Expression data of H2O2 responding genes at Arabidopsis root tip. Arabidopsis thaliana

To identify genes that regulate root development in a hydrogen peroxide devendent manner, we performed a time course microarray analysis of root treated with 1mM H2O2. Overall design: We isolated RNA of non-treated roots and roots treated for 1, 3, and 6 hours. To assess expression responses of proliferating and elongating cells, we dissected each harvested the meristematic and elongation zones of root tips separately.

为鉴定以过氧化氢依赖方式调控根系发育的基因，我们对经1mM过氧化氢（H₂O₂）处理的根系开展了时间序列微阵列分析。实验设计概述：我们分别提取了未处理根系，以及经1小时、3小时和6小时过氧化氢处理的根系总RNA。为评估增殖细胞与伸长细胞的基因表达响应，我们将每份收获样本的根尖分生区与伸长区分开分离。
