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 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.

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.

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.

Phototropism allows plants to adjust their growth direction in response to directional light. Discover how phototropins detect blue light and regulate auxin distribution, differential cell expansion, and plant growth toward or away from light.

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.

Cryptochromes are blue-light photoreceptors that help plants regulate growth, photomorphogenesis, flowering, circadian rhythms, and environmental responses. Discover how cryptochrome signaling interacts with phytochromes, PIFs, hormones, and the plant circadian clock.

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.

Phytochromes help plants interpret red and far-red light and regulate the transition from vegetative growth to flowering. Discover how phytochrome signaling interacts with PIF transcription factors, photoperiodism, plant hormones, temperature, and the circadian clock to control flowering time.
