GenomicsOrchestration of Floral Initiation by APETALA1
The MADS-domain transcription factor APETALA1 (AP1) is a key regulator of Arabidopsis flower development. To understand the molecular mechanisms underlying AP1 function, we identified its target genes during floral initiation using a combination of gene expression profiling and genome-wide binding s...

ProteomicsProtein interactions of transcriptional co-regulator LEUNIG_HOMOLOG (LUH) during early stages of Arabidopsis flower development.
To study the formation and dynamics of LUH protein-protein interactions at various stages of flower development, we conducted a series of immunoprecipitation followed by mass spectrometry (IP-MS) experiments using the LUH-GFP in floral induction system (FIS) plant line (pLUH:LUH-GFP pAP1:AP1-GR ap1 ...

ProteomicsIn-vitro Co-immunoprecipitation Mass Spectrometry of LUH and AP1 from Arabidopsis
This dataset contains quantitative co-immunoprecipitation mass spectrometry (Co-IP-MS) data generated to investigate direct interactions between the Arabidopsis co-regulator LUH and the MADS-domain transcription factor AP1. LUH wild type and domain variants (LUH_W, LUH_QW, LUH_LQ) were co-expressed ...

ProteomicsSPOROCYTELESS/NOZZLE interacts with MADS-DOMAIN transcription factors during the megaspore mother cell differentiation in the Arabidopsis ovule
This dataset contains proteomic data from co-immunoprecipitation and mass spectrometry (IP-MS) experiments performed to identify in planta interaction partners of the transcriptional regulator SPOROCYTELESS/NOZZLE (SPL) during Arabidopsis thaliana ovule development. SPL is an essential regulator of ...

GenomicsDevelopmental dynamics of DNA accessibility during flower development [DNaseI-Seq]
Development of eukaryotic organisms is controlled by transcription factors that trigger specific and global changes in gene expression programmes. In plants, MADS-domain transcription factors act as master regulators of developmental switches and organ specification. However, the mechanisms by which...

GenomicsTarget genes of the MADS transcription factor SEPALLATA3, ChIP-seq
The molecular mechanisms by which floral homeotic genes act as major developmental switches to specify the identity of floral organs, are still largely unknown. Floral homeotic genes encode transcription factors of the MADS-box family, which are supposed to assemble in a combinatorial fashion into o...

GenomicsCharacterization of SOC1’s central role in flowering by the identification of its upstream and downstream regulators
The transition from vegetative to reproductive development is one of the most important phase changes in the plant life cycle. This step is controlled by various environmental signals that are integrated at the molecular level by so-called floral integrators. One such floral integrator in Arabidopsi...

TranscriptomicsNO001: Kdm5c controls promoter and enhancer activities
The functional organization of eukaryotic genomes correlates with specific patterns of histone methylations. Regulatory regions in genomes like enhancers and promoters differ in their extent of methylation of histone H3 at lysine-4 (H3K4), but it is largely unknown how the different methylation stat...
