# Plant viruses traveling without passport

## TL;DR

A new study discovers the first plant virus that can infect plants without a movement protein, challenging previous assumptions about viral infection mechanisms.

## Contribution

The study identifies a plant virus that infects hosts without a movement protein, a first in virology.

## Key findings

- A plant virus was found to colonize its host without a movement protein.
- This discovery challenges the long-held belief that movement proteins are essential for plant virus infection.

## Abstract

All plant viruses were thought to encode in its genome a movement protein that acts as a “passport,” allowing active movement within the host. A new study in PLOS Biology characterizes the first plant virus that can colonize its host without encoding this protein.

All plant viruses were thought to encode in its genome a movement protein that acts as a “passport”, allowing active movement within the host. This primer highlights a study that characterizes the first plant virus that can colonize its host without encoding this protein.
