About TAIR The Arabidopsis Information Resource (TAIR) maintains a database of genetic and molecular biology data for the model higher plant Arabidopsis thaliana. The immediate downstream targets of ANT and AIL6/PLT3 in flowers are unknown, however. CrossRef CAS. A clear enrichment in coding sequence reads in the input nuclear RNA-seq data over that of the FLAG:AGO4 RNA-IP seq data further validates the reliability of our data. 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. However, most of the current ‘RNA. 1 to 5 nanograms (ng) of total RNA isolated from Arabidopsis thaliana (Arabidopsis) embryos and identified a low-cost method with superior performance. Single-cell RNA sequencing (scRNA-seq) has emerged as a powerful technique for mapping and examining individual cell behaviors in multicellular organisms, providing new insights into developmental trajectories, cell type specificity, and identities. Sample Collection for RNA-Seq. Total RNA was isolated using the RNeasy Plant Mini Kit (QIAGEN, 74,904). 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. The preprocessing of RNA-Seq data and IR event identification with ASTool. 1 – 2 and and6 6 – 7, S1–S2, S4–S6, and STAR Methods.
