Search gene expression levels from 20,000+ public Arabidopsis RNA-Seq libraries. RNA-seq has undoubtedly revolutionized the characterization of the small transcriptome, enabling high-throughput profiling and discovery of novel forms of short non-coding RNAs (miRNAs, piRNAs, tRNAs, siRNAs, snoRNA, etc. 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. , 2012) or Araport 11 (Cheng et al. , Jia, J. 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.

A multitude of lncRNAs have been identified by using next-generation sequencing during the last several years, but only a few have been characterized (Xin et al. suecica, we generated RNA sequencing (RNA-seq) data for 15 natural A. In Arabidopsis, mature miRNAs are processed from primary miRNA transcripts (pri-miRNAs) by nuclear HYL1/SE. 1. The AtRTD is a resource that will have immediate utility in analysing Arabidopsis RNA-seq data to quantify differential transcript abundance and expression. RNA-seq was performed as previously described (Liang et al. Briefly, Arabidopsis Col-0 plants were grown at 20°C for 5 weeks, then the temperature was reduced to 4°C.

Comparative single-nucleus RNA-seq analysis captures shared and distinct responses to beneficial and pathogenic microbes in roots. (B) Overview of the construction of Arabidopsis RNA-seq database (ARS). Here, we show, via single-nucleus RNA-seq of developing male gametophytes, that these repressors are critical for. For cpRNA-seq, total RNA was extracted using an RNeasy Plant Mini Kit and subjected to UMI-tagged sequencing, as for scRNA-seq, except that 10 cycles of the PCR amplification step were required. 00959. In order to obtain genome-wide gene expression profiles in the floral meristem at the single-cell level, we use a system for synchronized floral. Three overexpressed lines were pooled as OE lines, and four samples (WT-N and W14-N under normal conditions; WT-D and W14-D under. 62 million raw reads that uniquely mapped to the reference genome (Arabidopsis_thaliana TAIR10. When mapping m 5 C in RNA by using RBS-seq (a modified version of RNA bisulfite sequencing 24), Khoddami et al. For RNA sequencing, total RNA was extracted from pollen and cauline leaf samples using RNA were extracted using the TRizolTM reagent (Life Technologies, Carlsbad, CA) according to the manufacturer’s recommendations. 30. 1 to 5 nanograms (ng) of total RNA isolated from Arabidopsis thaliana (Arabidopsis) embryos and identified a low-cost method with superior performance. This work reconstructed the protophloem developmental trajectory to provide a detailed dissection of cell identity acquisition during tissue maturation. 11. Further studies are needed to better understand the processes involved in U-to-C RNA editing, including the identification of cis or trans regulatory elements,. The Arabidopsis RNA-binding protein FCA requires a lysine-specific demethylase 1 homolog to downregulate FLC. Raw and processed data are available from Ribo-seq/RNA-seq series E-MTAB-7717, RNA-Seq series GSE124003 and ChIP-Seq series GSE127745. & Zhai, J. Illumina RNA sequencing (RNA-Seq) has become an extremely powerful tool for revealing the relationships between genotypes and phenotypes, thereby increasing our understanding of the underlying. S. The RNA-Seq based Arabidopsis gene co-expression network comprised of 54 gene modules. . g. (2020) A comprehensive online database for exploring ∼20,000 public Arabidopsis RNA-Seq libraries. We believe PPRD will help make the transcriptome big. thaliana, rice (Oryza sativa), soybean (Glycine max), maize (Zea mays) as well as non-model species, such as wild strawberry (Fragaria vesca) [32–36]. 2–56. , 2016) has already provided unique insights into the regulation of. The cyp79B2 cyp79B3 (cyp79B2/B3) double. Note that the UBC1 is absent from the nucleoplasm and chromatin. Genome-wide detection of R-loops in Arabidopsis by ssDRIP-seq. Principal component analysis between different Arabidopsis tissues and cell types was based on the mean TPM value of corresponding biological replicates. Here, we introduce the Arabidopsis RNA-seq database (ARS), a free, web-accessible, and user-friendly to quickly explore expression level of any gene in 20,000+ publicly available Arabidopsis RNA. In agreement with Hetzel et al. Here, we performed Direct RNA Sequencing (DRS) using the latest Oxford Nanopore Technology (ONT) with exceptional read length. 6-fold in the central cell, consistent with cell size changes. Here, we adapted mammalian Native Elongation Transcript sequencing and Global Run On sequencing to profile nascent RNA genome. Gene expression was more. 18 . 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 (Parker et al. In the past decades, several methods have been developed for miRNA analysis, including small RNA sequencing (RNA-seq). Here we review the findings and. Thus, we focused on the globular stage, and the pods at 7 DAF were collected for RNA-Seq using the Illumina HiSeq2000 system. Here, we performed whole-genome RNA sequencing to examine the gene expression patterns in Arabidopsis grown under low and high densities.
