The association between gene expression and whole genome histone H3K4 mono-, di, and trimethylation: expression data. Arabidopsis thaliana

These microarrays are part of a study where a comparison was made between the change in transcription and H3K4 mono-, di-, and tri-methylation levels (via ChIP-seq) in the Arabidopsis thaliana genome when plants are subjected to water deficit stress. Water deficit stress causes a large number of genes to change their transcript levels, which provided a large set of genes to examine for corresponding chromatine changes. Keywords: stress response Overall design: Arabidopsis thaliana RNA was isolated from control (watered) and treatment (water-deficit) samples for analysis on microarrays with three biological reps.

本批基因微阵列（microarrays）隶属于一项研究，该研究针对拟南芥（Arabidopsis thaliana）基因组，对比分析了植物遭受水分亏缺胁迫时的转录水平变化，以及H3K4单甲基化、二甲基化与三甲基化水平的变化（上述甲基化水平通过染色质免疫共沉淀测序（ChIP-seq）检测）。水分亏缺胁迫可诱导大量基因的转录水平发生改变，这为探究对应染色质变化提供了充足的基因数据集。关键词：胁迫响应（stress response）。实验设计：从对照组（正常浇水）与处理组（水分亏缺）的样本中提取拟南芥RNA，开展基因微阵列分析，每组设置3次生物学重复。
