Fig 9. Working model for the regulation of heading time in wheat.

Fig 9

The model integrates photoperiod and vernalization signals into the regulation of FT1 expression in wheat leaves. FT1 is then transported to the shoot apical meristem (dotted green arrow) where it induces the transition from the vegetative to the reproductive phase. Blue arrows indicate promotion of gene expression or activity and red lines ending in a crossed-bar indicate repression. ELF3, LUX and ELF4 proteins form the evening complex, which binds to the PPD1 promoter and inhibits its transcription. The complex interactions between VRN2 and CO1, CO2 and PPD1 [5] are not included in the figure for clarity.
