With the advent of OMICs techniques, more and more OMICs data across different levels of biological molecular organization (such as the https://www.omicsonline.org/plant-pathology-microbiology.php, transcriptome, proteome, or metabolome) have been generated [1,2]. It makes the study of biological system or the interaction between biological systems practical. As biotic stress for plants, the influence of phytopathogen including pathogenic bacteria or fungi on plants has attracted more and more attention  considering their economic damage on crop yields. From the view of systems biology, many studies have been designed for the interpretation and modelling of host-pathogen interactions  to understand pathogenic and defensive mechanisms, however most of the studies have focused predominately on the host or the pathogen part.
In , the metabolic interplay between five pairs of plants and phytopathogens was studied by constructing their genome-scale metabolic networks and the pathogen dependent impairment effects on the plants’ metabolome was suggested. It provides insights into potential mechanisms of how phytopathogens exploit their host plants.
From the level of protein interaction, the interspecies proteinprotein interaction (PPI) network was constructed and exemplified in the study of Candida albicans-zebrafish interaction recently [6,7]. In their study, the simultaneously quantified time-course Candida albicans-zebrafish interaction transcriptomics and other OMICs data were used to reconstruct interspecies PPI network, and furthermore redox status was found critical in the battle between the host and pathogen. Other machine learning based computational methods were also designed to reconstruct the interspecies PPI between human T-cell leukemia viruses (HTLV)  or human immunodeficiency virus (HIV) [9,10] and Human. The similar concept could also been applied in the study of plant-phytopathogen interaction.
With recent advances in sequencing technologies, especially nextgeneration sequencing (NGS), metagenome has been applied in the study of host-pathogen interaction [11,12] from the perspective of community. Proteome technique have also been applied to study the host-pathogen interaction, for example, in , the secretome and extracellular proteome of potato late blight pathogen Phytophthora infestans was profiled and provided insights into secretion mechanisms for oomycetes.
