We have now entered in the post-genomic era, where we have knowledge of plethora of fungal genomes and cutting edge technology is available to study global mRNA, protein and metabolite profiles. These so-called 'omic' technologies (transcriptomics, proteomics and metabolomics) provide the possibility to characterize plant-pathogen interactions and pathogenesis at molecular level. This article provides an overview of transcriptomics and its applications in fungal plant pathology.
