Distinct thresholds condition sense PTGS initiation and amplification.

Martin Lacroix, Nicolas Butel, Andana Barrios…·Hervé Vaucheret

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

Taline Elmayan, Thomas Blein, Emilie Elvira‐Matelot…·Hervé Vaucheret

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

Rapid meiotic prophase chromosome movements in Arabidopsis thaliana are linked to essential reorganization at the nuclear envelope

Laurence Cromer, Mariana Tiscareño-Andrade, Sandrine Lefranc…·Mathilde Grelon

This study shows that Arabidopsis thaliana meiotic centromeres undergo rapid movements during zygotene and pachytene stages, which depend on SUN-domain proteins and are disrupted in sun1 sun2 mutants.
