Induced and natural variation of promoter length modulates the photoperiodic response of FLOWERING LOCUS T.

Abstract excerpt

FLOWERING LOCUS T (FT) regulates the floral transition in many plant species by integrating environmental seasonal signals and internal cues. Here we show that two interdependent regulatory regions are necessary and sufficient to convey photoperiod responsiveness to FT. While a minimal distance between the regulatory regions is required to fully suppress FT expression under short days, increased distance reduces...
