ARR1 regulated genes in the lateral root cap. ARR1 regulated genes in the lateral root cap

We sorted for GFP+ cells using the enhancer trap line J2632 with the UAS promoter driving the expression of an inducible (by dexamethasone - Dex) constitutive active version of the ARR1 gene (ARR1ΔDDK). We obtained the transcriptional profile of lateral root cap cells Overall design: Seedlings were grown for 5 days. Time-course expression profiling at 3 time points: J2632-UAS::ARR1ΔDDK-GR untreated (T0), 1 hour (T1) and 4 hour (T2) Dex-treated. J2632-UAS::ARR1ΔDDK-GR sorted fluorecent cells were harvested for RNA extraction.
