NASA OSDR Plant Microbiome — Integrated Interactive Report

Overview

This report integrates every plant-associated microbiome study currently curated from the NASA Open Science Data Repository (OSDR) into a single relational database and a set of linked, interactive dashboards. Study, assay, factor and sample metadata are sourced from OSDR; diversity metrics are computed by the pipeline.

Study Registry

Curated, versioned registry of OSDR plant-microbiome accessions. Each links to its OSDR landing page.

Study-Metadata Graph Database

Heterogeneous knowledge graph linking studies to their shared metadata entities (hardware, organism, assay, region, tissue, factor). Studies that cluster together share comparison-relevant attributes; the same graph is exported as GraphML / Cypher for Gephi, Cytoscape or Neo4j.

Guild Inference (ML): Beneficial · Plant Pathogen · Human Pathogen

Multiclass semi-supervised inference of microbial ecological guilds, fusing a curated prior knowledge base, guild-specific trait features, co-occurrence guilt-by-association and label spreading. Crucially, the two very different meanings of pathogen are kept on separate axes: a plant-pathogen (phytopathogen, e.g. Ralstonia) is a crop-yield risk, whereas a human/clinical pathogen (e.g. Staphylococcus) is a food-safety / crew-health risk. They co-occur in the same hardware but threaten different hosts and demand different responses. See data/processed/GUILD_METHOD.md.
