The epidermis coordinates thermoresponsive growth through the phyB-PIF4-auxin pathway
Abstract
The PIF4 transcription factor along with the phyB photoreceptor, regulates growth responses to elevated temperature in plants. Here the authors show that PIF4 expression in the epidermis, rather than the vasculature, stimulates auxin responses and thermoresponsive growth in Arabidopsis.
