TANDEM ZINC-FINGER/PLUS3 (TZP) is a recently characterized novel key component of light signal transduction in plants. Accumulating evidence indicates that TZP plays an important role in multiple processes of light-mediated plant growth and development. TZP acts as a negative regulator of blue light signaling, regulates phytochrome B (phyB)-dependent control of photoperiodic flowering, and is required for the phosphorylation of the far-red light photoreceptor phyA in vivo. Further investigation and full elucidation of the biochemical activity and regulatory mechanisms of TZP will not only provide new insights into the light signaling networks, but also facilitate the design and breeding of new crop varieties with ideal plant architecture and more efficient usage of solar energy. In this review, we systematically summarized the current understanding of the role of TZP in regulating light signaling pathways in plants, and discussed the important questions for further study on TZP functions.
