[en] Plant-pathogen interactions have been performed extensively over the years from both plant and pathogen viewpoint. An overall understanding of how plant and pathogen recognize each other, and the differentiate to establish either a compatible or an incompatible relationship is crucial in this field of inverstigation. With transcriptomics approaches, we could successfully identify the defence-related genes expressed during phytopathogen infections. The plant-paghogen interactions and findings considering the wheat sharp eyespot, Rhizoctonia cerealis and transcriptomics were summeriszed in this paper. We also discussed these findings considering the advantages and limitations of current transcriptomic tool in plant-pathogen interactions.
