Mechanism of auxin-regulated gene expression in plants

Annu Rev Genet. 2009;43:265-85. doi: 10.1146/annurev-genet-102108-134148.


Plant hormones control most aspects of the plant life cycle by regulating genome expression. Expression of auxin-responsive genes involves interactions among auxin-responsive DNA sequence elements, transcription factors and trans-acting transcriptional repressors. Transcriptional output from these auxin signaling complexes is regulated by proteasome-mediated degradation that is triggered by interaction with auxin receptor-E3 ubiquitin ligases such SCF(TIR1). Auxin signaling components are conserved throughout land plant evolution and have proliferated and specialized to control specific developmental processes.
