The use of Next Generation Sequencing (NGS) in the study of plant and animal microbiomes is transforming our understanding of the intricate relationships between microbes and their hosts, with profound implications for agriculture, ecology, and conservation. Genomic techniques enable the detailed characterization of microbial communities associated with plants and animals, shedding light on the roles these microorganisms play in nutrient uptake, disease resistance, stress tolerance, and overall health. In agriculture, this knowledge facilitates the development of innovative strategies to enhance crop resilience, improve soil health, and reduce dependency on chemical inputs. In animal health, understanding the microbiome offers pathways to improve disease resistance, productivity, and well-being. Furthermore, genomics-driven insights into the microbiomes of wild plant and animal populations contribute to conservation efforts, helping to maintain ecosystem balance and resilience. By leveraging the power of genomics, scientists and practitioners are unlocking the potential of microbiomes to support sustainable agricultural practices and conservation strategies, ultimately fostering a more resilient and productive environment.
