(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...

(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...

(Submitter supplied) Two aspects of light are very important for plant development: the length of the light phase or photoperiod and the quality of incoming light. Photoperiod detection allows plants to anticipate the arrival of the next season, whereas light quality, mainly the red to far-red ratio (R:FR), is an early signal of competition by neighbouring plants. phyB represses flowering by antagonising CO at the transcriptional and post-translational levels. more...

(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...

(Submitter supplied) We report the application of single-molecule-based sequencing technology for high-throughput profiling of JMJ28 in 14 days old arabidopsis. By obtaining sequence from chromatin immunoprecipitated DNA, we generated genome-wide JMJ28-binding maps of 14 days old arabidopsis. To reveal bound genes by JMJ28, chimeric protein JMJ28-3xFLAG was expressed under JMJ28 promoter in jmj28 (JMJ28pro:JMJ28:3xFLAG/ jmj28). more...

(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...
