    ..Interestingly, these AGO proteins lack key residues required for mRNA cleavage. Our findings support a two-step model for RNAi, in which functionally and structurally distinct AGOs act sequentially to direct gene silencing. ..

    ..Together, these data suggest that a conserved PUF-Ago-eEF1A complex attenuates translation elongation. ..

    ..An Argonaute protein, CSR-1, is responsible for the Slicer activity induced by secondary-type siRNAs. Secondary rather than primary siRNAs may play a major role in the destabilization of target transcripts during RNAi in C. elegans. ..

    ..Instead, our findings support a model in which CSR-1 complexes target protein-coding domains to promote their proper organization within the holocentric chromosomes of C. elegans. ..

    ..Moreover, we demonstrate that increasing the dosage of histone genes rescues the lethality associated with depletion of CSR-1 and EGO-1. These results support a positive and direct effect of RNAi on histone gene expression. ..

    ..Together, these findings suggest that C. elegans sperm transmit not only the genome but also epigenetic binary signals in the form of Argonaute/small RNA complexes that constitute a memory of gene expression in preceding generations. ..

    ..The conserved nature of CDE-1 suggests that similar sorting mechanisms may operate in other animals, including mammals. ..

    ..Together with molecular data also presented in this study, these results suggest that in C. elegans repetitive sequences trigger transcriptional gene silencing using RNAi and chromatin factors. ..

    ..On the basis of these findings, we propose that the CSR-1 pathway helps maintain the directionality of active transcription, thereby propagating the distinction between transcriptionally active and silent genomic regions...
