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. et al. The schematic depicts an RG4 with three layers of G-quartets (G3 RG4, guanine (G) coloured in orange), with the loop length of any nucleotide (N, coloured in grey), potassium ions (K +, grey. 55% of the total 18–30-nt reads in Arabidopsis plants , in contrast with an average of 0. FEBS Lett. 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. The treated RNA samples were deep-sequenced, resulting in a total of 181. Arabidopsis RNA-Seq Database. Our database includes over 57,000 plant public RNA-seq libraries, comprising 25,283 from Arabidopsis, 17,789 from maize, 10,710 from rice, and 3,974 from soybean, and covers a total of 1. (Recommended access method) Arabidopsis RNA-seq Database. Further analysis revealed that changes in density influenced metabolism-. (Recommended access method) Arabidopsis RNA-seq Database. Comparative single-nucleus RNA-seq analysis captures shared and distinct responses to beneficial and pathogenic microbes in roots. Introduction. Plotted is. (2020) A comprehensive online database for exploring ∼20,000 public Arabidopsis RNA-Seq libraries. 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 . , 2019). 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. Studies in Arabidopsis has revealed that CTS efficiency is. 101-113. 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. 5-EU was added to the liquid MS and incubated for 24 h.
