Arabidopsis ARGONAUTE 1 Binds Chromatin to Promote Gene Transcription in Response to Hormones and Stresses

Conventional RNA interference (RNAi) pathways suppress eukaryotic gene expression at the transcriptional or post-transcriptional level. At the core of RNAi are small RNAs (sRNAs) and effector Argonaute (AGO) proteins. Arabidopsis AGO1 is known to bind microRNAs (miRNAs) and post-transcriptionally repress target genes in the cytoplasm. Here, we report that AGO1 also binds to the chromatin of active genes and promotes their transcription. We show...
