Abstract

This study examines the transcriptional consequences during the disruption of the nuclear RNAi silencing mechanism in C. elegans . Through microscopy and bioinformatic work, we demonstrate that although nuclear RNAi mutants exhibit significantly decondensed X chromosomes, chromosome-wide transcriptional de-repression is not detectable. Downstream analyses further explore the global influence of the nuclear RNAi pathway, indicating that the nuclear Argonautes HRDE-1 and NRDE-3 function through two distinct mechanisms.
