Eight-day-old Arabidopsis seedlings, grown under long-day conditions (16/8 h light/dark), were transferred to continuous light or kept under the same light/dark conditions for an. This work reconstructed the protophloem developmental trajectory to provide a detailed dissection of cell identity acquisition during tissue maturation. applied a plate-based scRNA-seq method, Switch Mechanism at the 5′ End of RNA Templates (Smart-seq), to profile 19 Arabidopsis root phloem cells. Arabidopsis thaliana transcriptomes have been extensively studied and characterized under different conditions. 51), and the expression levels were calculated with rsem-calculate-expression. Further, differentially expressed genes (DEGs) were. -B. High-throughput RNA-seq analyses of transcriptome dynamics in Arabidopsis plants following infection with virulent DC3000 or ETI-triggering avirulent Pst strains (AvrRpt2 and AvrRpm1) showed that transcriptional response to avirulent pathogens was really fast, already observed at 4 hpi, whereas the equivalent response to virulent Pst was much. thaliana, B. In order to obtain genome-wide gene expression profiles in the floral meristem at the single-cell level, we use a system for synchronized floral. After sequence reads from an RNA sequencing (RNA-seq) experiment are mapped to a de novo transcriptome or reference genome, for example the TAIR10 (Lamesch et al. Here, we performed whole-genome RNA sequencing to examine the gene expression patterns in Arabidopsis grown under low and high densities. , 2009 ) with the parameter “. The mapping of. , 2020). TSS. RNA-seq was performed in triplicate for WT Col-0, sob3-6, SOB3-D, and pif4 pif5 pif7. The libraries were sequenced on a BGI MGISEQ-2000 instrument with 2 × 150 bp reads. The shoot apical meristem allows for reiterative formation of new aerial structures throughout the life cycle of a plant. A total of 45.
