Potato StCOL1 peaks at dawn and, in contrast to Arabidopsis AtCO, is phyB stabilized
StCOL1 directly activates the FT-like StSP5G repressor in long-day conditions
StCOL1 binds a conserved TGTGGT element in the StSP5G promoter
StSP5G negatively regulates expression of the StSP6A mobile signal in leaves
