In our study we have used RNA sequencing to uncover the cold responsive non-coding RNA repertoire in A. After isolating polysomes, the sample is treated with ribonuclease to digest unprotected parts of the RNA. This section provides a gateway to finding gene expression-related information on Arabidopsis thaliana from high throughput expression data, such as microarrays, GFP-fusion proteins, and Massively Parallel Signature Sequencing technologies. suecica accessions, 15 closely related A. , 2018). 5-EU was added to the liquid MS and incubated for 24 h. However, interpreting results obtained by these sequencing methods is fragmented, and an overview is needed. Recently, RNA sequencing (RNA-seq) has been widely used to mine stably expressed genes for use as references in RT-qPCR. Recently, pioneering studies applied droplet-based single-cell RNA sequencing (scRNA-seq) to the Arabidopsis root and demonstrated the utility of this technology to identify new cell-type markers, examine gene expression dynamics across pseudotime, and identify regulators that control cell-type-specific responses to environmental conditions. The expression of REF6, ELF6, JMJ13, and PRC2 subunits during embryogenesis was extracted from the published datasets (Schneider et al. Here, we investigated the nascent RNA and mature messenger RNA (mRNA) from plant leaf tissues exposed to 5 min of heat shock treatment using global run-on sequencing and RNA sequencing methods.
