Previous short-read based nascent RNA sequencing methods, such as pNET-seq, plaNET-seq, and GRO-seq have been applied in Arabidopsis [39–42] and in other plants including cassava and maize , are mostly developed for detecting Pol II-associated elongating RNAs, and can also detect RNA signal downstream of poly(A) site. salsugineum (hereafter Arabidopsis, Brassica, Camelina, Eutrema) with the goal of detecting the full suite of lincRNAs, including those with low-expression and/or. To this end, we performed a meta-analysis of microarray data from a variety of cytokinin-treated samples and used RNA-seq to examine cytokinin-regulated gene expression in Arabidopsis (Arabidopsis thaliana). To determine the similarity in sequence binding preferences between maize TFs and Arabidopsis TFs, we contrasted the top 1% k-mers to the collection of DAP-seq PWMs using TOMTOM from the MEME. To determine whether changes in open chromatin regions were associated with changes in gene expression in rice under heat stress, we integrated ATAC-seq data with RNA-seq data analysis. Sci.

Third, Arabidopsis sperm cells may be transcriptionally active given that abundant transcripts were detected by RNA sequencing (RNA-seq) 29. Although specific databases designed to manage the RNA-Seq data of these two plants have been available, the detection of AS events from the RNA-Seq data are often overlooked. Small RNA-seq enables genome-wide profiling and analysis of known, as well as novel, miRNA variants.

Here, we integrate mRNA sequencing, genome-wide RNA polymerase II (RNPII), chromatin immunoprecipitation sequencing, and DNase sequencing datasets to establish the relationship between RNPII occupancy and chromatin accessibility in response to NO 3 − treatments in Arabidopsis roots. For Col-0, high mappability of the 150 bp single-end Illumina reads to the Col-0 reference genome or transcriptome was found for all seven alignment tools, ranging from 95. Eight-day-old Arabidopsis seedlings, grown under long-day conditions (16/8 h light/dark), were transferred to continuous light or kept under the same light/dark conditions for an. and intact RNA is fed through the nanopore by a motor protein (Garalde et al. , 2006; Ponting et al. RNA-seq_hid1_rep3 This SubSeries is part of SuperSeries: GSE181489: The DREAM complex antagonizes WDR5a and represses the productive elongation of transcription in. We identified specific groups of differentially. Plant J 59:163–168 Berry S, Hartley M, Olsson TSG, Dean C, Howard M (2015) Local chromatin environment of a Polycomb target gene instructs its own epigenetic inheritance. Single-cell RNA sequencing (scRNA-seq) is a powerful approach to investigate cell- and developmental stage–specific responses to stimuli, but most previous studies have focused on a single time point. Samples were harvested every 3 hours. The first application was demonstrated in 2005, when small. 11. Zhang, H. The constructs were transformed into Arabidopsis thaliana Col-0 and pif7-1 plants using the floral dip method. L. Based on the 34 genomes listed in the Phytozome database, we performed a genome-wide BLAST search using Arabidopsis ABF1, AREB1/ABF2, AREB2/ABF4, and ABF3 amino acid sequences. In Arabidopsis, other genes expressed in FM comprise AGP18, which encodes a plasma membrane-attached glycosylated protein, and ATH1 (Arabidopsis Thaliana Homeobox 1), a BEL1-like homeodomain (HD. Here, we introduce the Arabidopsis RNA-seq database (ARS), a free, web-accessible, 16 and user-friendly to quickly explore expression level of any gene in 20,000+ publicly available 17 . We integrate the single-cell ATAC-seq (scATAC-seq) data with published single-cell RNA-seq (scRNA-seq) profiles of the same tissue to obtain automated annotations of cells in our. (B) Overview of the construction of Arabidopsis RNA-seq database (ARS). It is estimated by DNA Affinity Purification with high throughput sequencing (DAP-seq) that bZIP11 contains DNA-binding sites in over 7,000 genes in Arabidopsis, which is nearly one third of the. Here, we performed whole-genome RNA sequencing to examine the gene expression patterns in Arabidopsis grown under low and high densities. Identification and analysis of AREB/ABF family in plants. Kukurba KR, Montgomery SB. The RNA-seq analysis identified a number of differentially expressed genes (DEGs) (log 2. Contributor(s) Favero DS, Sugimoto K: Citation(s) 32197081: Submission. & Zhai, J. RNA-seq data of Arabidopsis thaliana have been considered for this investigation. Our previous Arabidopsis RNA‐seq database (ARS) has been updated recently, and the number of libraries has been increased from 20 068 to 28 164 (Zhang. We compared the performance of three low-input mRNA sequencing (mRNA-seq) library preparation kits on 0. Estrada A, Patel K, Qin P (2013) RNA-seq of Arabidopsis pollen uncovers novel transcription and alternative. We collected Arabidopsis RNA-Seq datasets published till March, 2019 from GEO, DDBJ, EBI, and SRA database using keywords — ”((Arabidopsis thaliana[Organism]) AND "transcriptomic"[Source]) AND "rna seq"[Strategy]”. Protoplasting-free large-scale single-nucleus RNA-seq reveals the diverse cell types in Arabidopsis root. A family, was significantly induced in the saur32 mutant. Briefly, Arabidopsis Col-0 plants were grown at 20°C for 5 weeks, then the temperature was reduced to 4°C.
