## TL;DR

Scientists found a rice virus in Argentina that was previously only known in Asia.

## Contribution

This is the first report of rice necrosis mosaic virus outside of Asia.

## Key findings

- Rice necrosis mosaic virus was identified in Argentina using metagenomics.
- RT-PCR and RNA sequencing confirmed the virus's presence and genome.
- This expands the known geographic range of the virus.

## Abstract

While rice necrosis mosaic virus (RNMV) has only been described in Asia, we identified this virus on a rice plant from Argentina using a viral metagenomic approach. We further confirmed this result by RT-PCR and small-RNA Illumina sequencing to obtain the near-complete genome and to confirm actual infection by RNMV.
