What is Exploring PIF4's contribution to early flowering in plants under daily variable temperature and its tissue‐specific flowering gene network about?
## Abstract Molecular mechanisms of how constant temperatures affect flowering time have been largely characterized in the model plant Arabidopsis thaliana; however, the effect of natural daily variable temperature outside laboratories is only partly explored. Several flowering genes have been shown to play important roles in temperature responses, including PHYTOCHROME‐INTERACTING FACTOR 4 (PIF4) and FLOWERING LOCUS C (FLC), the two genes encoding for the transcription factors (TFs) that act antagonistically to regulate flowering time by activating and repressing floral integrator FLOWERING LOCUS T (FT), respectively. In this study, we have taken a multidisciplinary approach to explore the contribution of PIF4 to the early flowering observed in the daily variable temperature (VAR) and to broaden its transcriptional network using publicly available transcriptomic data. We observed early flowering in the natural accessions Col‐0, C24 and their late flowering hybrid C24xCol grown under VAR, as compared with a constant temperature (CON). The loss‐of‐function mutation of PIF4 exhibits later flowering in VAR in both the Col‐0 parent and the C24xCol hybrid, suggesting that PIF4, at least
