Arabidopsis AGO1 N-terminal Poly-Q domain promotes phase separation and association with stress granules during heat stress

This study shows that AGO1's Poly-Q domain enables phase separation and association with stress granules during heat stress in Arabidopsis, protecting AGO1 function without affecting small RNA activity.

Synergistic action of the Arabidopsis spliceosome components PRP39a and SmD1 in promoting post-transcriptional transgene silencing

This study shows PRP39a and SmD1 synergistically promote S-PTGS by limiting degradation of transgene aberrant RNAs, facilitating their export to the cytoplasm for dsRNA formation.

TYMV has dual action on the plant RNA silencing defense through its VSR P69 and the host RNASE THREE LIKE1

This paper shows that TYMV uses its VSR P69 and host RTL1 to partially inhibit RNA silencing amplification, allowing virus propagation without killing the host.

The Arabidopsis F-box protein FBW2 degrades AGO1 to avoid spurious loading of illegitimate small RNA

This study shows that FBW2 degrades AGO1 to prevent off-target RNA silencing by avoiding illegitimate small RNA loading.
