Abstract Leaves of shade-avoiding plants such as Arabidopsis (Arabidopsis thaliana) change their growth pattern and position in response to low red far-red ratios (LRFRs) encountered dense plant communities. Under LRFR, transcription factors the phytochrome-interacting factor (PIF) family are derepressed. PIFs induce auxin production, which is required for promoting leaf hyponasty, thereby favoring access unfiltered sunlight. Abscisic acid (ABA) has also been implicated control with gene...
