Dynamic coding and noncoding RNA interactions coordinate gene expression during meiosis in wheat

ABSTRACT: We present a high-resolution network of gene expression during meiosis and its regulatory control elements in polyploid wheat. MeioCapture method (Shunmugam et al. 2018 BMC Plant Biology 18: 293) was used for isolating high-purity sporogenous archesporial columns of synchronized male meiocytes from wheat anthers in different meiotic stages. Total RNA extracted from three independent biological replicates per developmental stage of the meiocytes, as well as vegetative flag leaf, young leaves, and reproductive anthers and pollen, was sequenced using Illumina platform, generating 548 million paired-end short mRNA reads. Filtered reads were aligned to the wheat reference genome (IWGSC v1.0) using STAR. Transcript abundance was estimated using the RSEM (v1.3.3) and the IWGSC v1.1 annotation, and read counts and transcripts per million (TPM) values that normalize counts to a consistent number per library (1 million) to facilitate the comparison of relative expression across various samples were generated.

Defining the developmental program leading to meiosis in maize

Project description:We isolated pre-meiotic and early meiotic cells from 24 maize anthers, covering a week of development from the day after archesporial (AR) cell specification to the early zygotene stage of meiotic prophase I. Starting material was staged by anther length, and anther stages were densely sampled from throughout this period. High quality reads were obtained from 144 cells.

Genomic variants affecting homoeologous gene expression dosage contribute to agronomic trait variation in allopolyploid wheat

Project description:We have collected RNA-seq data from the total RNA isolated from the 2-week seedlings of 198 diverse wheat accessions. These accessions were selected among nearly 3,000 lines to represent the broad geographic and genetic diversity of wheat populations. On average, 65.7 million paired-end Illumina reads (2 x 100 bp) were collected for each sample, and after quality trimming were mapped to the wheat reference genome RefSeq v.1.0. The proportion of reads unambiguously mapped to the individual wheat genomes was 81%, with the accuracy of correct read mapping estimated by simulation achieving 98%. The expression levels measured as Transcripts Per Million (TPM) were estimated for high confidence (HC) gene models in the wheat reference genome, with 82,092 gene models (66,333 genes) showing TPM > 0.5 in at least two wheat lines (PRJNA670223)

RNA-seq of SH-SY5Y NB cells stably transduced with shETV5 compared to parental cells, cell line samples and samples of xenografted tumors

Project description:Stable ETV5 knockdown SH-SY5Y were used to investigate the role of ETV5 in vitro and in vivo. Libraries for mRNA sequencing were prepared using the TruSeq stranded mRNA sample prep kit (Illumina), involving polyA-selection, fragmentation, adapter ligation, reverse transcription and PCR amplification. Libraries were quantified using the Qubit 2.0 Fluorometer prior to sequencing with read length of 75 bp on a NextSeq 500 sequencer (Illumina). On average 24.7 M high-quality reads were generated per sample, with a minimal read count of 20.0 M reads for sample 2015_027_009 (sample L105). For each sample, gene-level read counts and KPKM-values were generated with Sailfish (Patro et al. 2014). Read counts are the number of reads overlapping a given feature such as a gene. KPKM-values (K-mers Per Kilobase of exon per Million reads) represent read counts normalized for sequencing depth and transcript length. KPKM-values allow you to compare genes across and within samples.

Pharmacologic IRE1/XBP1s Activation Promotes Systemic Adaptive Remodeling in Obesity

Project description:RNA was isolated from livers of DIO mice treated with IXA4 or vehicle (n=4 per condition) using the Zymo Research Quick-RNA Miniprep Kit according to the manufacturer’s instructions. RNA sequencing was performed by BGI Americas on the BGI proprietary platform (DNBseq), providing single-end 50 bp reads at 20 million reads per sample. Alignment of the sequencing data to the Mus musculus MGSCv37 NCBI build 37.2 was performed using DNAstar Lasergene SeqManPro. Assembled data were then imported into ArrayStar 12.2 with QSeq (DNAStar Inc) to quantify gene expression and normalized reads per kilobase million (RPKM). Differential expression analysis and statistical significance calculations between conditions were assessed using DESeq in R using a standard negative binomial fit for the aligned counts data and are described relative to the indicated control

Small RNA (sRNA), mRNA and SMRT sequencing data from pre-meiotic and meiotic anthers of Lilium Maculatum

Project description:Purpose: To study pre-meiotic (21-nt) and meiotic (24-nt) phasiRNA pathways in non-grass monocots Methods: Anthers were dissected using a 2 mm stage micrometer in a stereo microscope, and immediately frozen in liquid nitrogen until total RNA isolation was performed. Small RNA, mRNA libraries were generated using short-read (Illumina) and Single Molecule Real Time SMRT (PacBio) sequencing approaches. Stages were assigned based on the morphology of archesporial (AR) and tapetal cells of Lilium anthers.

Whole genome transcriptome of in vivo Treg cells and ex vivo TGF-beta induced Treg cells from WT and Aim2 knockout mice

Project description:To understand the whole genome transcriptome of in vivo Treg cells and ex vivo TGF-beta induced Treg cells from WT and Aim2 knockout mice, the total RNA was extracted from indicated Treg cells using the Direct-zol miniprep kit (Zymo Research, R2060). The RNA samples were firstly enriched by Oligo(dT) magnetic beads and used to construct BGISEQ-500 libraries. RNA-seq libraries sequenced using the 50bp single-end protocol (in vivo isolated Treg cells) or 100bp paired-end protocol (TGF-β induced Treg cells) via the BGISEQ-500 sequencer per the manufacturer’s protocol. After filtering of adaptors and low quality reads, clean reads (>26 Million reads per sample for in vivo isolated Treg cells and >40 Million reads per sample for TGF-β induced Treg cells) are mapped to mouse reference genome using HISAT /Bowtie2 tool. Mapping results are stored in BAM files using SAMtools. Total read counts in gene level were summarized using featureCounts function in the Rsubread in R environment, with the R package biomaRt for gene and transcripts mapping. The differential expression (DE) genes were analyzed by DESeq2 package with default setting using total read counts as input, and the adjusted p value (padj) less than 0.05.

A first-in-class, humanized antibody targeting alternatively spliced tissue factor: preclinical evaluation in an orthotopic model of pancreatic ductal adenocarcinoma

Project description:RNA sequencing of 9 samples (3 per group) generated 30 million 150 base long paired end reads revealed differential isoform expression of about 1100 gene transcripts. Hg19 was used as a reference genome for alignment, transcriptome index was created in kallisto using Ensembl cDNA sequences for the reference genome. This index was then used to quantify transcript abundance in raw counts and transcript per million (TPM). We report a suppression in the expression of genes associated with cell cycle regulation (most strongly HBGEF, STN1, ECT2, PLCD3, and RHOC). Suppression of HBGEF and STN1 in hRabMab1 treated tumors was validated by qRT-PCR.
