The molecular mechanisms of plantpathogen interactions have been a longtime hotspot of plant pathology. Recently, functional genomic strategies, including proteomics and transcriptomics, have been widely used in defining gene and protein function and expression profiles. Proteomics, a complementary research content of transcriptomics, has been a powerful tool to systematically analyze the cellular protein expression profiles and posttranslational modifications under pathogen invasion. Rice, a monocotyledonous plant for which the entire genome was completely sequenced, has been adopted as an ideal model for studying the molecular mechanisms of plantpathogen interactions. In this review, the main research techniques of proteomics, recent advances in proteomic analyses of rice under bacteria, fungi and viruses invasion were highlighted, and an overview on phosphoproteomics analyses of ricepathogen interactions was presented.
