Abstract |
ARGONAUTE (AGO) proteins function in small RNA (sRNA)-based RNA silencing pathways to regulate gene expression and control invading nucleic acids. In posttranscriptional RNA silencing pathways, plant AGOs associate with sRNAs to interact with highly sequence-complementary target RNAs. Once the AGO-sRNA-target RNA ternary complex is formed, target RNA is typically repressed through AGO-mediated cleavage or through other cleavage-independent mechanisms. The universe of sRNAs associating with diverse plant AGOs has been determined though AGO immunoprecipitation (IP) and high-throughput sequencing of co-immunoprecipitated sRNAs. To better understand the biological functions of AGO-sRNA complexes, it is crucial to identify the repertoire of target RNAs they regulate. Here I present a detailed AGO-RNA IP followed by high-throughput sequencing (AGO RIP-Seq) methodology for the isolation of AGO ternary complexes from plant tissues and the high-throughput sequencing of AGO-bound target RNAs. In particular, the protocol describes the IP of slicer-deficient hemagglutinin (HA)-tagged AGO proteins expressed in plant tissues, the isolation of AGO-bound RNAs, and the generation of target RNA libraries for high-throughput sequencing. |
