High throughput sequencing of mutants in the WAGO pathway

ABSTRACT: Diverse naturally-occurring small RNA species interact with Argonaute proteins to mediate sequence-specific regulation in animals. In addition to micro-RNAs (miRNAs), which collectively regulate thousands of target mRNAs, other endogenous small RNA species include the Piwi-associated piRNAs that are important for fertility and a less well-characterized class of small RNAs often referred to simply as endo-siRNAs. Here we have utilized deep-sequencing technology and C. elegans genetics to explore the biogenesis and function of endo-siRNAs. We describe conditional alleles of the dicer-related helicase, drh-3, that implicate DRH-3 in both the response to foreign dsRNA as well as the RNA-dependent RNA Polymerase (RdRP)-dependent biogenesis of a diverse class of endogenous small RNAs, termed 22G
