Proper timing for plants to flower under different environmental conditions is critical for their propagation. Light quality is a pivotal environmental cue that plays a critical role in regulating flowering. Plants tend to flower late under light with high red (R)/far-red (FR) light ratio, whereas flower early under light with a low R/FR light ratio. However, how plants fine-tune flowering in response to changes in light quality is not well understood. Here, we demonstrate that the F-box Protein F-box of Flowering 2 (FOF2), an autonomous pathway-related regulator, physically interacts with VASCULAR PLANT ONE-ZINC FINGER 1 and 2 (VOZ1 and VOZ2), which are the direct downstream factors of R/FR light receptor phytochrome B (PHYB)...
