2-week-old Arabidopsis seedlings (Columbia ecotype)

ABSTRACT: Comparison of TopHat alignments and assessment of spurious splice junctions for 32nt and 76nt read lengths. Total RNA from 2-week-old Arabidopsis thaliana (ecotype Columbia) seedlings grown on MS plates was isolated using RNeasy Plant Mini Kit from Qiagen. To remove any contaminating DNA, RNA was treated with DNAse. Isolation of poly (A) mRNA and preparation of cDNA library were carried out using the Illumina TrueSeq RNA kit. Sequencing (72 cycle) was done on Illumina Genome Analyzer II. 2 replicates

SpliceGrapher: detecting patterns of alternative splicing from RNA-Seq data in the context of gene models and EST data.

Rogers Mark F MF Thomas Julie J Reddy Anireddy Sn AS Ben-Hur Asa A

Genome biology 20120131 1

We propose a method for predicting splice graphs that enhances curated gene models using evidence from RNA-Seq and EST alignments. Results obtained using RNA-Seq experiments in Arabidopsis thaliana show that predictions made by our SpliceGrapher method are more consistent with current gene models than predictions made by TAU and Cufflinks. Furthermore, analysis of plant and human data indicates that the machine learning approach used by SpliceGrapher is useful for discriminating between real and ...[more]

The SNF2 and RING domain proteins FRG1 and 2 are required for RNA-directed DNA methylation in Arabidopsis [mRNA-Seq]

Project description:DNA methylation in Arabidopsis thaliana is maintained by at least four different enzymes: MET1, CMT3, DRM2, and CMT2. However, DNA methylation is established exclusively by the enzyme DRM2, which acts in the RNA-directed DNA methylation (RdDM) pathway. Some RdDM components belong to gene families and have partially redundant functions, such as DICER-LIKE 2, 3 and 4, and IDN2- LIKE 1 and 2. Traditional mutagenesis screens usually fail to detect genes if they are redundant, since the loss of one gene can be compensated by a related gene. In an effort to circumvent this issue, we utilized co-expression data to identify closely related genes that are co-regulated with genes in the RdDM pathway. Here we report the discovery of two redundant proteins, SNF2-RING-HELICASE-LIKE1 and 2 (FRG1 and 2) that are putative chromatin-related paralogous proteins. Analysis of genome–wide bisulfite sequencing shows that simultaneous mutations of FRG1 and 2 cause broad defects in methylation at RdDM targeted loci. We also show that FRG1 stably associates with Su(var)3-9-related SUVR2, a known RdDM component, in vivo. Combined, our results identify FRG1 and FRG2 as novel components of the RdDM machinery. mRNA profiles of 14 days old seedlings of Columbia 0 wild type and frg1-1 frg2-1 double mutants, 3 biological replicates each.

Genome-wide identification of Hfq-regulated small RNAs in the bacterial pathogen Erwinia amylovora

Project description:RNA-seq analysis was performed to examine the sRNA transcripts in wild type E. amylovora 1189 and in the deletion mutant of hfq, at 6 and 12 hours of culture in hrp-inducing minimal medium. Total RNA was isolated from wild type Ea1189, and the hfq mutant of Ea1189, at 6 and 12 hours post inoculation in hrp-inducing minimal medium. RNA transcripts that are between 50-350 nucleotides were analyzed by RNA-seq. Intergenic transcripts whose expression was greatly reduced in the hfq mutant than the wild type at both 6 and 12 hours post inoculation in hrp-inducing minimal medium were selected as potential small RNAs.

Analysis of Pro-Inflammatory Gene Activation and RNA Processing by RNAseq of Nascent Transcripts [supplement]

Project description:Note: These datasets are in supplement to, but separate from, Geo GSE32916. We examined pro-inflammatory gene activation in activated wildtype and IFNAR-/- murine macrophages by performing RNA-Seq with poly(A) enriched transcripts. This experimental strategy allowed a global, high-resolution analysis of the transcriptional regulation of diverse classes of co-expressed genes and allowed us to identify co-expressed gene classes that may depend on IFN-signaling for its expression. The results provide quantitative insights into the relationship between transcription and distinct promoter and chromatin properties.

Selective Functions of Individual Zinc Fingers Within the DNA-Binding Domain of Ikaros (RNA-seq: sorted DP thymocytes)

Project description:The C2H2 zinc finger is the most prevalent DNA-binding motif in the mammalian proteome, with DNA-binding domains usually containing more tandem fingers than are needed for stable sequence-specific DNA recognition. To examine the reason for the frequent presence of multiple zinc fingers, we generated mice lacking finger 1 or finger 4 of the 4-finger DNA-binding domain of Ikaros, a critical regulator of lymphopoiesis and leukemogenesis. Each mutant strain exhibited a specific subset of the phenotypes observed with Ikaros null mice. Of particular relevance, fingers 1 and 4 contributed to distinct stages of B- and T-cell development and finger 4 was selectively required for tumor suppression in thymocytes and in a new model of BCR-ABL+ acute lymphoblastic leukemia. These results, combined with transcriptome profiling (this GEO submission: RNA-Seg of whole thymus from wt and the two ZnF mutants), reveal that different subsets of fingers within multi-finger transcription factors can regulate distinct target genes and biological functions, and they demonstrate that selective mutagenesis can facilitate efforts to elucidate the functions and mechanisms of action of this prevalent class of factors.

Regulation of Gene Expression Dynamics during Developmental Transitions by the Ikaros Transcription Factor

Project description:The DNA-binding protein, Ikaros, functions as a potent tumor suppressor and hematopoietic regulator. However, the mechanisms by which Ikaros functions in the nucleus remain largely undefined, due in part to its atypical DNA-binding properties and partnership with the poorly understood Mi-2/NuRD complex. In this study, we extended our analysis of thymocyte development and lymphomagenesis in a mouse strain containing a specific deletion of Ikaros zinc finger 4, which exhibits a select subset of abnormalities observed in Ikaros null mice. By examining thymopoiesis in vivo and in vitro, numerous abnormalities were observed. RNA-sequencing revealed that each developmental stage is characterized by mis-regulation of a limited number of genes, with a strong preference for genes modulated in a stage-specific manner. Strikingly, individual genes and pathways rarely exhibited Ikaros-dependence at all developmental stages. Instead, the most consistent feature of aberrantly expressed genes was a reduced magnitude of expression level change during a developmental transition. These results and others suggest that Ikaros may not be a dedicated and consistent activator or repressor of a defined set of genes. Instead, its primary function may be to support the dynamic range of gene expression changes during developmental transitions via atypical molecular mechanisms that remain undefined.

Photomorphogenesis of Arabidopsis seedlings is accompanied by complex alternative splicing alterations

Project description:We analyzed transcriptome-wide gene expression and AS changes in etiolated Arabidopsis seedlings exposed to red, blue, and white light. Our study revealed that different types of light signals trigger rapid AS responses of numerous genes, including splicing factors and other functional groups. Among these candidates was RRC1, which was previously shown to function in PHYB signaling. The light signaling phenotype of an rrc1 mutant could only be complemented with the splicing variant being up-regulated upon light exposure, indicating a self-reinforcing circuit. Finally, we provide evidence that light-regulated AS can occur in a phytochrome-independent manner and is closely intertwined with the plantâ??s energy status. Analysis of alternative splicing patterns of dark-grown Arabidopsis seedlings exposed for 1 or 6 hours to white, blue, or red light, or kept in darkness; all samples in duplicates
