globalamfungi

GlobalAMFungi aggregates millions of arbuscular mycorrhizal fungal amplicon DNA sequence observations from high-throughput sequencing metabarcoding studies to map the global distribution and diversity of these plant symbionts.

Key Features:

• Comprehensive sequence compilation: The database contains almost 50 million observations of Glomeromycotinian AM fungal amplicon DNA sequences across almost 8500 samples with geographical locations and additional metadata obtained from 100 original studies.
• Multiple marker region support: The database includes sequencing data from three AM fungal taxon barcoding regions: the small subunit rRNA (SSU) gene, the internal transcribed spacer 2 (ITS2) region, and the large subunit rRNA (LSU) gene.
• Community-driven updates: The database is designed as a permanent effort that will be continuously updated by its creators and through scientific community collaboration.
• Rich metadata integration: The database compiles geographically referenced environmental samples with metadata on sampling location and environmental context.

Scientific Applications:

• AM fungal biogeography: The dataset enables research into patterns of AM fungal distribution across global scales and the environmental factors that drive those patterns.
• AM fungal ecology: The database supports investigation of how environmental factors shape AM fungal diversity and the ecology of AM fungal taxa.
• Ecosystem function research: The resource supports understanding of AM fungal roles in plant nutrient uptake and stress mitigation in ecosystems.

Methodology:

The database compiles AM fungal occurrence data from high-throughput sequencing metabarcoding studies, aggregating DNA sequence observations with geographical and environmental metadata.
