However, the mechanism by which parental-acquired trait-specific information from RNAi is inherited by the progenies is not fully understood. Here, we identified a cytoplasmic Argonaute protein, WAGO-4, necessary for the inheritance of RNAi. WAGO-4 exhibits asymmetrical translocation to the germline during early embryogenesis, accumulates at the perinuclear foci in the germline, and is required for the inheritance of exogenous RNAi targeting both germline- and soma-expressed genes. WAGO-4 binds to 22G-RNA and its mRNA targets. Interestingly, WAGO-4-associated endogenous 22G-RNA targets the same cohort of germline genes as CSR-1 and similarly contains untemplated addition of uracil at the 3' ends. The poly(U) polymerase CDE-1 is required for the untemplated polyuridylation of WAGO-4-associated 22G-RNAs and inheritance of RNAi. Therefore, we conclude that the cytoplasmic Argonaute protein WAGO-4 also promotes the inheritance of RNAi in addition to the nuclear RNAi pathway. Overall design: In this study, we compared WAGO-4 associated small RNAs from (1) wild type animals (2) after lin-15b RNAi. And we also investigated the function of WAGO-4 in RNAi inheritance by comparing WAGO-4 associated small RNAs in (3) no RNAi treatment (4) oma-1 dsRNA treated P0 (5) F1 animals from oma-1 dsRNA-treated P0 (6) F3 animals from oma-1 dsRNA-treated P0."],"repository":["ENA"],"description_synonyms":["Post-Transcriptional Gene Silencings, post-transcriptional gene silencing by RNA, RNA, Inheritance, protein complex, Posttranscriptional, Posttranscriptional Gene Silencing, Proteins, posttranscriptional gene silencing by siRNA, Gene, protein, protein-containing complex, cosuppression, quelling, Co Suppression, Cosuppression, Protein Gene Products, Gene Proteins, RNAi, Gene Silencings, Post-Transcriptional, Post Transcriptional Gene Silencing., Gene Silencing, Interference, native protein, Protein, Gene Products, Post Transcriptional, protein aggregate, Co-Suppression, Post-Transcriptional Gene Silencing, RNA Silencing, Silencing, Post-Transcriptional Gene"],"name_synonyms":["Post-Transcriptional Gene Silencings, post-transcriptional gene silencing by RNA, RNA, Inheritance, protein complex, Posttranscriptional, Posttranscriptional Gene Silencing, Proteins, posttranscriptional gene silencing by siRNA, Gene, protein, protein-containing complex, cosuppression, quelling, Co Suppression, Cosuppression, Protein Gene Products, Gene Proteins, RNAi, Gene Silencings, Post-Transcriptional, Post Transcriptional Gene Silencing., Gene Silencing, Interference, native protein, Protein, Gene Products, Post Transcriptional, protein aggregate, Co-Suppression, Post-Transcriptional Gene Silencing, RNA Silencing, Silencing, Post-Transcriptional Gene"],"additional_accession":[]},"is_claimable":false,"name":"A cytoplasmic Argonaute protein promotes the inheritance of RNAi","description":"A cytoplasmic Argonaute protein promotes the inheritance of RNAi","dates":{"last_updated":"2025-09-24","first_public":"2018-04-30"},"accession":"PRJNA447866","cross_references":{"GEO":["GSE112475"],"taxon":["6239"],"PubMed":["29791857"]}}
