Leaves from WT and transgenic Arabidopsis plants were collected under normal and drought stress (without watering for 5 days) conditions. About TAIR The Arabidopsis Information Resource (TAIR) maintains a database of genetic and molecular biology data for the model higher plant Arabidopsis thaliana. RNA-seq library preparation. , 2020) with the addition of microspore RNA-seq data (Wang et al. 1 to 5 nanograms (ng) of total RNA isolated from Arabidopsis thaliana (Arabidopsis) embryos and identified a low-cost method with superior performance. Abstract. 18 . Through the analysis of cis-acting promoter elements, 8-bp-long ABRE, PyACGTGGC, was identified in the promoter in 82% of dehydration-responsive genes in Arabidopsis (Maruyama et al. (B) coverage of DRN1 (At2g45180), a gene repressed by elevated salt concentrations. The RNA-Seq based Arabidopsis gene co-expression network comprised of 54 gene modules. For example, FACS was mainly applicable to model plants, such as arabidopsis. Experiments with read length equal or larger than 50 nucleotides were shortlisted based on biological interest, trying to. The RNA-seq raw reads were aligned to TAIR10 genome using Bowtie2 (v2. To determine whether changes in open chromatin regions were associated with changes in gene expression in rice under heat stress, we integrated ATAC-seq data with RNA-seq data analysis. 6 million. All compressed files were extracted with “fastq-dump” with default parameters. -Uk. Plants may respond to unfavorable conditions by accelerating reproductive processes like flowering. 1A). 9) indicating that plant scRNA-seq is highly sensitive.
