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.

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 and phototropism are closely connected processes that allow plants to adjust their growth direction in response to directional light. Discover how phototropins, auxin transport, asymmetric auxin distribution, and differential cell expansion work together to control plant bending and directional growth.

Photoperiodism allows plants to use day length and the timing of light and darkness to regulate flowering. Discover how the circadian clock, phytochromes, cryptochromes, PIFs, plant hormones, CONSTANS, and FT coordinate photoperiodic flowering.

The plant circadian clock coordinates daily rhythms in growth, photosynthesis, metabolism, and development. Discover how phytochromes and other photoreceptors interact with the circadian clock, PIF transcription factors, plant hormones, temperature, and photoperiodic signals.
