(Submitter supplied) This experiment describes gene expression during early Arabidopsis flower development. We used a 35S:AP1-GR ap1 cal line to induce synchronized flower development by specifically 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 at one-day intervals for the following five days. 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...

(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 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).

(Submitter supplied) Elements for the flower-specific cDNA microarray were obtained from three different sources. First, for those genes that are known or suspected to be involved in flower development, we either amplified fragments of their transcribed regions from cDNA or, if available, obtained cDNA clones from EST clone collections. Second, we generated cDNA libraries using RNA extracted from different floral tissues. more...
