Deep sequencing of small RNAs

ABSTRACT: Recently, we demonstrated that RDRs had a general function to synthesize antisense RNAs from sense transcripts of protein-coding genes. In this study, we analyzed whether RDR-mediated antisense RNAs were processed into small RNAs by deep sequencing using SOLiD. Deep sequencing identified 1,645 RDR1/2/6-mediated smRNA loci in drought stress and control conditions.

Deep sequencing of uncapped RNA in rdr1/2/6 and wild-type Arabidopsis plants

Project description:Our previous experiment on biogenesis mechanisim of stress-inducible antisense RNAs showed that accumulation of antisense RNA in a drought-inducible gene, RD29A locus was decreased in rdr1/2/6 triple mutant. The RD29A antisense RNA did not have CAP structure and poly(A) tail. We applied deep sequencing of uncapped RNA using SOLiD to identify RDR1/2/6-mediated antisense RNAs in genome-wide. We identified 1) 975 RDR1/2/6-mediated antisense RNA loci on which no. of sequence tags is decreased in rdr1/2/6 and makes peak and 2) 1,613 RDR1/2/6-mediated antisense RNA loci on which no. of the tags is decreased in rdr1/2/6 and enriched on antisense strand of exons. They were grouped into 1,959 non-redundant loci.

Comprehensive Analysis of RDR1/2/6-independent Small RNAs in Arabidopsis thaliana

Project description:Plant small RNAs (sRNAs) regulate key physiological mechanisms through post-transcriptional and transcriptional silencing of gene expression. sRNAs fall into two major categories: those that are reliant on RNA Dependent RNA Polymerases (RDRs) for biogenesis and those that aren’t. Known RDR-dependent sRNAs include phased and repeat-associated short interfering RNAs, while known RDR-independent sRNAs are primarily microRNAs (miRNAs) and other hairpin-derived sRNAs. In this study, we produced and analyzed sRNA-seq libraries produced from rdr1/rdr2/rdr6 triple mutant plants. We found 58 previously annotated MIRNA loci that were dependent on RDR function, casting doubt on their classification as MIRNAs. We also found 38 RDR-independent sRNA clusters that were not MIRNAs or otherwise hairpin-derived. These 38 sRNA loci have novel biogenesis mechanisms, and frequently arise from protein-coding genes. Altogether, our analysis suggests that these 38 sRNA loci represent one or more new types of sRNA loci in Arabidopsis thaliana.

Global analysis of RNA-dependent RNA Polymerase-dependent small RNAs reveals new substrates and functions for these proteins and SGS3 in Arabidopsis

Project description:In plants, smRNAs are often derived from long double-stranded RNA (dsRNA) molecules synthesized by one of the six genomically-encoded RNA-dependent RNA Polymerase (RDR) proteins. However, the full complement of the RDR-dependent smRNAs and functions that these proteins and their RNA-binding co-factors play in plant RNA silencing has not been fully uncovered. To address this gap, we performed a global genomic analysis of all six RDRs and two of their co-factors to find new substrates for RDRs and targets of the resulting RDR-derived siRNAs to uncover new functions for these proteins in plants. Based on these analyses, we identified substrates for the three RDR clade proteins (RDR3 - 5), which had not been well-characterized previously. We also identified new substrates for the other three RDRs (RDR1, 2, and 6) as well as the RDR2 co-factor RNA-DIRECTED DNA METHYLATION 12 (RDM12) and the RDR6 co-factor SUPRESSOR OF GENE SILENCING 3 (SGS3). These findings revealed that the target substrates of SGS3 are not limited to those solely utilized by RDR6, but that this protein seems to be a more general co-factor for the RDR family proteins. Additionally, we found that RDR6 and SGS3 are involved in the production of smRNAs that target transcripts related to abiotic stresses including water deprivation, salt stress, and ABA response, and as expected the levels of these mRNAs are increased in rdr6 and sgs3 mutant plants. Correspondingly, plants that lack these proteins (rdr6 and sgs3 mutants) are hypersensitive to ABA treatment, tolerant to high levels of PEG8000, and have higher survival rate under salt treatment in comparison to wild-type (Col-0). In total, our analyses have provided an extremely data-rich resource for uncovering new functions of RDR-dependent RNA silencing in plants, while also revealing a previously unexplored link between the RDR6/SGS3-dependent pathway and plant abiotic stress responses.

TMV-derived Small RNAs Reveals Role for Arabidopsis thaliana RNA-dependent RNA Polymerases in Viral siRNA Biogenesis

Project description:Using a crucifer-infecting strain of Tobacco Mosaic Virus (TMV-Cg) and Arabidopsis thaliana as a model system, we analyzed the viral small RNA profile in wild-type plants as well as rdr mutants by applying small RNA deep sequencing technology. Over 100,000 TMV-Cg-specific small RNA reads, mostly of 21- (78.4%) and 22-nucleotide (12.9%) in size and originating predominately (79.9%) from the genomic sense RNA strand, were captured at an early infection stage, yielding the first high-resolution small RNA map for a plant virus. The TMV-Cg genome harbored multiple, highly reproducible small RNA-generating hot spots that corresponded to regions with no apparent local hairpin-forming capacity. Significantly, both the rdr1 and rdr6 mutants exhibited globally reduced levels of viral small RNA production as well as reduced strand bias in viral small RNA population, revealing an important role for these host RDRs in viral siRNA biogenesis. In addition, an informatics analysis showed that a large set of host genes could be potentially targeted by TMV-Cg-derived siRNAs for posttranscriptional silencing, raising the interesting possibility for a hidden layer of widespread virus-host interactions that may contribute to viral pathogenicity and host specificity. Profiling of TMV-Cg derived small RNAs in systemically infected tissues of wild type (Col-0) Arabidopsis as well as the rdr1and rdr6 mutants, at 3 days post-infection.

Virus-derived siRNAs in Arabidopsis thaliana

Project description:We investigated the role of A. thaliana RDRs in the RNAi-mediated viral immunity by using a mutant of cucumber mosaic virus (CMV) that does not express the VSR protein 2b. CMV contains three positive-strand genomic RNAs and the 2b protein encoded by RNA2 is essential for infection by suppressing antiviral silencing initiated by either DCL4 or DCL2. Our results demonstrate an essential role for the amplification of viral siRNAs by either RDR1 or RDR6 in antiviral silencing. Further analyses, including Illumina sequencing of more than 3.5 million viral siRNAs, indicated target specificity of the two antiviral RDRs.

Biological function of antisense RNAs that are synthesized by RNA-dependent RNA polymerases under rehydration

Project description:To identify RDR1/2/6-dependent antisense RNA loci under 2hr drought stress and 2hr rehydration, expression profiles of Poly (A+) RNA between rdr1/2/6 and wild-type using the custom microarray (GPL19830) were analyzed. rdr1/2/6 and wild-type plants (Arabidopsis thaliana ecotype Columbia) were grown on MS medium for 2 weeks. Then, the plants were transferred to plastic dish and kept for 2hr. Poly (A+) RNA from 100Î¼g total RNA by treating with Ambion Poly A purist twice.5 ng of Poly (A+) RNA were used for the expresion profiling using the custom array (GPL19830).

A plant immune protein enables broad antitumor response by rescuing microRNA deficiency in cancers [miRNA-seq]

Project description:Cancer cells are featured with uncontrollable activation of cell cycle and proliferation,and microRNA deficiency drives tumorigenesis. The RNA-dependent RNA polymerase (RDR) is essential for small RNA-mediated immune response in plants, but absent in vertebrates with adaptive immunity. Here we show that ectopic expression of plant RDR1 can generally inhibit the proliferation of different cancer cells. Interestingly, we find that abnormal AGO2-free microRNA isoforms with 1-nucleotide shortening at the 3’ end are widely accumulated in many tumors. RDR1 with nucleotidyltransferase activity can recognize and modify these problematic microRNAs with mononucleotides to restore their AGO2 loading efficiency, which eventually rescues microRNA deficiency and elevates microRNA expression to target cell cycle in cancer specifically. The wide antitumor effects of RDR1 can be visualized in multiple xenograft tumor models in vivo, which can be realized by adeno-associated virus-mediated delivery. Altogether, we develop a broad microRNA-mediated antitumor stratagem using the plant immune protein RDR1.
