Project description:1-day-old seedlings of Col-0 and vil1-1 were performed RNA-Seq to identify differentially expressed genes caused by VIL1 mutation in Arabidopsis
Project description:To analyze the molecular mechanism behind the relationship between Arabidopsis leaf maturation and de novo root regeneration, we carried out an RNA-seq analysis using detached first-pair rosette leaves before culturing (time 0) and 1 d after culturing (DAC) from 9-, 12- and 15-d-old Col-0 seedlings. We first analyzed gene expression levels in the leaves before detachment (at time 0) from the three developmental states. Changes in gene expression could be grouped into six clusters. Many genes were upregulated or downregulated during leaf maturation. Next, we analyzed gene expression levels in the leaf explants from 9- and 15-d-old seedlings at 1 DAC compared with gene expression levels at time 0. By comparing up- or downregulated genes (1 DAC vs time 0) between leaves from 9- and 15-d-old seedlings, we found that many of the genes were particularly up- or downregulated only in immature leaves or only in mature leaves after 1 d of culturing.
Project description:Transcriptome-wide analysis of gene expression using detached first-pair rosette leaves before culture (time 0) and 1 day after culture (DAC) from 9-day-old, 12-day-old and 15-day-old Col-0 seedlings
Project description:To reveal the molecular mechanism during de novo root regeneration from Arabidopsis leaf explants cultured on B5 medium without exogenous hormones, we carried out an RNA-seq experiment using detached leaf explants with partial petiole before culture (i.e. time 0) and 2 d after culturing (DAC) from12-d-old Col-0 seedlings. Gene expression of the wounded region (including the partial petiole and some surrounding tissues), which comprises regeneration-competent cells, was analyzed.
Project description:We determined the transcriptomes of hda9-1, pif4-2 and wild type Col-0 seedlings of 2 day old and 7 day old, at control and high temperature conditions (22oC vs 27oC), in short day (8h) photoperiod
Project description:Col-0 floral stem was grafted on the msh1 mutant (Col-0/msh1); on the dcl2,3,4,msh1 quadruple mutant (Col-0/dcl2,3,4,msh1); on Col-0 (Col-0/Col-0). Seeds were collected from the grafted Col-0 scion after grafts were established. Seed coming from the graft then were grown on the peat mix, leaf tissue was collected at the bolting and used for the total RNA sequencing.
Project description:Transcriptional profiling of 60h-old Arabidopsis whole seedlings comparing control Col-0 wild-type plants with pifQ mutant plants The expression profile of dark-grown pifQ mutant shows similar pattern of Rc-grown Col-0 wild-type Keywords: Genetic modification
Project description:Compared analysis of the transcriptomes of 12-day old seedlings from wild type Col-0 treated with NO for 15, 30 and 60 min vs untreated control seedlings. Samples were harvested 12 h after dawn of day 12 after sowing and seedlings were grown under long days (16 h light / 8 h darkness) photoperiodic conditions.
Project description:Col-0 floral stem was grafted on the msh1 mutant (Col-0/msh1); on the dcl2,3,4,msh1 quadruple mutant (Col-0/dcl2,3,4,msh1); on Col-0 (Col-0/Col-0). Seeds were collected from the grafted Col-0 scion after grafts were established. Seed coming from the graft then were grown on the peat mix, leaf tissue was collected at the bolting and used for the bisulfite sequencing (methylome). Tissue from the msh1 mutant and dcl2,3,4,msh1 quadruple mutants used as rootstocks was similarly collected at the bolting stage and used for the bisulfite sequencing.
