Omics approaches have revolutionized the understanding of plant-microbe interactions, which are crucial for ecosystem dynamics and sustainable agriculture. These interactions are influenced by factors such as host characteristics, environmental conditions, and human activities. Omics technologies, including genomics, transcriptomics, proteomics, and metabolomics, provide a comprehensive view of these interactions by elucidating genetic, molecular, and biochemical mechanisms. Genomics identifies key genes, transcriptomics reveals gene expression dynamics, proteomics identifies essential proteins, and metabolomics profiles small molecules, offering a holistic perspective. This review synthesizes diverse microbial-plant interactions, showcasing the application of omics in understanding mechanisms such as nitrogen fixation, systemic resistance induction, mycorrhizal association, and pathogen-host interactions. Despite challenges in data integration and ethical considerations, omics approaches promise advancements in precision intervention and resilient agricultural practices. Future research should address data integration challenges, enhance omics technology resolution, explore epigenomics, and understand plant-microbe dynamics under diverse conditions. Omics technologies hold immense promise for optimizing agricultural strategies and fortifying resilient plant-microbe alliances, paving the way for sustainable agriculture and environmental stewardship. The integration of multi-omics data and modern web-based tools enables comprehensive insights into plant-microbe interactions, facilitating the development of innovative agricultural practices and sustainable solutions. Challenges such as data standardization, computational complexity, and ethical considerations remain, but continued advancements in omics methodologies and interdisciplinary collaborations hold promise for overcoming these challenges and further enhancing our understanding of plant-microbe interactions for sustainable agriculture and environmental stewardship.Omics approaches have revolutionized the understanding of plant-microbe interactions, which are crucial for ecosystem dynamics and sustainable agriculture.
