ARF transcription factors translate auxin signals into changes in gene expression. Discover how ARFs interact with AUX/IAA proteins and regulate roots, shoots, organ formation, phototropism, branching, and plant development.

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 transport allows plants to control where growth occurs by establishing directional hormone flows through their tissues. Discover how PIN proteins, auxin gradients, and polar auxin transport regulate root development, shoot growth, organ formation, branching, phototropism, and plant architecture.

Phototropins are blue-light photoreceptors that help plants respond to the direction and intensity of light. Discover how phototropin signaling regulates phototropism, auxin distribution, stomatal opening, chloroplast movement, leaf positioning, and plant development.
