A single NLS directs AGO1 import shaping small RNA loading and silencing outputs in Arabidopsis
Nature · By Belén Moro ·
The 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.
