Project description:Proteomic Analysis of the total proteome from Arabidopsis thaliana SUMO E3 Ligase mutants siz1-2 and mms21-1 and wild-type (Col-0) 8-day old seedlings
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: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:Transcriptional profiling of arsenic-induced toxicity and tolerance in Arabidopsis plants of different ecotypes Arsenic (As) is a toxic metalloid found ubiquitously in the environment and has widely been known as an acute poison and carcinogen. As toxicity is a major factor leading to root growth inhibition in plants. However, the molecular mechanisms of plants in response to As has not been extensively characterized. In this study, Arabidopsis ecotypes that are As-tolerant (Col-0) and -sensitive (Ws-2) were used to conduct a transcriptome analysis of the response to As (V). To begin elucidating the molecular basis of As toxicity and tolerance in Arabidopsis, seedlings of Col-0 and Ws-2 were subjected to As treatment. The root elongation rate of Col-0 was significantly higher than that of Ws-2 when exposed to As. The tolerant ecotype (Col-0) demonstrated lower accumulation of As when compared to the responses observed in the sensitive Ws-2. Subsequently, the effect of As exposure on genome-wide gene expression was examined in the two ecotypes. Comparative analysis of microarray data identified groups of genes with common and specific responses to As between Col-0 and Ws-2. The genes related to heat responses and oxidative stresses belonged to common responses, indicating conserved stress-associated changes across two ecotypes. The majority of specific responsive genes were those encoding heat shock proteins, heat shock factors, ubiquitin and transporters. The data suggested that metal transport and maintenance of protein structure may be important mechanisms for toxicity and tolerance to As. This study presents comprehensive surveys of global transcriptional regulation and identifies stress- and tolerance-associated genes in response to As.
Project description:Chromatin immunoprecipitation was performed in nlp2-2 Arabidopsis thaliana Col-0 14-d-old seedlings complemented by a pNLP2::NLP2-GFP construct upon 30 minutes NO3- resupply after a 3-day NO3- starvation.
Project description:Four-day old seedlings of Arabidopsis wildtype Col-0, T-DNA insertional mutant ataf2-2, and overexpression line ATAF2ox-3 were collected for total RNA extraction. Three biological replicates were prepared for each genotype.
Project description:Ten-day old seedlings of Arabidopsis wildtype Col-0, and SsE1-overexpressing lines SsE1-GFP-5 and SsE1-GFP-8 were collected for total RNA extraction. Three biological replicates were prepared for each genotype.
Project description:In this Data Report, we provide an immunoprecipitation (IP)-based analysis of the HDA19 interactome in etiolated Arabidopsis seedlings. We believe that the interactome presented here provides a valuable resource for follow-up research on novel interacting partners of this central protein. The material used for this experiment was derived from hypocotyls of 6-day-old etiolated Arabidopsis seedlings. The dataset contains a total of 6 files, 3 independent biological replicates of each Col-0 (control plants) and 35S::HDA19-GFP plants.
Project description:To explore the bivalent histone modifications in the Arabidopsis genome, we examined genome-wide histone 3 lysine-27 trimethylation (H3K27me3) and histone 3 lysine-4 trimethylation (H3K4me3) in 5-day-old seedlings (Col-0) by ChIP-seq. We found that more than 1300 genes loci contain both H3K27me3 and H3K4me3.
