Small RNA-guided gene silencing at the transcriptional and post-transcriptional levels has emerged as an important mode of regulation in plants animals. Thus far, conventional sequencing small RNA libraries from rice led to identification most conserved miRNAs. Deep is effective approach uncover rare lineage- and/or species-specific microRNAs (miRNAs) any organism. In order identify new miRNAs possibly abiotic-stress regulated RNAs rice, three were constructed control seedlings exposed...

MicroRNA (miRNA)-guided target RNA expression is vital for a wide variety of biological processes in eukaryotes. Currently, miRBase (version 13) lists 142 and 353 miRNAs from Arabidopsis rice (Oryza sativa), respectively. The integration diverse networks relies upon the confirmation their targets. In contrast with well-characterized miRNA targets that are cleaved Arabidopsis, only few such have been confirmed rice. To identify small rice, we applied ‘degradome sequencing’ approach, which...

MicroRNAs are short, noncoding RNAs that play important roles in post-transcriptional gene regulation. Although many functions of microRNAs plants and animals have been revealed recent years, the transcriptional mechanism microRNA genes is not well-understood. To elucidate regulation genes, we study characterize, a genome scale, promoters intergenic Caenorhabditis elegans, Homo sapiens, Arabidopsis thaliana, Oryza sativa. We show most known these four species same type as protein-coding...

Identification of modular or community structures a network is key to understanding the semantics and functions network. While many detection methods have been developed, which primarily explore topologies, they provide little semantic information communities discovered. Although are closely related, effort has made discover analyze these two essential properties together. By integrating topology on nodes, e.g., node attributes, we study problems inference their simultaneously. We propose...

Co-expression network-based approaches have become popular in analyzing microarray data, such as for detecting functional gene modules. However, co-expression networks are often constructed by ad hoc methods, and analyses not been shown to outperform the conventional cluster analyses, partially due lack of an unbiased evaluation metric.Here, we develop a general approach both genes samples data. Our consists simple but robust rank-based network construction method, parameter-free module...

Pseudoknots have generally been excluded from the prediction of RNA secondary structures due to its difficulty in modeling. Although, several dynamic programming algorithms exist for pseudoknots using thermodynamic approaches, they are neither reliable nor efficient. On other hand, comparative methods more reliable, but often done an ad hoc manner and require expert intervention. Maximum weighted matching, algorithm pseudoknot with analysis, suffers low-prediction accuracy many cases.Here we...

Motivation: A fundamental problem of computational genomics is identifying the genes that respond to certain endogenous cues and environmental stimuli. This can be referred as targeted gene finding. Since regulation mainly determined by binding transcription factors cis-regulatory DNA sequences, most existing annotation methods, which exploit conservation open reading frames, are not effective in finding targetgenes. Results: viable approach elements known responsible for target genes. Given...

Arabidopsis microRNA (miRNA) genes (MIR) give rise to 20- 22-nt miRNAs that are generated predominantly by the type III endoribonuclease Dicer-like 1 (DCL1) but do not require any RNA-dependent RNA Polymerases (RDRs) or Polymerase IV (Pol IV). Here, we identify a novel class of non-conserved MIR two small species, species and 23- 27-nt at same site. Genetic analysis using pathway mutants reveals RNAs typical DCL1 associated with Argonaute (AGO1). In contrast, accumulation from...

Abstract Background Many eukaryotic genomes encode cis -natural antisense transcripts ( -NATs). Sense and may form double-stranded RNAs that are processed by the RNA interference machinery into small interfering (siRNAs). A few so-called nat-siRNAs have been reported in plants, mammals, Drosophila , yeasts. However, many questions remain regarding features biogenesis of nat-siRNAs. Results Through deep sequencing, we identified more than 17,000 unique siRNAs corresponding to -NATs from...

MicroRNAs (miRNAs), which originate from precursor transcripts with stem-loop structures, are essential gene expression regulators in eukaryotes. We report 19 miRNA precursors Arabidopsis that can yield multiple distinct miRNA-like RNAs addition to miRNAs and miRNA*s. These precursor-derived often arranged phase form duplexes an approximately two-nucleotide 3'-end overhang. Their production depends on the same biogenesis pathway as their sibling does not require RNA-dependent RNA polymerases...
