The most common experimental approach for studies of flowering transition involves growing plants under. However, a detailed understanding of how oscillations in mRNA levels are connected to oscillations in post-transcriptional processes, such as splicing, has remained a challenge. thaliana, rice (Oryza sativa), soybean (Glycine max), maize (Zea mays) as well as non-model species, such as wild strawberry (Fragaria vesca) [32–36]. J. Recently, pioneering studies applied droplet-based single-cell RNA sequencing (scRNA-seq) to the Arabidopsis root and demonstrated the utility of this. We used plant native elongating transcript sequencing and global run-on sequencing to profile nascent RNAs genome wide in Arabidopsis. et al. In Arabidopsis, elevated temperature has been shown to increase root elongation by regulating Brassinosteroid (BR) signaling 30. In the central cell of tetraploid plants, DEMETER (DME) is upregulated, which. ABRE are. 8) with default parameters in local alignment mode. While RNA-seq has had the greatest impact of these high-throughput sequencing technologies, the CrY2H-seq method (Trigg et al. In the central cell of tetraploid plants, DEMETER (DME) is upregulated, which. et al. thaliana transcription. 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. Plant 13, 1231–1233 (2020). 2. 1 , 3 , 5 , Supplementary Figs. RNASeq for Model Plant (Arabidopsis thaliana) This tutorial will serve as a guideline for how to go about analyzing RNA sequencing data when a reference genome is available. Fig. RNA-Seq data from the Arabidopsis thaliana accessions Col-0 and N14 were mapped with five alignment-based and two pseudo-alignment tools. Here, we identified 6,510 lncRNAs in Arabidopsis under normal or stress conditions. 2020 Feb;182(2):685-691. All compressed files were extracted with “fastq-dump” with default parameters. 1b, 1b, lower. Natl. Identification of cytokinin-responsive genes using microarray meta-analysis and RNA-Seq in Arabidopsis. We found the candidate ABFs in only 29 land plants, including moss, lycophyte,. et al. . 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. 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 resulting ribosome-protected RNA fragments (or ribosome foot-prints) are used to generate a sequencing library (Ribo-seq) (Fig.
