Bioinformatics has sparked a transformative shift in plant pathology in recent years. This interdisciplinary field has revolutionized the study of plant diseases by providing powerful tools for understanding complex molecular networks in pathogen-host interactions. Highthroughput sequencing and computational tools have replaced labor-intensive techniques, allowing rapid and accurate analysis of vast genomic datasets. These advancements have enhanced our understanding of pathogen diversity, evolution, and virulence factors, shedding light on previously unknown aspects of plant disease dynamics. Bioinformatics has also aided in developing targeted disease management strategies by identifying virulence factors, genetic markers, and novel resistance genes. This integration has opened new avenues for disease diagnosis, management, and crop breeding, improving global food security and economic stability.
