The Department of Energy (DOE) Joint Genome Institute (JGI) is a national user facility dedicated to advancing genomics for bioenergy and environmental applications. The JGI Genome Portal provides unified access to all JGI genomic databases and analytical tools, enabling users to track projects, access and analyze sequenced genomes, and explore and compare genomes of various organisms. The portal includes specialized resources such as Phytozome for plant genomes, MycoCosm for fungal genomics, and IMG for microbial genomes. MycoCosm, a new integrated fungal genomics resource, offers web-based genome analysis tools for diverse fungi, including a genome browser, BLAST, VISTA tools, and community annotation features. The portal is built on scalable infrastructure, with a majority of components developed using Java and open-source technologies, and supports over 25 TB of genomics data. Future plans include further scalability, integration, and development of new analytical tools to accommodate the increasing volume of sequenced genomes.The Department of Energy (DOE) Joint Genome Institute (JGI) is a national user facility dedicated to advancing genomics for bioenergy and environmental applications.
