Proteins in the roots of NPB uniquely caused by infection of M. graminicola. (A–C) Specifically expressed proteins, up-regulated significantly differentially expressed proteins (SDEPs) and down-regulated SDEPs in the roots of NPB without infection of M. graminicola at 1, 3 and 7 days of growth, respectively (CK_versus_CK0). (D–F) Comparison of the proteins (all the specifically expressed proteins and up- and down-regulated SDEPs) in the roots of NPB between samples with and without infection of M. graminicola at 1, 3 and 7 dpi, respectively (MG_versus_CK and CK_versus_CK0). (G) All the unique proteins in the roots of NPB with infection of M. graminicola at 1, 3 and 7 dpi (the blue parts in (D–F)).
