In this research, a strand-specific RNA sequencing (ssRNA-seq) was used to explore the dynamic changes in the transcriptome landscape of Arabidopsis thaliana exposed to cold temperatures (4°C). To illustrate its utility, ChloroSeq was applied to published RNA-Seq datasets derived from Arabidopsis thaliana grown under control and abiotic stress conditions, where the organellar transcriptome had not been examined. The x axis represents the year of data generation, and the y axis. 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. Taking advantage of the existing temperature transcriptomes, from both expression microarray and RNA sequencing (RNA-seq), we have gathered, re-normalized, and unbiasedly re-analyzed the integrated transcriptomic profiles of Arabidopsis thaliana subjected to a wide range of temperature conditions and treatments, ranging from freezing, cold, low.
