Basic helix‐loop‐helix (bHLH) family transcription factor PHYTOCHROME INTERACT‐ ING FACTOR 4 (PIF4) is necessary for plant adaption to light or high ambient temperature. PIF4 directly associates with plenty of its target genes and modulates the global transcriptome to induce or reduce gene expression levels. However, PIF4 activity is tightly controlled by its interacting pro-teins. Until now, twenty‐five individual proteins have been reported to physically interact with PIF4. These PIF4‐interacting proteins act together with PIF4 and form a unique nexus for plant adap-tion to light or temperature change. In this review, we will discuss the different categories of PIF4‐interacting proteins, including photoreceptors, circadian clock regulators, hormone signaling com-ponents, and transcription factors. These distinct PIF4‐interacting proteins either integrate light and/or temperature cues with endogenous hormone signaling, or control PIF4 abundances and transcriptional activities. Taken together, PIF4 and PIF4‐interacting proteins play major roles for exog-enous and endogenous signal integrations, and therefore establish a robust network for plants to cope with their surrounding environmental alterations.
