while root extracts from PA-treated plants are more nematistatic only at 24 hours (4 h: P = 0.098; 24 h: P < 0.001).
