J. et al. 3: PIF7 directly activates the warm temperature transcriptome in response to daytime thermal cycles. We use single-cell RNA sequencing to define the cellular taxonomy of the Arabidopsis vegetative shoot apex at the transcriptome level. History. Yeast and Arabidopsis thaliana transcriptomes have been profiled by RNA-Seq approaches concurrently with this study 15,16,17, but the mouse and human genomes are much larger and more complex than. . The comparative analysis of Arabidopsis RNA-seq is shown in Figure S3. Here, we describe the detailed experimental procedure using Illumina sequencing to analyze the expression profiles of smRNAs and mRNAs in Arabidopsis. 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. In comparison with the EST data that provided the bulk of the TAIR10 annotation, the RNA-Seq data offer single-base resolution and more precise measurement of levels of transcripts and their isoforms (Wang et al. 1C), suggesting there are fewer unstable transcripts and introns in Arabidopsis. In this research, a strand-specific RNA sequencing (ssRNA-seq) was used to explore the dynamic changes in the transcriptome landscape of Arabidopsis thaliana. Here, we comparatively explore the transcriptomes of three leaf tissues (epidermis, mesophyll, vasculature) after induction of diverse stress pathways by chemical stimuli (antimycin A, 3-amino-1,2,4-triazole, methyl viologen, salicylic acid) and ultraviolet light in Arabidopsis using laser capture microdissection followed by RNA sequencing. Endosperm, the primary site of gene imprinting in. et al. The RNA-seq analysis identified a number of differentially expressed genes (DEGs) (log 2. In our study we have used RNA sequencing to uncover the cold responsive non-coding RNA repertoire in A. We have downloaded an Arabidopsis dataset from NCBI for this purpose. In Arabidopsis, mutation of PAF1C. (B) Overview of the construction of Arabidopsis RNA-seq database (ARS). After sequence reads from an RNA sequencing (RNA-seq) experiment are mapped to a de novo transcriptome or reference genome, for example the TAIR10 (Lamesch et al. To complement our RNA-seq analysis and investigate differences in protein abundance in not4a vs WT in more detail, we carried out a quantitative proteomics analysis of total protein extracts from. PLoS One 10,. Analysis and comprehensive comparison of Pacbio and Nanopore-based RNA-sequencing in Arabidopsis transcriptome. RNA-seq data from 7- and 22-day-old Arabidopsis shoots cultured under a 12:12-h light/dark cycle were obtained 1, 7, 13, and 19 h after the lights were turned. RNA-Seq by Expectation-Maximization (RSEM) tool was used to calculate abundance estimation and expression value of each transcript 56. Some data contributed by: Steve. In a different approach, Roszak et al. By combining fluorescence-activated nucleus sorting and laser-capture microdissection with next-generation RNA sequencing, we characterized the transcriptomes of xylem vessels,. In Arabidopsis, laser capture microdissection (LCM) combined with microarray or RNA-seq was commonly used to study gene expression changes in female gametophytic cells [63,64,65], which could result in datasets with mRNA cross-contamination among different cell types . Detailed methods are described below. The resulting RNA-seq datasets. A. Deep sequence analysis of the root transcriptome. Since TAIR10, around 200 Arabidopsis thaliana RNA-Seq studies have been published and deposited in NCBI SRA. RNA- seq analysis of Arabidopsis inoculated with RSV To investigate the transcriptional responses of the Arabidopsis plants to RSV, RNA from three plants from each treatment were mixed to construct 4 cDNA libraries (RSV-14 dpi, RSV-21 dpi, Mock-14 dpi, Mock-21 dpi, Fig.
