Combinatorial activities of SHORT VEGETATIVE PHASE and FLOWERING LOCUS C define distinct modes of flowering regulation in Arabidopsis

(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...

Combinatorial activities of SHORT VEGETATIVE PHASE and FLOWERING LOCUS C define distinct modes of flowering regulation in Arabidopsis

(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...

Genome-Wide binding sites of two MADS-domain transcription factors SOC1 and SVP in Arabidopsis during the floral transition

(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...

Functional characterisation of SVP by a Chromatin Immunoprecipitation sequencing approach

(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...

Divergence of regulatory networks governed by the orthologous transcription factors FLC and PEP1 in Brassicaceae species.

(Submitter supplied) Genome-wide landscapes of transcription factor (TF) binding sites (BSs) diverge during evolution, conferring species-specific transcriptional patterns. The rate of divergence varies in different metazoan lineages but has not been widely studied in plants. We identified the BSs and assessed the effects on transcription of FLOWERING LOCUS C (FLC) and PERPETUAL FLOWERING 1 (PEP1), two orthologous MADS-box TFs that repress flowering and confer vernalization requirement in the Brassicaceae species Arabidopsis thaliana and Arabis alpina, respectively. more...

Characterization of SOC1’s central role in flowering by the identification of its upstream and downstream regulators

(Submitter supplied) 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 Arabidopsis (Arabidopsis thaliana) is the MADS domain transcription factor SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1). more...

Temperature-dependent alternative splicing of FLM controls flowering in Arabidopsis thaliana

(Submitter supplied) How plants control the transition to flowering in response to ambient temperature is only beginning to be understood. In Arabidopsis thaliana, the MADS-box transcription factor genes FLOWERING LOCUS M (FLM) and SHORT VEGETATIVE PHASE (SVP) have key roles in this process. FLM is subject to temperature-dependent alternative splicing, producing two splice variants, FLM-β and FLM-δ, which compete for interaction with the floral repressor SVP. more...

VASCULAR PLANT ONE-ZINC FINGER1 (VOZ1) and VOZ2 interact with CONSTANS in photoperiodic control of flowering

(Submitter supplied) In plants, endogenous and environmental signals such as light control the timing of the transition to flowering . Two phytochrome B-interacting transcription factors, VASCULAR PLANT ONE–ZINC FINGER1 (VOZ1) and VOZ2 redundantly promote flowering in Arabidopsis thaliana. In the voz1 voz2 mutant the expression of FLOWERING LOCUS C (FLC) was up-regulated and expression of FLOWERING LOCUS T (FT) was down-regulated, which was proposed to be the cause of late flowering in voz1 voz2. more...

Global transcriptome analysis identifies genes regulated by FT in the leaf

(Submitter supplied) Flowering of Arabidopsis thaliana is accelerated by several environmental cues, including exposure to long days. The photoperiod-dependent promotion of flowering involves the transcriptional induction of FLOWERING LOCUS T (FT) in the phloem of the leaf. FT encodes a mobile protein that is transported from the leaves to the shoot apical meristem, where it forms part of a regulatory complex that induces flowering. more...

Analysis of the Arabidopsis shoot meristem transcriptome during floral transition identifies distinct regulatory patterns and an LRR protein that promotes flowering

(Submitter supplied) We sequenced cDNA synthesized from mRNA from 3 time points of a time course of Arabidopsis thaliana shoot apical meristems. Plants were grown two weeks in short days (time point +0LD) and then exposed to long days for 1 day (time point +1LD) and 3 days (time point +3LD). Meristem cells were collected using laser capture microdissection, to generate a meristem-specific time course of gene expression in the early stages of floral induction. more...

H3K27me3 and H3K4me3 profiles in chr4/pkr1 and WT [ChIP-seq]

(Submitter supplied) Several pathways conferring environmental flowering responses in Arabidopsis converge on developmental processes that act in the shoot apical meristem to mediate the floral transition. Many characterized mutations impair environmental flowering responses, however downstream developmental processes have been more refractory to mutagenesis. We constructed a quintuple mutant in which several environmental pathways are impaired and showed that its flowering responses to changes in photoperiod and ambient temperature are almost abolished. more...

Identifying targets of FLC at 27oC

(Submitter supplied) FLOWERING LOCUS C (FLC) is a MADS box transcription factor that plays a well characterised role in repressing the vegetative to floral transition of Arabidopsis thaliana. FLC has also been shown to affect the Arabidopsis circadian clock, with mutant seedlings showing short circadian periods. In a previous study, we identified the temperature-dependent circadian period QTL PerCv5b near the FLC locus on the top arm of Chromosome 5. more...
