Project description:Gibberellin (GA) Treatment of Arabidopsis Root Tips
| PRJNA124153 | ENA
Project description:The plant hormone gibberellin (GA) represents an important regulator of growth and development. Early transcriptional events controlled by GA are not well characterised. Previous microarray studies have identified genes responsive to GA treatment in the whole seedling. The whole seedling represents many tissues where subtle effects of GA treatment in specific tissues may be masked. When treated with GA, an effect on the growth rate of roots was observed. More specifically, the shorter root of a GA-deficient plant can be rescued to wild-type length by the application of GA. This experiment was designed to identify GA-regulated genes in the root tips of Arabidopsis. The use of a GA-deficient mutant provides a greater potential to identify genes responding to GA treatment. Root tips are ideally suited for the quick uptake of the hormone treatment. There will be two biological replicates which will each consist of a control treatment at 0 minutes and 2 hours, as well as the experimental GA-treated 2 hour time point. This system provides an opportunity to compare gene expression between treated and non-treated root tips and allow the identification of early GA-responsive genes.

Project description:This experiment was set up in order to identify the (direct) transcriptional targets of the Ethylene Response Factor 115 (ERF115) transcription factor. Because ERF115 expression occurs in quiescent center (QC) cells and strong effects on the QC cells were observed in ERF115 overexpression plants, root tips were harvested for transcript profiling in order to focus on root meristem and QC specific transcriptional targets.

Project description:Preceding hypoxia by an ethylene treatment improves root tip survival. To identify key players and processes mediating ethylene enhanced tolerance, the transcriptomic response of root tips was investigated directly after ethylene or control pretreatment, 2 and 4 hours of subsequent hypoxia, and 1 hour of reoxygenation. Seedlings were 4 days or 7 days old and grown on MS plates without added sugar. Only the root tips were harvested

Project description:This experiment was set up in order to identify the (direct) transcriptional targets of the Ethylene Response Factor 115 (ERF115) transcription factor. Because ERF115 expression occurs in quiescent center (QC) cells and strong effects on the QC cells were observed in ERF115 overexpression plants, root tips were harvested for transcript profiling in order to focus on root meristem and QC specific transcriptional targets. Wild-type (Col-0 ecotype), erf115 mutant (SALK_021981) and ERF115 overexpressing (p35S:ERF115 ORF) root tips (three replicates each) were harvested and subjected to transcript profiling, using the Col-0 samples as control reference.
