The Arabidopsis RNA binding protein SERRATE (SE) is best known for its function in primary miRNA processing. The hyperchipable sites were the peaks appeared in multiple ChIP-seq replicates of Col-0. 1101/844522 EID: 2-s2. In this research, a strand-specific RNA sequencing (ssRNA-seq) was used to explore the dynamic changes in the transcriptome landscape of Arabidopsis thaliana. thaliana transcription. , 2017) versions of the Arabidopsis thaliana genome, the resulting SAM (sequence alignment/map) or BAM (binary alignment/map) files may be explored with genome browsers that display. Arabidopsis thaliana transcriptomes have been extensively studied and characterized under different conditions. Since TAIR10, around 200 Arabidopsis thaliana RNA-Seq studies have been published and deposited in NCBI SRA. and F. Identification and analysis of AREB/ABF family in plants.
