Distinct thresholds condition sense PTGS initiation and amplification.

The paper identifies distinct thresholds for initiating and amplifying post-transcriptional gene silencing (S-PTGS) in plants, showing that transgene expression levels determine amplification capacity.

The tryptophan-binding pockets of Arabidopsis AGO1 facilitate amplified RNA interference via SGS3

The paper identifies that tryptophan-binding pockets in Arabidopsis AGO1 are essential for RDR6-dependent siRNA amplification through interactions with SGS3.

The Arabidopsis RNA-binding protein SGS3 is recruited to the chromatin remodeler CHR11 to promote siRNA production from protein-coding genes

The paper shows SGS3 recruits CHR11 to select nuclear RNAs for export to the cytosol, promoting siRNA production from protein-coding genes under stress.

RST1 and RIPR connect the cytosolic RNA exosome to the Ski complex in Arabidopsis

This study identifies RST1 and RIPR as proteins connecting the cytosolic RNA exosome to the Ski complex in Arabidopsis, showing their role in RNA quality control.
