Kind: research · Impact: low

## In brief

- Study in Nature Communications identifies a pathway controlling nuclear import of AGO1 in Arabidopsis.
- Authors report that a single nuclear localization signal (NLS) directs AGO1 import.
- AGO1 subcellular localization is reported to shape small RNA loading and silencing outputs.

## Why it matters

It clarifies how the subcellular location of the small RNA effector AGO1 influences which small RNAs it loads and how silencing proceeds in plants, a basic mechanism relevant to gene regulation research.
