This short-read RNA sequencing methodology, developed using yeast, revealed that cycloheximide-treated ribosomes protect ∼28-nt regions [ribosome footprints (RFs)] within protein-coding ORFs (). Reports of secondary structures in protein-depleted RNA fractions obtained from Arabidopsis (46, 47) led us to consider that some fragments in the Ribo-seq libraries are derived from regions of ribosome-associated transcripts that are RNase I-resistant due to dsRNA formation. A total of 20 068 publicly available Arabidopsis RNA-seq. However, the amplification step in RNA-seq creates an intrinsic bias against those genes with relatively low expression levels, and therefore does not provide an accurate quantification of all expressed genes. Third, Arabidopsis sperm cells may be transcriptionally active given that abundant transcripts were detected by RNA sequencing (RNA-seq) 29. This section provides a gateway to finding gene expression-related information on Arabidopsis thaliana from high throughput expression data, such as microarrays, GFP-fusion proteins, and Massively Parallel Signature Sequencing technologies. , 2012) or Araport 11 (Cheng et al. .

Here, we present a high-resolution scRNA-seq expression atlas of the Arabidopsis root composed of thousands of independently profiled cells. Virtually all RNA-seq studies provide a snapshot of the steady state transcriptome, which contains valuable information about RNA populations at a given time but lacks information about the dynamics of RNA synthesis and degradation. ABRE are. , 2012]. thaliana have generated multi-omics data (e. The expression of sense FLAIL in different tissues and in response to various abiotic stresses was extracted from the published Arabidopsis RNA-seq database platform (Jia et al, 2020a).

However, most of the current 'RNA-sequencing' technologies produce a relatively short read length and demand a reverse-transcription step, preventing effective characterization of transcriptome complexity. Single-molecule Iso-sequencing of diverse Arabidopsis plant samples. RNA was extracted from leaf material harvested in low light and high light (same material as used for ribosome profiling, RNA-seq, and RNA secondary structure probing with NAI-N 3) by adding 666 µL of extraction buffer (Section 2. We also plan to continue updating PPRD regularly by including new libraries. 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. 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 . 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. Transcriptome sequencing (RNA-seq) is a powerful tool for understanding plant gene expression and screening for stress-resistance genes [18,19,20]. 3. . Expression analysis for miRNA and other genesVideo S1. thaliana reference genome (TAIR10) using STAR (version 020201) (Dobin et al. Genome binding/occupancy profiling by high throughput sequencing Other: Summary: ARABIDOPSIS THRITHORAX-RELATED PROTEINS 5 (ATXR5) AND ATXR6 are required for the deposition of H3K27me1 and for maintaining genomic stability in Arabidopsis. High throughput sequencing results of 12 samples, including hypoxia treatments and multiple controls are summarized in Table 1. thaliana. 2020 Feb;182(2):685-691. 1 A). , 2011; Liu et al. The acyltransferase GPAT5 is required for the synthesis of suberin in seed coat and root of Arabidopsis. The raw and processed data for RNA-seq and smRNA-seq libraries made with RNA extracted from 30 days unopened flower buds of Col-0 and all mutants has been deposited in the. 1 ) for RNA-seq analysis on an Illumina HiSeq 2000 platform. (B) Pearson cross-correlation matrix of the RNA-seq data sets generated in this study alongside sperm RNA-seq data described previously (Borg et al. G. A comprehensive understanding of the A. After isolating polysomes, the sample is treated with ribonuclease to digest unprotected parts of the RNA. 00959. TSS. To fill this gap, we developed the C. The RNA-Seq based Arabidopsis gene co-expression network comprised of 54 gene modules. 6 Gb from a mixed sample; average sequencing depth reached approximately 106×), and yielding 795. The scarcity of plant germline cells has made. The hyperchipable sites were the peaks appeared in multiple ChIP-seq replicates of Col-0. The eFP-Seq Browser displays the number of reads mapped above the desired ARAPORT 11 gene. Transformation of a construct containing ROS1-targeting sgRNA and ROS1-GFP donor sequence into DD45pro::Cas9 lines #58 and #70, but not other promoter::Cas9 lines, gave rise to Southern blot- and. RNA-seq was performed as previously described (Liang et al. The first application was demonstrated in 2005, when small. (A) Data preparation. Data Sources. This study aimed to identify novel stress-responsive genes in plants by performing a meta-analysis of public RNA sequencing (RNA-Seq) data on Arabidopsis. To annotate these modules, we performed enrichment analysis for BP, CC, and MF ontology terms in all of the 54. The Arabidopsis Small RNA Database is a user-friendly, web-based tool for exploring over 2,000 Arabidopsis sRNA-seq libraries. The measured values usually vary by several orders of magnitude, and while the detection of differences at high values is statistically well grounded, the significance of the differences for rare mRNAs can be weakened by the presence of biological and technical noise. , 2019) downloaded from NCBI SRA. 5), which. a, Arabidopsis seedlings were treated with a panel of patterns, and tissue was harvested for RNA extraction at the indicated times.
