(Submitter supplied) A series of transfections was performed in Drosophila S2 cells to explore: 1) the types of target sites that Drosophila microRNAs recognize, 2) the relative functional efficacy of these sites in mediating repression, and 3) the determinants that allow some sites to have greater potency than others. 3p-seq was also performed to help reannotate and quantify the landscape of 3' UTRs in Drosophila S2 cells.

(Submitter supplied) modENCODE_submission_2744 This submission comes from a modENCODE project of Eric Lai. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We plan to generate a comprehensive catalog of expressed and functional microRNAs, and generate biological evidence for their regulatory activity. We plan also to delineate the primary transcription units of microRNA genes. Finally, we plan to annotate other classes of non-miRNA expressed small RNAs, as least some of which may define novel classes of small RNA genes. more...

(Submitter supplied) Small RNAs (21-24 nt) are involved in gene regulation through translation inhibition, mRNA cleavage, or directing chromatin modifications. In rice, currently ~240 miRNAs have been annotated. We sequenced more than four million small RNAs from rice and identified another 24 miRNA genes. Among these, we found a novel class of miRNAs that derive from natural cis-antisense transcript pairs. This configuration generates miRNAs that can perfectly match their targets. more...

(Submitter supplied) microRNAs play crucial roles in the early development of an organism. However the regulation of transcription through the action of microRNAs during the initial embyonic development has not been studied. We used microarrays to detail the effect of maternal microRNA mir-34 in regulation of zygotic trancription during the initial stages of Zebrafish embryonic development from one cell stage through the maternal-zygotic transition up to 24 hours post fertilization.

(Submitter supplied) MicroRNAs (miRNAs) are endogenous RNA molecules that contribute to the regulation of gene expression post-transcriptionally. Recently, patterns of sequence evolution and evolutionary emergence of miRNAs have been analyzed in detail. However, the extent to which miRNA expression levels vary within and between species, the role of stabilizing selection versus other evolutionary mechanisms in shaping the temporal dynamics of these changes, and how this variation might unveil the interplay between miRNAs and mRNAs remain poorly understood. more...

(Submitter supplied) Endogenous small RNAs, including microRNAs (miRNAs) and short-interfering RNAs (siRNAs), function as posttranscriptional or transcriptional regulators in plants. miRNA function is essential for normal development and therefore likely to be important in the growth of the rice grain. To investigate the likely roles of miRNAs in rice grain development we carried out deep sequencing of the small RNA populations of rice grains. more...

(Submitter supplied) To identify endogenous siRNAs in response to bacterial pathogen at a whole genome level, we performed small RNA profiling on Pseudomonas syringae-challenged Arabidopsis and obtained more than 24.6 million (M) reads with more than 3.8 M unique small RNAs that perfectly matched Arabidopsis genome. We found some new miRNAs and some miRNA induced by pathogen infection. We also identified more than 20K unique siRNAs from the NAT mRNAs and 22K siRNAs from the introns or intron-exon junction of the NATs.

(Submitter supplied) MicroRNAs (miRNA) are small, endogenous RNAs that regulate the expression of mRNAs posttranscriptionally. To identify miRNAs that produce twin products, we sequenced these five small RNA libraries and collected other published datasets to represent a systematic coverage of the major tissue types (head, body and sexual organs) in D. melanogaster. To survey the repression effects of twin miRs on the their targets, we dissected testes from adult flies that lacked Dm310s due to a knock-out mutation (Tang, et al. more...

(Submitter supplied) MicroRNAs (miRNAs) are small, endogenously expressed RNAs that regulate mRNAs post-transcriptionally. The class of miRNA genes, like other gene classes, should experience birth, death and persistence of its members. We carried out deep sequencing of miRNAs from three species of Drosophila, and obtained 107,000 sequences that map to no fewer than 300 loci that were not previously known. We observe a large class of miRNA genes that are evolutionarily young, with a rate of birth of 12 new genes per million years (Myr). more...

(Submitter supplied) We report the comprehensive sequencing of small RNA libraries created from different developmental stages of the basal chordate, Ciona intestinalis. Surprisingly, half of the identified miRNA loci encode not two, but up to four distinct small RNAs. These additional RNAs, termed “moRs”, are generated from sequences adjacent to the predicted ~60-nt pre-miRNA. moRs appear to be produced by RNAse-III-like processing, are ~20-nt in length, have 5’-monophosphate and 3’-hydroxl termini, and like miRNAs, are developmentally regulated.
