(Submitter supplied) SVP is a key MADS-box transcription factor for Arabidopsis development since it acts both during vegetative and reproductive phases where it plays different roles probably by interacting with different partners to regulate specific sets of target genes. In fact, whereas SVP functions as a repressor of floral transition during the vegetative phase, it works as floral meristem gene during reproductive phase. 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 transition to flowering in plants is controlled by a regulatory network that responds to both developmental and environmental signals. The MADS-box genes FLOWERING LOCUS C (FLC) and SHORT VEGETATIVE PHASE (SVP) are major flowering repressors that enhance responses to environmental cues such as winter temperatures, high ambient temperatures and photoperiod. FLC and SVP physically interact in vivo and mutation of each gene causes early flowering while the double mutant is more extreme. more...

(Submitter supplied) The MADS-box transcription factors FLOWERING LOCUS C (FLC) and SHORT VEGETATIVE PHASE (SVP) are major transcriptional repressors controlling flowering time. They enhance responses to environmental cues such as winter temperatures, high ambient temperatures and photoperiod, acting at least in part by blocking transcription of the floral pathway integrators. As other MADS-box transcription factors, FLC and SVP can interact in vivo forming multimeric complexes. 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) The MADS genes encode transcription factors (TF) that act as master regulators of plant reproduction and flower development. The SEPALLATA (SEP) MADS subfamily is not only absolutely required for the development of floral organs, but also plays roles in inflorescence architecture and determinacy of the floral meristem. The SEPs act as organizers of MADS complexes and are able to form both heterodimers and heterotetramers in vitro. more...

(Submitter supplied) Trough a two components inducible system, we expressed ectopically in the SAM a resistant version of AP2 to the regulation of miR172 (AP2m3). The differentially expressed genes by AP2 induction allows the identification of differents groups of genes that could mediate AP2 functions in the SAM.

(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...
