AUX/IAA proteins are key transcriptional repressors in the auxin signaling pathway. Discover how TIR1 and AFB receptors promote AUX/IAA degradation, release ARF transcription factors, and regulate gene expression involved in roots, shoots, organ formation, phototropism, and plant development.

Auxin receptors allow plant cells to perceive the growth hormone auxin and translate hormone levels into developmental responses. Discover how TIR1 and AFB proteins, SCF ubiquitin ligases, AUX/IAA degradation, and ARF transcription factors regulate plant growth, root development, phototropism, organ formation, and environmental responses.

Auxin signaling allows plant cells to translate hormone concentration into changes in gene expression, growth, and development. Discover how TIR1/AFB receptors, AUX/IAA proteins, ARF transcription factors, and hormone crosstalk regulate roots, shoots, phototropism, organ formation, and plant architecture.
