Plants must perceive and rapidly respond to changes in ambient temperature for their successful reproduction. Here we demonstrate that Arabidopsis SHORT VEGETATIVE PHASE (SVP) plays an important role in the response of plants to ambient temperature changes. The loss of SVP function elicited insensitivity to ambient temperature changes. SVP mediates the temperature-dependent functions of FCA and FVE within the thermosensory pathway. SVP controls flowering time by negatively regulating the expression of a floral integrator, FLOWERING LOCUS T (FT), via direct binding to the CArG motifs in the FT sequence. We propose that this is one of the molecular mechanisms that modulate flowering time under fluctuating temperature conditions.

• Regulation and function of SOC1, a flowering pathway integrator. (2010, background): “However, SVP interacts with FLC to form a floral repressor complex and directly binds to the promoters of SOC1 and FT for transcriptional repression (Lee et al., 2007; Li et al., 2008).”
• H2A.Z-containing nucleosomes mediate the thermosensory response in Arabidopsis. (2010, positive): “Acceleration of flowering in response to higher temperature requires genes in the autonomous pathway (Blazquez et al., 2003) and is dependent on increasing expression of FLOWERING LOCUS T (FT) (Balasubramanian et al., 2006; Cerdan and Chory, 2003; Halliday et al., 2003; Lee et al., 2007).”
• Seasonal and developmental timing of flowering. (2010, background): “SVP binds to FT and SOC1 – the same targets as FLC (Lee et al., 2007; Li et al., 2008).”
• The control of developmental phase transitions in plants (2011, background): “Low temperatures may have a mild positive effect on a few MIR156 loci but none of the known ambient temperature pathway components (Lee et al., 2007) seems to affect miR156 accumulation (Lee et al.”

• Common mechanisms regulate flowering and dormancy (2009, background): “However, SVP is primarily involved in ambient temperature regulation of FT [27] whereas FLC plays a more prominent role in the vernalization response.”
• miR156-regulated SPL transcription factors define an endogenous flowering pathway in Arabidopsis thaliana. (2009, positive): “FLC forms a complex with another MADS domain protein, SHORT VEGETATIVE PHASE (SVP), and together they repress not only FT but also the FT target SOC1 (Lee et al., 2007; Li et al., 2008).”
