Genome-wide identification of alternate bearing-associated miRNA in the olive tree (Olea europaea)

ABSTRACT: We aimed to identify miRNA regulated by alternate bearing in O. europaea. For this purpose, six olive (Olea europaea L. )(Ayvalık variety) small RNA libraries were constructed from fruits (ripe and unripe) and leaves ("on-year" and "off-year" mature -leaven in November and juvenile - leaven in July plants) and sequenced by high-throughput Illumina sequencing. Bioinformatics analyses of 93,526,915 reads identified 135 conserved miRNA, belonging to 22 miRNA families in olive tree. In addition, 38 novel miRNA were discovered in the datasets. Expression of olive tree miRNA varied greatly among the six libraries, indicating contribution of diverse miRNA in balancing between reproductive and vegetative phases. The differential expression of miRNA was evaluated on the basis of the developmental phase of the samples. Sequences of six olive miRNAs (Olea europaea L. )(Ayvalık variety) plants (ripe and unripe fruits, leaves of mature and juvenile plants of both "on-year" and "off-year") were generated by Illumina sequencing

Nutrition metabolism plays an important role in the alternate bearing of the olive tree (Olea europaea L.)

Project description:We carried out genome wide transcriptome analyses in different organs and developmental stages of the olive tree using the NimbleGen Array oligonucleotide probe sets. Cluster analyses of the genes showed that samples collected from different organs could be sorted into separate groups. The nutritional control had a particularly remarkable impact on the alternate bearing for O. europaea, as shown by the differential expressions of transcripts under different developmental phases and organs Six sample sets were prepared for array analyses: i) unripe fruit (UF); ii) ripe fruit (RF); iii) “on-year” mature leaf (November sample, ON-M); iv) “on-year” juvenile leaf (July sample, ON-J); v) “off-year” mature leaf (November samples, OFF-M); and vi) “off-year” juvenile leaf (July sample, OFF-J).

MicroRNA sequence and expression analysis of rat liver tissue exposed to aflatoxin B1 by deep sequencing

Project description:We report the application of illumina deep sequencing technology for high-throughput profiling of microRNA in aflatoxin B1 treated rat liver tissue, as well as normal liver tissue. miRNAs of miR-17-92 cluster, thought to be tumor activating miRNAs, were down-regulated. miR-34a, considered to be a tumor suppressor, was up-regulated.Novel miRNAs and miRNA base alteration caused by SNP or editing were predicted and summarized. Examination of 2 microRNA profiles in 2 liver tissues under different treatments.

Characterization and function of Tomato yellow leaf curl virus-derived small RNAs generated in the tolerant and susceptible tomato varieties using deep sequencing

Project description:High-throughput sequence analysis of small RNAs of TYLCV-tolerant (containing tolerance gene Ty-1) and susceptible varieties indicated that miRNA-like vsRNAs and secondary vsiRNAs are mainly contributed to hotpots. Interestingly, various characteristics of vsRNAs among each sample are consistent, but in different number of expression; Deep sequencing of degradome provided evidence for the function of vsRNAs-mediated viral transcripts slicing; And bisulfite sequencing PCR suggested the geminivirus DNA methylation induced by vsRNAs. Comparison of the expression quantity and trend of viral DNA, mRNA and vsRNA inferred that the quantity of vsRNAs is significantly corresponding to the expression level of viral mRNA. Nevertheless, vsRNAs had finite effect on inhibition of virus replication and expression. Here, we also speculated that by RDR catalysis of vsRNAs amplification, the tolerance gene Ty-1 may take an effective inhibition of viral transcription at the beginning of TYLCV infection. Examination of 6 different sRNA and 4 degradome library in 2 tomato material. The main result of our paper is distinguish the host plant sRNA and viral-derived sRNA from the .fa files (MMS_21dpi, 30dpi and TY1S_21dpi, 30dpi).

MiRNA signatures in cell cycle sorted cells [HeLa_H295R_miRNA_seq]

Project description:For the further examination of cell cycle dependent miRNA expression profile, DNA content based fluorescence activated cell sorting (cell cycle sort) was performed on human transformed cancer cell lines. Phase-dependent miRNA expression profiling was performed on G1, S and G2 phases. Results were validated by quantitative real-time PCR. Phase-dependent miRNA expression profiling was performed on sorted human cancer (cervical - HeLa, adrenocortical - NCI-H295R) cells). G1, S and G2 phases were successfully sorted and analyzed.

Deep Sequencing identifies regulated small RNAs in Dugesia japonica

Project description:We applied Illumina sequencing to identify microRNAs (miRNAs) and piwi-interacting small RNAs (piRNAs) in Dugesia japonica. Dugesia were cut up after seven day’s starvation. DJ1 is the whole Dugesia body, DJ2 is the head part, DJ3 is the tail part, DJ4 is the left part and DJ5 is the right part. Total RNA was extracted by Trizol, and preserved in ethanol, stored at -80°C until further use. 5 samples examined?DJ1,DJ2,DJ3,DJ4,DJ5. SRA study (not submitted by GEO): SRP017693

Deep sequencing identifies PD0325901 modulated microRNAs in the J1 mESCs

Project description:PD0325901 is involved in improving reprogramming efficiency during inducing pluripotent stem cells (iPSC) or maintain a blastocyst-like state in embryonic stem cells (ESC). However, the knowledge about this small molecule regulating miRNAs in ESC was limited. To understand the role of miRNAs during PD03-induced ESC maintenance and gain an insight how PD0325901 regulates miRNAs expression; we performed small RNA sequencing using Illumina HiSeq 2000 under the compounds treatment. The data show the miRNAs regulated by PD0325901. J1 mESCs maintained in medium containing 1000 U/mL LIF and supplemented with PD0325901 for 24 hours, J1 treated with DMSO was set as control. Then total RNA was extracted for analysis.
