Project description:In order to elucidate the role of the Arabidopsis thaliana LLM-domain B-GATAs in response to high light intensities, a transcriptomic analysis of Col-0, a hexuple LLM-domain B-GATA mutant hex (gnc gnl gata15 gata16 gata17 gata17l) and GNLox under high-ligh stress conditions was performed.
Project description:ChIP-seq of GNL/GATA22 of Arabidopsis thaliana (35S::GNL:YFP:HA:GR gnc gnl, after treatment 4 hours with 10 μM Dexamethasone and Mock)
Project description:Genome-wide target genes of PPD2 were identified through ChIP-seq on Arabidopsis cell cultures. For ChIP-seq, PPD2 was fused to the GSyellow TAP tag and expressed from the 35S promoter. The p35S:PPD2-GSyellow construct was transformed into Arabidopsis thaliana PSB-D cell culture. ChIP was performed using anti-GFP antibody (abcam290).
Project description:SLIM1 has a well established role in regulating transcriptional responses to sulfur deficiency in Arabidopsis thaliana. In order to investigate the impact of SLIM1 expression under sufficient nutrient conditions, we generated 35S::SLIM1 over-expression lines. SLIM1OX plants were found to have larger rosette area, bolt earlier, and enter developmental senescence earlier than Col-0 and slim1KO (slim1-cr) plants. RNA-seq followed by differential expression analysis was performed on rosette tissue at three timepoints.
Project description:We performed chloroplast ChIP-seq (cpChIP-seq) to identify the possible DNA-binding sites of mTERF5 in Arabidopsis thaliana. To this end, we generated transgenic Arabidopsis plants expressing mTERF5 carrying an HA tag under the control of the CaMV 35S promoter. Then, We used the polyclonal antibody (abcam, ab9110, lot GR304617-8 ) against HA tag which conjugated to ChIP-Grade protein A/G agarose (Thermo scientific, 26161, lot QJ223903) to perform cpChIP assay. The obtained chromatin immunoprecipitated DNA of chloroplasts were used to build DNA libaries for high-throughput sequencing. Finally, we showed that three potenssial DNA regions across the chloroplast genome compared to the control group were enriched by mTERF5.
