Data Sources. , 2017) versions of the Arabidopsis thaliana genome, the resulting SAM (sequence alignment/map) or BAM. 62 million raw reads that uniquely mapped to the reference genome (Arabidopsis_thaliana TAIR10. b Incompletely spliced and fully spliced fractions of the Nanopore reads from our single-nucleus RNA library, compared with a previously published total RNA library. As shown in panel A, the simulated/real data are then directly mapped to the. The Arabidopsis root has a simple structural and functional organization consisting of concentric cylinders of cell layers with radial symmetry. Gene expression was more diverse in seedling, and genes involved in cell wall biogenesis were highly expressed in pollen. Arabidopsis MBD5, MBD6, and SILENZIO act as TE repressors downstream of DNA methylation. Here, we established the first-ever large-scale splicing efficiency database in any organism. RNA-Seq analysis of transgenic Arabidopsis. When plotting the average of logarithmic normalized mean counts of each transcript in the RNA-seq data set versus transcripts in the RIP-seq data, we saw an overall positive correlation between RNA-seq counts and RIP-seq counts (Additional file 1: Figure S5a). Here, we generated time-series RNA-sequencing (RNA-seq) data to compare temporal transcriptome dynamics of Arabidopsis Col-0 and combinatorial mutants of dde2, ein2, pad4, and sid2 during infection with virulent Pto DC3000 or ETI-triggering avirulent Pto DC3000 expressing AvrRpt2 or AvrRpm1 (348 samples in total). (2020) A comprehensive online database for exploring ∼20,000 public Arabidopsis RNA-Seq libraries. RNA sequencing and analysis. PLoS One 10,. Fig. To annotate these modules, we performed enrichment analysis for BP, CC, and MF ontology terms in all of. (A) Schematic representation of the 5-EU pulse-chase experiment. We found that Pol II tends to accumulate downstream of the transcription start site (TSS). Arabidopsis stress data sets were obtained from Zeller et al. PacBio Iso-seq was performed on total RNA extracted from nineteen samples from different Arabidopsis Col-0 organs, developmental stages, abiotic stress conditions, infection with different pathogens and RNA degradation mutants to capture a broad diversity of transcripts (Additional File 1: Table S1). S1 A ). Small RNAs (sRNAs) are short RNA molecules, usually non-coding, involved with gene silencing and the post-transcriptional regulation of gene expression. The x axis represents the year of data generation, and the y axis is the number of sequenced bases in GB. The RNA-seq data of 40 samples from leaf and silique tissues of multi genotypes of Arabidopsis in the present study were from our previous study, including the overexpression of AtLEA, AtVOC, RNAi of AtVOC, and AtLEA mutant (Liang et al. Arabidopsis thaliana (Col-0) and SA-related mutants (all in the Col-0 background), eds16-1, npr1-1, and pad4-1 were used. So, we carried out. RNA Sequencing of Arabidopsis thaliana Seedlings after Non-Thermal Plasma-Seed Treatment Reveals Upregulation in. Plants were grown for 5 d in liquid MS medium. In order to determine poly-A + and sRNA expression of Arabidopsis roots and their changes in response to nitrate, we grew plants in hydroponic nitrate-free medium with 0. . Consistently, Nanopore RNA -seq data of 79 chromatin -associated RNAs provided no evidence for splicing at the FLAIL locus [30] (Fig. 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. Contact us. Here, we performed whole-genome RNA sequencing to examine the gene expression patterns in Arabidopsis grown under low and high densities. A combination of lineage tracing, single-cell RNA-seq and live imaging has unveiled that Arabidopsis root tip restoration upon resection follows an embryonic pathway (Efroni et al. Sci. To address this challenge, here we present the Arabidopsis Small RNA Database (ASRD), an online database with integrated, multifaceted functions for exploring published Arabidopsis (Arabidopsis thaliana) sRNA-seq libraries . Since TAIR10, around 200 Arabidopsis thaliana RNA-Seq studies have been published and deposited in NCBI SRA.
