• The transcription factor FLC confers a flowering response to vernalization by repressing meristem competence and systemic signaling in Arabidopsis. (2006, background): “Expression of FT in the phloem was previously shown to promote early flowering (An et al. 2004; Abe et al. 2005).”
• Photoperiodic flowering of Arabidopsis: integrating genetic and physiological approaches to characterization of the floral stimulus (2005, background): “However, CO is approximately 20 kDa larger than GFP and expression of GFP:CO from the SUC2 promoter complemented the co2 mutation, but GFP fluorescence was only detected in the vascular tissue and not in the meristem or leaf epidermal cells (An et al. 2004).”
• FT protein acts as a long-range signal in Arabidopsis. (2007, background): “Additionally, in a study in Brassica napus, a close relative to Arabidopsis thaliana, FT protein could be identified among other potential signaling proteins by analysis of the soluble fraction of the sieve-tube exudates of FT mRNA is specifically localized to the SUC2 promoter expression domain.”
• CONSTANS and the CCAAT Box Binding Complex Share a Functionally Important Domain and Interact to Regulate Flowering of Arabidopsis[W][OA] (2006, background): “At HAP3a and CO are both regulated by GI, and CO is expressed in the phloem, where it acts to promote flowering through activation of FT transcription (An et al., 2004; Ayre and Turgeon, 2004).”
• Regulation of flowering time: all roads lead to Rome (2011, background): “The CONSTANS (CO) gene encodes a putative zinc finger transcription factor [33], the temporal and spatial regulation of which turned out to be key to the photoperiod-dependent induction of flowering (Table 1) [34].”
• Regulation and identity of florigen: FLOWERING LOCUS T moves center stage. (2008, background): “Indeed, these experiments indicate that the signal must reside downstream of FT transcription (3, 86).”
• miR156-regulated SPL transcription factors define an endogenous flowering pathway in Arabidopsis thaliana. (2009, neutral): “To explore the tissue requirement of SPLs, we made use of plants that misexpress miR156 from the SUC2 promoter in phloem companion cells, the site of FT action (An et al., 2004; Takada and Goto, 2003), or in FD-expressing cells at the shoot apex.”
• Seasonal and developmental timing of flowering. (2010, background): “either in leaves or the SAM, and this promotion of flowering does not require CO activity (An et al., 2004).”
