TranscriptomicsTranscription profiling of Arabidopsis wild type or mp mutant seedlings treated with auxin
Comparison of mp mutant seedlings with transgenics carrying a dexamethasone-inducible GR-bodenlos gene. Seedlings were pretreated with control medium or medium containing dexamethasone, followed by a 1 hour auxin treatment, and expression profiles were compared using Affymetrix ATH1 arrays.

TranscriptomicsTranscriptional profiles between mp mutant seedlings and transgenics carrying the dexamethasone-inducible GR-bdl protein
In order to identify targets of the transcription factor AUXIN RESPONSE FACTOR5 / MONOPTEROS (ARF5/MP), we compared transcriptomes of mp-B4149 mutant seedlings (9 day-old) and seedlings carrying the dexamethasone-inducible version of the MP inhibitor protein BODENLOS (GR-bdl). Without dexamethasone ...

TranscriptomicsIntegration of growth and patterning during vascular tissue formation in Arabidopsis
Coordination of cell division and pattern formation is central to tissue and organ development, and is particularly important in plants where walls prevent cell migration. Auxin and cytokinin are both critical for division and patterning, but it is unknown how these hormones converge to control tiss...

ProteomicsThe plant hormone auxin triggers distinct and rapid phosphorylation responses in Chara braunii
The plant hormone auxin (indole-3-acetic acid (IAA) ) regulates plant morphology and development in land plants. Moreover, it was regently shown that auxin can trigger rapid changes in phospho-proteomes of land plants and unicellular algae, suggesting an deeply conserved ancient role of auxin as an ...

Auxin Phospho-proteomics Algae 
ProteomicsThe central mediator of auxin-triggered phosphorylation in plants is a RAF-like kinase.
The plant signaling molecule auxin triggers both fast and slow cellular responses across the plant lineage, including both land plants and algae. We discovered an ultra-fast proteome-wide phosphorylation response to auxin across 5 land plant and algal species, converging on a core group of shared ta...

ProteomicsThe plant hormone auxin triggers an ultra-fast proteome-wide response.
The plant signaling molecule auxin controls growth and development through a simple nuclear pathway that regulates the expression of numerous genes. There are however several cellular and physiological responses to auxin that occur within seconds, far too rapid to be mediated by gene expression chan...

ProteomicsABP1-TMK auxin perception mediates rapid phosphorylation for regeneration and auxin canalization
The phytohormone auxin triggers transcriptional reprograming utilizing a well-characterized nuclear perception machinery. In contrast, mechanisms underlying other auxin effects, such as auxin feed-back on its transport, rapid regulation of ion fluxes or ultrafast global phospho-response, remain enig...

TranscriptomicsTranscriptome analysis of genes regulated by INDEHISCENT (IND) transcription factor under the control of the 35S promoter after treatment with auxin
IND is a regulator of fruit development in Arabidopsis thaliana. To identify genes regulated by IND we performed array based transcriptome analysis of Dexamethasone (DEX) inducible IND transgenic seedlings. One week old 35S::IND:GR seedlings were treated with DMSO, Auxin, DEX and Auxin plus DEX for ...
