(Submitter supplied) The emerging picture of transcriptional regulation is one of unexpected complexity. It is now clear that single transcription factors control hundreds, if not thousands, of direct targets by binding their genomic loci, but it is not understood how many of these are major players and how many are supporting cast. To address this, we leverage a well-characterized developmental network in Arabidopsis and map genome-wide binding of related proteins in multiple tissues. more...

(Submitter supplied) The floral transition in Arabidopsis is tightly controlled by complex genetic regulatory networks in response to endogenous and environmental flowering signals. SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1) and SHORT VEGETATIVE PHASE (SVP), two key MADS-domain transcription factors, perceive these signals and function as antagonistic flowering regulators. To understand how they mediate the floral transition, we mapped in vivo binding sites of SOC1 and SVP using chromatin immunoprecipitation followed by hybridization to whole-genome tiling arrays (ChIP-chip). more...

(Submitter supplied) 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 organ-specific multimeric protein complexes. Major mediators of protein interactions are MADS-domain proteins of the SEPALLATA subfamily, which play a crucial role in the development of all types of floral organs. more...

(Submitter supplied) This experiment describes gene expression after the activation of APETALA1-GR, to study and identify AP1 target genes. We used a 35S:AP1-GR ap1 cal line to induce a synchronized response activating the AP1-GR fusion protein in ap1 cal inflorescence-like meristems through dexamethasone treatment. Tissue samples were collected immediately after the treatment, as well as subsequent timepoints. The expression profiles of the individual samples were then analyzed by gene expression profiling using whole-genome oligonucleotide arrays (non-commercial; Meyerowitz Lab Arabidopsis Operon Array v4). more...

(Submitter supplied) 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 studies. Many of its targets encode transcriptional regulators, including known floral repressors. The latter genes are down-regulated by AP1, suggesting that it initiates floral development by abrogating the inhibitory effects of these genes. more...

We used a 35S:AP1-GR ap1 cal line to induce a synchronized response activating the AP1-GR fusion protein in ap1 cal inflorescence-like meristems through dexamethasone or dexamethasone+cycloheximide treatment. Tissue samples were collected at 3hrs after the treatment. The expression profiles of the individual samples were then analyzed by gene expression profiling using whole-genome oligonucleotide arrays (Agilent, custom-commercial).
