Deep sequencing of the degradome cDNA library in soybean

ABSTRACT: We deep sequenced a degradome library constructed from different soybean tissues. As a result, 19,830,257 represented 5,337,590 distinct signatures were obtained. 70.98% of the signatures were assigned to one soybean cDNA sequence and 24.05% matched with two cDNA sequences. 428 potential targets of small RNAs and 25 novel miRNA families were identified in soybean. A total of 211 potential miRNA targets including 150 conserved miRNA targets and 69 soybean-specific miRNA targets were identified. The signatures distribution on soybean primary miRNAs (pri-miRNAs) showed that most of the pri-miRNAs had the characteristic pattern of Dicer processing. The TAS3 small RNAs (siRNAs) biogenesis was conserved in soybean and nine Auxin Response Factors (ARFs) were identified as the TAS3 siRNA targets. The global identification of miRNAs targets would contribute to the functional research of the miRNA in soybean. one sample, We deep sequenced a degradome library constructed from different soybean tissues.

Identification of miRNAs and their target genes in developing seeds of soybean by deep sequencing

Project description:In our study, small RNA library and degradome library were constructed from developing soybean seeds for deep sequencing. We identified 26 new miRNAs in soybean by bioinformatic analysis, and further confirmed their expression by stem-loop RT-PCR. The miRNA star sequences of 38 known miRNAs and 8 new miRNAs were also discovered, providing additional evidence for the existence of miRNAs. Through degradome sequencing, 145 and 25 genes were identified as targets of annotated miRNAs and new miRNAs, respectively. Many identified miRNA targets may perform functions in soybean seed development by GO analysis. Additionally, soybean homolog of Arabidopsis SUPPRESSOR OF GENE SLIENCING 3(AtSGS3) was detected as target of the new identified miRNA Soy_25, suggesting presence of feedback control of miRNA biogenesis sample 1: Examination of small RNA in soybean seed sample 2: identification of miRNA targets in soybean seed

Identification of soybean seed developmental stage specific and tissue specific miRNA targets by degradome sequencing .

Project description:Five degradome libraries were constructed from three different seed developmental stages. Separate degradome libraries were constructed for seed coat and cotyledons to identify the tissue specific miRNAs and their potential targets. Sequencing and analysis of degradome libraries gives identification of 183 different targets for 80 known soybean miRNAs. We found 30 cotyledon specific, 18 seed coat specific and 32 miRNAs found in both tissues irrespective of the developmental stages. One interesting observation is that we found more miRNA targets in late seed developmental stages than earlier stages. Additionally, we have validated four different auxin response factor genes as targets for gma-miR160 via RNA ligase mediated 5? rapid amplification of cDNA ends (RLM-5?RACE). GO analysis indicated the enrichment of miRNA target genes in seed development. Construction of degradome libraries using cotyledons and seed coats from 3 different developmental stages

degradome sequence data

Project description:To identity the targets of miRNAs, we bundled 12 samples from different developing satages into four mixture samples. These samples were used to cosntruct degradome libraries and preform degradome sequencing on Illumina Hi-seq 2000 analyzer. More than 44.98 millions clean reads were obtained and 33.52 million reads were mapped to the soybean cDNA. The mapped reads were used to identity miRNA targets by CleaveLand4 pipeline. 4 degradome mixed samples, no replicates, but every degradome data consists of two parts data. Please note that every degradome sample has two processed and two raw data files. To have enough data, additional sequencing was performed from each sample library. And each sample raw data was processed separately (tissue_name*degradome.txt) and also combined (all_degradome*.txt).

Identification of wild soybean miRNAs and their target genes responsive to aluminum stress

Project description:In this study, two small RNA libraries and two degradome libraries were constructed from roots of Al-treated and Al-free Glycine soja seedlings. For miRNA, a total of 7,287,655 and 7,035,914 clean reads in Al-treated and Al-free small RNAs libraries were generated, and 105 known miRNAs ,51 p3/p5 strands of known miRNA and 80 novel miRNAs were identified. Among them, expression of 34 miRNAs was responsive to Al stress. Through degradome sequencing, 82 and 11 genes were identified as tagerts of known and novel miRNAs obtained from this study, respectively. Gene Ontology (GO) annotations of target transcripts indicated that 52 out of 66 targets cleaved by conserved miRNA families may play role in regulation of transcription. sample 1: Examination of small RNA in Al-free wild soybean roots; sampple 2: Examination of small RNA in Al-treated wild soybena roots; sample 3: identification of miRNA targets in Al-free wild soybean roots; sample 4: identification of miRNA targerts in Al-treated wild soybean roots

A quantitative map of human primary microRNA processing sites

Project description:Maturation of canonical microRNA (miRNA) is initiated by DROSHA that cleaves the primary transcript (pri-miRNA). Over 1,800 miRNA loci are annotated in humans, but it remains largely unknown if and at which sites the pri-miRNAs are cleaved by DROSHA. Here we performed in vitro processing on a full set of human pri-miRNAs (miRBase v21) followed by sequencing. This comprehensive profiling enabled us to classify miRNAs based on DROSHA-dependence and map their cleavage sites with respective processing efficiency measures. Only 758 pri-miRNAs are confidently processed by DROSHA, while the majority may be non-canonical or false entries. Analyses of the DROSHA-dependent pri-miRNAs show key cis-elements for processing. We observe widespread alternative processing as well as unproductive cleavage events such as “nick” or “inverse” processing. SRSF3 is a broad-acting auxiliary factor modulating alternative processing and suppressing unproductive processing. The profiling data and methods developed in this study will allow systematic analyses of miRNA regulation.

Genome-wide profiling of miRNAs and their target genes during somatic embryogenesis in cotton by small RNA and degradome sequencing

Project description:MicroRNAs (miRNAs) are endogenous non-coding ~21 nucleotide (nt) RNAs that regulate gene expression at transcriptional and post-transcriptional levels in plants and animals. They play an important role in development, abiotic stress responses or pathogen responses. miRNAs with their related target genes have been widely studied in model plants?and increasing studies have been performed on some crops?however, the number of identified miRNAs in cotton was limited, and global identification of related targets through degradome sequencing has not been developed previously. In this study, we globally identified small RNAs and their related target genes during cotton somatic embryogenesis by the high throughput small RNA and degradome sequencing technology using fresh hypocotyls and EC (embryogenic calli) of Gossypium hirsutum YZ1. A total of 36 differentially expressed conserved miRNA families of which 19 miRNA families represented by 29 precursors and 25 novel miRNAs were identified, with star sequences of 20 known miRNAs and 2 novel miRNAs discovered. 234 genes in EC and 322 genes in CK were identified as targets of 23 and 30 known miRNA families, and 16 genes were found as targets of 8 novel miRNAs. The expression profiles of several miRNAs and their targets were verified by qRT-PCR and 5’RACE were further used to validate the sliced sites of the targets. Interestingly, four TAS3 D6 and D7 were also found in both degradome libaries which can perfectly match their precursors. The profiling of the miRNAs and their target genes provides more information about the regulatory network of miRNAs during somatic embryogenesis in cotton. small RNA and degradome sequencing of CK(fresh hypocotyls) and EC (embryogenic calli) of Gossypium hirsutum YZ1
