Transcriptomic analysis of Col and arf7 responding to auxin

Project description:The goal of this study is to clarify the function of ARF7 in the pathway of auxin inducing lateral root development. We isolated total RNA from the roots of 8-day-old Col-0 and arf7 seedlings. New genes act downstream of ARF7 after responding to auxin treatment, during the lateral root formation, are discovered.

Transcriptomic analysis of Col and arf7 responding to auxin in hypocotyl

Project description:The goal of this study is to clarify the function of ARF7 in the pathway of auxin inducing the process responding to gravity in hypocotyl. We isolated total RNA from the hypocotyls of 4-day-old Col-0 and arf7 seedlings that were grown in the darkness. New genes act downstream of ARF7 after responding to auxin treatment, responding to gravity, are discovered.

Gene expression analysis of Arabidopsis root in LBD16-GR overexpression line

Project description:Lateral roots (LRs) are formed post-embryonically and contribute to root architecture formation in vascular plants. LATERAL ORGAN BOUNDARIES-DOMAIN 16 (LBD16) is a key transcription factor to initiate LR formation. LBD16 functions downstream of AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19, and overexpression of LBD16 partially restores LR formation in the absence of ARF7 and ARF19. To identify downstream targets of LBD16, we engineered a transgenic line with inducible LBD16 activity by overexpressing a fusion protein of LBD16 and rat glucocorticoid receptor (GR) in arf7 arf19 mutant. Here we identified primary response genes of LBD16 from transcriptome analysis of 35Spro:LBD16:GR arf7 arf19 line.

Auxin mediated gene expression in WT and arf2-6 mutant

Project description:Global gene expression data from 7-day old light-grown liquid cultured seedlings treated with or without auxin (5µM IAA) for 2 h. Columbia (WT) and Auxin response factor 2 (ARF2) T-DNA insertion mutant (arf2-6 ) were used for this study. Each experimental condition has three true replicates for a total of 12 hybridizations. Data analysis: Affymetrix GeneChip Microarray Suite version 5.0 software was used to obtain signal values for individual genes. The data files containing the probe level intensities (cell files) were used for background correction and normalization using the log2 scale robust multi-array analysis (RMA) procedure (Irizarry et al., 2003). The “R” environment (Ihaka and Gentleman, 1996) was used for running the RMA program. Data analysis and statistical extraction were performed using log2 converted expression intensity data within Microsoft Excel 98. Based on preliminary analysis, a hybridization signal less than 5.64385619 (= log2 50) was considered as background; all signals less than 5.64385619 were converted to 5.64385619 prior to further analysis.

Nucleo-cytoplasmic partitioning of ARF proteins controls auxin responses in Arabidopsis thaliana

Project description:The phytohormone auxin plays crucial roles in nearly every aspect of plant growth and development. The AUXIN RESPONSE FACTOR (ARF) family of transcription factors regulates auxin-responsive gene expression and exhibit nuclear localization in regions of high auxin responsiveness. Here we show that activating ARF7 and ARF19 proteins accumulate in micron-sized assemblies within the cytoplasm of tissues with attenuated auxin responsiveness. The intrinsically disordered middle region and the folded PB1 interaction domain of ARFs drive protein assembly formation. Mutation of a single lysine within the PB1 domain abrogates cytoplasmic assemblies, promotes ARF nuclear localization, and results in an altered transcriptome and morphological defects. Our data suggest a model in which ARF nucleo-cytoplasmic partitioning regulates auxin responsiveness, thus providing a mechanism for cellular competence for auxin signaling.

Transcription profiling by array of Arabidopsis wild type and an ARF7/ARF19 double knockout mutant roots dissected into 5 developmental zones

Project description:Arabidopsis seedlings, of both wild-type and an ARF7/ARF19 double knockout mutant, were grown to 7 days post-germination. The roots were then dissected into 5 developmental zones, the meristem, early elongation zone, late elongation zone, mature root and lateral root zone. The sections then underwent transcriptional profiling to identify processes and regulatory events specific and in common to the zones.
