Plant diseases pose a significant threat to global agriculture and food security. The ongoing battle between pathogens and plants has spurred continuous research efforts to develop effective strategies for enhancing plant disease resistance. This comprehensive review aims to shed light on the latest insights from the field of Molecular Plant Pathology and its contributions to the development of innovative strategies for bolstering plant immunity against a myriad of pathogens. Our review encompasses a thorough examination of the molecular mechanisms underlying plant-pathogen interactions, emphasizing key concepts such as the gene-for-gene hypothesis, effector-triggered immunity, and systemic acquired resistance. Furthermore, we delve into the realm of genetic engineering, showcasing examples of successful genome modifications that have conferred enhanced resistance to diseases in various crop species. In addition to genetic engineering, we explore the remarkable role of plant-associated microbiomes in bolstering disease resistance. We examine the intricate symbiotic relationships that exist between plants and beneficial microbes and discuss how harnessing these interactions holds immense promise for sustainable agriculture.
