Auxin helps maintain root stem cells and organize the root stem-cell niche through spatial hormone gradients, PIN-mediated transport, TIR1/AFB signaling, WOX5, PLETHORA proteins, and hormone crosstalk.

Auxin is a central regulator of root meristem development, controlling stem-cell maintenance, cell division, differentiation, root growth, and root architecture through coordinated transport, signaling, and hormone interactions.

Auxin is a central regulator of lateral root formation. Discover how auxin transport, PIN proteins, pericycle cells, TIR1/AFB receptors, AUX/IAA proteins, ARF transcription factors, and hormone crosstalk control root branching and development.

Auxin is a central regulator of root development, controlling root growth, meristem activity, lateral root formation, gravitropism, root architecture, and responses to environmental conditions through coordinated transport and signaling.

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.

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.

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.
