Arabidopsis lyrata flowering tissues small RNAs

ABSTRACT: Small RNA sequences from Arabidopsis lyrata flowering tissues, as isolated from flowering tissues of two biological replicates. These data were analyzed to 1) discover new micoRNAs in A. lyrata 2) examine microRNA processing accuary in A. lyrata and 3) to examine patterns of 24nt siRNA accumulation in A. lyrata. Two small RNA libraries from flowering tissues of two biological replicates were analyzed using an Applied Biosystems SOLiD™ System

Arabidopsis lyrata small RNAs: transient MIRNA and small interfering RNA loci within the Arabidopsis genus.

The Plant cell 20100420 4

Twenty-one-nucleotide microRNAs (miRNAs) and 24-nucleotide Pol IV-dependent small interfering RNAs (p4-siRNAs) are the most abundant types of small RNAs in angiosperms. Some miRNAs are well conserved among different plant lineages, whereas others are less conserved, and it is not clear whether less-conserved miRNAs have the same functionality as the well conserved ones. p4-siRNAs are broadly produced in the Arabidopsis genome, sometimes from active hot spot loci, but it is unknown whether indivi ...[more]

Repertoire and evolution of miRNA genes in four divergent nematode species

Project description:We have performed small RNA sequencing in the nematodes Caenorhabditis elegans, C. briggsae, C. remanei and Pristionchus pacificus, which have diverged up to 400 million years ago, to establish the repertoire and evolutionary dynamics of miRNAs in these species. In addition to previously known miRNA genes from C. elegans and C. briggsae we demonstrate expression of many of their homologs in C. remanei and P. pacificus, and identified in total more than 100 novel expressed miRNA genes, the majority of which belong to P. pacificus. More than half of all identified miRNA genes were found to be conserved at the seed level in all four nematode species, whereas only a few miRNAs appear to be species-specific. In our compendium of miRNAs we observed evidence for known mechanisms of miRNA evolution, including antisense transcription and arm switching, as well as miRNA family expansion through gene duplication. In addition, we identified a novel mode of miRNA evolution, termed ‘hairpin shifting’, in which an alternative hairpin is formed with up- or downstream sequences, leading to shifting of the hairpin and creation of novel miRNA* species. Finally, we identified 21U-RNAs in all four nematodes, including P. pacificus, where the upstream 21U-RNA motif is more diverged. However, the genomic distribution of 21U-RNA clusters in P. pacificus appears more scattered throughout the genome as compared to C. elegans. The identification and systematic analysis of small RNA repertoire in four nematode species described here provides a valuable resource for understanding the evolutionary dynamics of miRNA-mediated gene regulation. Small RNAs were cloned from mixed stage animals. Sequencing was performed using the 454 GS FLX platform.

Zebrafish Zili- and Ziwi-interacting small RNAs

Project description:Small RNAs exert an effect through diverse RNA interference pathways to transcriptionally or post-transcriptionally silence their targets. The Piwi-interacting RNAs (piRNAs) represent a germline-specific small RNA pathway where Piwi proteins themselves are thought to mediate piRNA biosynthesis. Here, we provide strong evidence for a piRNA amplification loop in zebrafish, in which Ziwi and Zili bind piRNAs of opposite polarity. Furthermore, we describe a function for Zili in transposon defense and germ cell differentiation, as well as a crucial function in meiosis, significantly extending the function of Piwi proteins beyond the control of transposable elements in vertebrates. small RNA from total gonads or Argonaute IPs were cloned and sequenced using 454 GS FLX system.

RNA-Seq of Arabidopsis thaliana and Arabidopsis lyrata plants primed by insect eggs from Pieris brassicae and triggered by insect herbivory

Project description:In Arabidopsis thaliana it is known that plants that harboured eggs of the White cabbage butterfly (Pieris brassicae) before larval feeding can defend better against the herbivore stress. As Arabidopsis thaliana is an annual plant we were interested in the plant defense and possible priming reaction of the closest biannual/perennial relative Arabidopsis lyrata. The main aim of the experiment was to compare the effect induced by insect egg deposition of Pieris brassicae between A. thaliana and A. lyrata plants grown in parallel on the transcriptional level. We used a full factorial setup consisting of a) untreated control plants , b) plants which experienced eggs for 6 days without larval feeding after that period, c) plants which experienced no eggs before larval feeding for 24 hours d) plants which experienced eggs for 6 days and larval herbivory for 24 hours. This setup was conducted with 7 week old vegetative plants For all treatments leaf tissue from the leaves that experienced egg oviposition and/or larval feeding were collected.
