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.

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.

Plant photoreceptors allow plants to sense different wavelengths of light and translate environmental information into developmental responses. Learn how phytochromes, cryptochromes, phototropins, and UVR8 regulate plant growth and development.

Photomorphogenesis is the process through which plants use light as a developmental signal. Discover how photoreceptors, hormones, gene expression, and light signaling regulate seedling development, chloroplast formation, growth, flowering, and plant architecture.
