CAD and infection: Comparing the transcription and proteomics data of the roots in susceptible NPB and resistant Khao Pahk Maw for the eight proteins/genes, clearly only ACX, CAD, GST and RPM1 showed opposite reactions in the susceptible and resistant rice lines that all of them were significantly down-regulated in susceptible NPB, whereas they were remarkably up-regulated in resistant Khao Pahk Maw, in response to the infection of M. graminicola (Figure 6A–C).
