Molecular plant pathology translates the enormous strides in molecular biology into understanding and controlling plant diseases at a molecular level. It is built on the understanding of the interactions between the plants and pathogens, such as bacteria, fungi, viruses, and nematodes, which subsequently gives the proper management strategies for diseases.

Some of the major areas include pathogen biology, host-pathogen interaction, and mechanisms of disease resistance. Techniques applied include mode of infection of plants by pathogens, evasion of the plant immune system, and mechanisms of disease. Gene sequencing, molecular cloning, and proteomics investigate these interactions and identify the key factors that cause the development of disease.

Understanding the interaction between the plant and the pathogen at the molecular level could identify the mechanism of disease resistance. This developed the possibility of design of the genetically modified crops with better resistance to diseases through the research on the plant genes conferring resistances to pathogens. Molecular markers breeding, which is engaged in both traditional and advanced approaches, is also included in this method.

Molecular plant pathology is developed for the evolution of methods of diagnostics that would be used for early detection and tracking of diseases. The techniques like PCR and RNA sequencing are helpful in identifying pathogens and characterizing their genetics so that interventions can happen more accurately and in real time.
