| 1 | In this study, we show that FHY3 and FAR1, two homologous proteins essential for phytochrome A-mediated light signaling, physically interact with and repress the DNA binding activity of EIN3 (a key transcription factor essential for ethylene signaling) and PIF5 (a bHLH transcription factor negatively regulating light signaling), and interfere with their DNA binding to the promoter of ORE1, which encodes a key NAC transcription factor promoting leaf senescence. | ethylene | FRS (FAR1 Related Sequences) transcription factor family | Arabidopsis thaliana |
| 2 | Our combined results suggest that FHY3 and FAR1 act in an age gating mechanism to prevent precocious leaf senescence by integrating light and ethylene signaling with developmental aging. | ethylene | FRS (FAR1 Related Sequences) transcription factor family | Arabidopsis thaliana |
