Bacterial-Fungal Interactions SFA

Integrating fungal computational sequence data analysis capabilities

The Bacterial-Fungal Interactions Science Focus Area (SFA) driven by Patrick Chain at Los Alamos National Laboratory (LANL) aims to address some of the knowledge gaps around bacterial-fungal interactions within the soil. The researchers are using a multi-omics approach to gain a predictive understanding of the bacterial-fungal interactions. This work will shed light on how microbial interactions in soil affect ecosystem services such as plant productivity, nutrient cycling, and carbon flux.

Data analysis modules:

• Bulk retrieval of fungal sequencing data, from raw data to draft contigs to finished genome
• Determination of unique genomic signatures at each taxonomic rank for fungal genomes
• Specific detection of microbial species based on unique fungal signatures

Tools:

• GOTTCHA2 (Genomic Origin Through Taxonomic Challenge): This App uses a novel taxonomic profiling method for metagenomes that is both gene-independent and signature-based. It significantly reduces false discovery rates (FDR). (Released) 
• Centrifuge Taxonomic Classifier: This App enables rapid, accurate, and sensitive labeling of metagenomic reads and quantification of species. (Beta-only)
• Kraken2 Taxonomic Classifier: This App examines the k-mers within a query sequence and maps k-mers to the lowest common ancestor (LCA) of all genomes in the reference database known to contain a given k-mer. (in Beta-only)
