ABSTRACT: Pathogens are imminent threats to crop production.
Among the management tools available to protect crops from diseases, the use of
host-plant resistance had been hindered by a lack of tools and resources to
identify resistance genes (R-genes). Genomic technologies have empowered
acquisition of a new level and quality of information on plant-pathogen
interactions. Next generation sequencing, differential transcriptome analysis,
gene editing, and use of bioinformatics have
greatly expanded the numbers of R-genes identified, enriched
understanding of R-avirulence gene interactions, and disease diagnosis. In this
review, we highlight the application of genomic technologies to identification
of pathogen machinery for future improvement of host plant resistance.
