Provenance — who produced it, who reused it
Linked to 1 papers in the literature. Roles are inferred factual signals (who deposited the data vs who reused it), with counts — never a judgement about any author.
1 further paper cites this accession but reuse could not be confirmed.

Amplicon sequencing of plant metagenome using 454 GS FLX+ platform, producing 4,730 medium-length reads totaling 3.9 million bases. This 454-based amplicon dataset enables taxonomic classification of plant-associated microbiota; 454 longer reads improve species-level resolution versus short-read platforms, though modest read count limits community depth.
The F grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
