Environmental Sequencing?

Culturing and PCR have not yet revealed pathogens which may be responsible for the sword fern die-off.  Here are some readings and references, gathered unsystematically from the recent literature, about the use of next-generation, environmental sequencing and microarrays for identifying pathogens.

1. Metagenomics (wikipedia)
2. Putative pathogenicity genes of Phytophthora cinnamomi identified via RNA-Seq analysis of pre-infection structures
3. Moleculo long-read sequencing facilitates assembly and genomic binning from complex soil metagenomes
4. GeoChip as a metagenomics tool to analyze the microbial gene diversity along an elevation gradient
5. The PathoChip, a functional gene array for assessing pathogenic properties of diverse microbial communities
