What does this research mean for the field?

Ecosystems with lower levels of human intervention harbor a greater diversity of plants and plant-associated RNA viruses, including a significantly higher proportion of unclassified viruses, compared to more heavily intervened areas. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Characterize and compare plant-associated RNA virus communities between natural ecosystems with low human disturbance and areas altered by human intervention.

Overview

Geometagenomic analysis reveals higher plant RNA virus diversity in undisturbed ecosystems compared to human-altered landscapes, highlighting natural habitats as vast reservoirs of unclassified...

Key Points

Characterize and compare plant-associated RNA virus communities between natural ecosystems with low human disturbance and areas altered by human intervention.
Sampled wild and cultivated plants across two ecosystems with varying degrees of human interference and their interface zones in Minas Gerais, Brazil.
Extracted double-stranded RNA (dsRNA) and performed sequencing on an Oxford Nanopore MinION platform.
Identified and classified viral reads using bioinformatics pipelines, including BLAST, PalmScan, profile HMMs, and geNomad.
Ecosystems subjected to lower levels of human intervention exhibited higher overall plant and viral diversity.
Samples from the less-disturbed ecosystem contained a substantially higher proportion of novel, unclassified RNA viruses compared to heavily altered environments.
