ProteomicsA coilin mutant provides a sensitized system for identifying modifiers of alternative splicing and posttranscriptional gene silencing in Arabidopsis thaliana
Coilin is a scaffold protein essential for the structural integrity of Cajal Bodies, which are non-membranous nuclear organelles that are thought to facilitate assembly and maturation of nuclear RNPs, including spliceosomal snRNPs. To investigate further coilin’s functions in plant cells, and to ide...

TranscriptomicsDeep sequencing of small RNAs in the trasngenic wild type plant and the IWR1-type transcription factor mutant, dms4
Full title: Deep sequencing of small RNAs in the trasngenic wild type plant (contains trigger and silencer transgenes) and the IWR1-type transcription factor mutant, dms4 RNA-directed DNA methylation (RdDM) in plants requires two RNA polymerase II (PolII)-related RNA polymerases named PolIV and Pol...

TranscriptomicsAtypical DNA methylation of genes encoding cysteine-rich peptides in Arabidopsis thaliana
In plants, transposons and non-protein-coding repeats are epigenetically silenced by CG and non-CG methylation. This pattern of methylation is mediated in part by small RNAs and two specialized RNA polymerases, Pol IV and Pol V, in a process called RNA-directed DNA methylation. By contrast, many pr...

GenomicsBisulfite-Seq profiling of wild-type Arabidopsis with two-component transgene silencing (T+S) system
In plants, RNA polymerase II (Pol II) transcription of inverted DNA repeats produces hairpin RNAs that are processed by several DICER-LIKE enzymes into siRNAs that are 21-24-nt in length. When targeted to transcriptional regulatory regions, the 24-nt size class can induce RNA-directed DNA methylatio...

GenomicsAn Rtf2 domain-containing protein influences pre-mRNA splicing and is essential for embryonic development in Arabidopsis thaliana
Alternative splicing is prevalent in plants, but little is known about its regulation in the context of developmental and signaling pathways. We describe here a new factor that influences pre-mRNA splicing and is essential for embryonic development in Arabidopsis thaliana. This factor was retrieved ...
