Illumina sequencing of chromatin-associated RNA has been used to study CTS in Arabidopsis [18, 19] and soybean [17]. Zhang, H. 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-cell RNA-seq in general and Smart-seq2 in particular is a method primarily developed for mammalian cells that are much larger (10–100 µm), and thus assumingly with a higher cellular content (including RNA) than Arabidopsis sperm cells with a size of ~ 2.

RNA-seq and ChIP-seq data analysis Detailed methodology for RNA-seq and ChIP-seq data analysis are provided in Supplementary Notes 1 and 2. Garcia-Ruiz, H. Although specific databases designed to manage the RNA-Seq data of these two plants have been available, the detection of AS events from the RNA-Seq data are often overlooked. The Arabidopsis pooled RNA (quantity ≥ 10 µg, concentration 20 ng µl –1) and genomic DNA were subjected to next-generation genome and transcriptome sequencing (DNA- and RNA-seq, respectively). , 2019) and 236 rice RNA-seq data sets (Wang et al. However, interpreting results obtained by these sequencing methods is fragmented, and an overview is needed. In Arabidopsis ( Arabidopsis thaliana ), PM II occurs before anthesis, so that three-celled pollen grains (a vegetative cell and two sperm cells within the vegetative cell cytoplasm) are later released from the anthers ( Dumas et al. To this end, we performed a meta-analysis of microarray data from a variety of cytokinin-treated samples and used RNA-seq to examine cytokinin-regulated gene expression in Arabidopsis (Arabidopsis thaliana). We used a standardized pipeline to re-process the raw data, map the reads to the pepper's genome, and count the. 4. For RNA sequencing, nine cDNA libraries from three treatments (0, SPD and SPM) of algal samples for 24 h under 30°C were used to generate 391 million PE reads. Liu, F. We find that the shoot apex is composed of highly heterogeneous cells, which can be. Arabidopsis thaliana is a long established model species for plant molecular biology, genetics and genomics, and studies of A. , 2020). ABRE are. Related to Figs. Long non-coding RNAs are a class of ncRNAs with a length longer than 200 nucleotides and poor protein-coding potential (Pang et al. Based on these data, we. and intact RNA is fed through the nanopore by a motor protein (Garalde et al. (B) coverage of DRN1 (At2g45180), a gene repressed by elevated salt concentrations. Dimensionality reduction for visualizing single-cell data using UMAP. The potential of our single-nucleus RNA sequencing method is shown through the characterization of transcriptomes of seedlings and developing flowers from Arabidopsis thaliana. , 2020) with the addition of microspore RNA-seq data (Wang et al. Lastly, the eFP-Seq Browser tool (BAR) permits the visualization of 113 RNA-seq data sets used to create the ARAPORT 11 reannotation of the Arabidopsis genome (Cheng et al. We integrate the single-cell ATAC-seq (scATAC-seq) data with published single-cell RNA-seq (scRNA-seq) profiles of the same tissue to obtain automated annotations of cells in our. Coverage of merged RNA-seq samples was normalised to the effective Arabidopsis genome size and visualised using the Integrative Genomics Viewer. Primer-dependent and primer-independent initiation of double stranded RNA synthesis by purified Arabidopsis RNA-dependent RNA polymerases. 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 Arabidopsis gene co-expression network constructed based on entire collection of Arabidopsis RNA-Seq datasets at NCBI thus represents a multitude of genotypes and conditions for A.
