The PIF4 transcription factor promotes stem elongation by inducing auxin biosynthesis at elevated temperature in Arabidopsis. Here, Lee et al.show that the RNA-binding protein FCA attenuates PIF4 activity by promoting its dissociation from the promoter of a gene encoding an auxin biosynthetic enzyme.
