The constant interactions between plants and pathogens in the environment and the resulting outcomes are of significant importance for agriculture and agricultural scientists. Disease resistance genes in plant cultivars can break down in the field due to the evolution of pathogens under high selection pressure. Thus, protection of crop plants against pathogens is a continuous arms race. Like any other crop plants, legumes are also susceptible to many pathogens. The dawn of the genomic era with high-throughput and cost-effective genomic tools has revolutionized our understanding of the complex interactions between legumes and pathogens. The genomic tools have enabled a global view of transcriptome changes during these interactions that identified several key players in both the resistant and susceptible interactions. This review summarizes some of the large-scale genomic studies that comprehend the host transcriptional changes during interactions between legumes and their plant pathogens while highlighting some of the molecular breeding tools that are available to introgress the traits into breeding programs. These studies provide valuable insights into the molecular basis of different levels of host defenses in resistant and susceptible interactions.
