Project description:To identify more targets in soybean, particularly specific targets of Cd-stress-responsive miRNAs, high-throughput degradome sequencing was used. In total, we obtained 8913111 raw reads from the library which was constructed from a mixture of four samples (HX3-CK, HX3-Cd-treatment, ZH24-CK and ZH24-Cd-treatment). After removing the reads without the CAGAG adaptor, 5430126 unique raw-reads were obtained. The unique sequences were aligned to the G. max genome database, and 6516276 reads were mapped to the genome. The mapped reads from the libraries represented 51481 annotated G. max genes.

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).

Project description:To gain insight into the functions of salt-regulated miRNAs, target genes were identified through degradome sequencing approach. Three cotton RNA libraries were constructed and sequenced under normal consideration, osmotic and ionic stress. A total of 73,988,644 reads represented by 3,254,054 unique reads from the 5â ends of uncapped and poly-adenylated RNAs were obtained. The PairFinder software was used to identify the sliced targets for the known miRNAs and novel miRNAs. These sequences were further compared with transcriptome sequencing data of G. arboretum and G. raimondii. We obtained the data from (Cotton Genome Project, http://cgp.genomics.org.cn/page/species/index.jsp).Based on degradome sequencing, 31 target genes were identified for 20 cotton miRNA families. The abundance of transcripts was plotted for each transcript. Conserved miRNAs target conserved homologous genes in diverse plant species. Three cDNA libraries were constructed using total RNA obtained from control samples (CK), the 4 h and 5 d salt-treated samples. A total of 74,351,180 sequence reads were obtained from three libraries. After removing the 3p and 5p adapter sequences and filtering out low quality âânââ sequences, 864,720, 1,217,757 and 1,171,577 clean reads remained in the CK, 4 h and 5 d samples, respectively.

Project description:In this study, in order to identify miRNA targets, a degradome library derived from anthers of the WT and GMS (Genetic Male Sterility) mutant representing three stages of development was constructed and sequenced, resulting in the generation of 24.6 million raw reads. After removal of low quality sequences and adapter sequences, 24.4 million clean reads were obtained and 98% were 20 or 21 nt in length as expected in that normally length distribution peak of degradome fragment is between 20 and 21 nt [Addo-Quaye C, Eshoo TW, Bartel DP, Axtell MJ: Endogenous siRNA and miRNA targets identified by sequencing of the Arabidopsis degradome.

Project description:Drought is a major limiting factor in foraging grass yield and quality. Medicago ruthenica is a high-quality forage legume with drought resistance, cold tolerance, and strong adaptability. In this study, we integrated transcriptome, small RNA, and degradome sequencing in identifying drought response genes, miRNAs, and key miRNA-target pairs in M. ruthenica under drought and re-watering treatment conditions. A total of 3,905 genes and 50 miRNAs (45 conserved and 5 novel miRNAs) were significantly differentially expressed between the re-watering (RW) vs. drought (DS) comparison and control (CK) groups. The degradome sequencing analysis revealed that 348 miRNAs (37 novel and 311 conserved miRNAs) were identified with 6,912 target transcripts, forming 11,390 miRNA-target pairs in the three libraries. There were 38 differentially expressed targets from 16 miRNAs in DS vs. CK, 31 from 11 miRNAs in DS vs. RW, and 6 from 3 miRNAs in RW vs. CK; 21,18, and 3 miRNA-target gene pairs showed reverse expression patterns in DS vs. CK, DS vs. RW, and RW vs. CK comparison groups, respectively. These findings provide valuable information for further functional characterization of genes and miRNAs in response to abiotic stress, in general, and drought stress in M. ruthenica, and potentially contribute to drought resistance breeding of forage in the future.

Project description:Cadmium (Cd) influence in rice is a growing global environmental concern. Although many miRNAs and target genes have been identified in rice exposure to Cd stress, no comprehensive study has been done comprising integrative analysis of small RNAs, degradome and trascriptome sequencing to identify Cd-regulated miRNAs and their targets under Cd stress. In this study, 40 miRNAs including 38 known miRNAs representing 22 miRNA families and 2 novel miRNAs were substantially altered in response to Cd exposure. 18 differentially altered target genes were inversely correlated with 18 Cd responsive miRNAs. Majority of these targeted genes are transcript factors such as Auxin response factor 13 (ARF13), Scarecrow-like protein 6 (SCL6), Squamosa promoter-binding-like proteins (SPLs), Nuclear transcription factor Y subunit A-6 (NFYA6), Gibberellin-dependent avian myeloblastosis virus oncogene (GAMYB) and No apical meristem protein domain containing proteins (NACs), most of which were involved in signal transduction such as abscisic acid (ABA), Auxin, Gibberellin acid (GA) and MAPK (Mitogen-activated protein kinase). Functional analysis revealed that genes involved in photosynthesis pathway (osa00196, osa00195 and osa00710) and protein degradation pathway (osa04612) were identified to be participated in response to Cd in rice, including osa-miR156I-5p_R-1/SPLs, osa-miR171a_1ss12CT/DEGP10 and osa-miR169r-5p_R/NFYA6 circuits, respectively. We conclude that a combination of transcriptome, sRNAs and the degradome would confer a useful approach to investigate miRNA-mediated molecular mechanisms underlying plant response to Cd stress.

Project description:MicroRNA (miRNA)-guided target RNA expression is vital for a wide variety of biological processes in eukaryotes. The integration of miRNAs in diverse biological networks relies upon the confirmation of their RNA targets. Most miRNA targets in Arabidopsis are validated, but those in rice are yet to be characterized. To identify transcriptome-wide small RNA targets in rice, we generated 20-nt small cDNA library and obtained nearly 40 million reads. Sequence analysis yielded 11,552,007 unique reads that can be perfectly mapped to the rice genome. Sequence analysis not only found homologous targets for conserved miRNAs but also many novel targets. Besides miRNA atregts, the rice degradome contained fragments derived from MIRNA precursors. A closer inspection of these fragments revealed a unique pattern distinct from siRNA producing loci. This attribute can serve as one of the ancillary criteria for separating miRNAs from siRNAs in plants.
