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 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 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.

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.

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.

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.

Phytochromes help seeds interpret red and far-red light and regulate the transition from dormancy to germination. Discover how phytochrome signaling interacts with PIF1, abscisic acid, gibberellins, temperature, and environmental conditions to control seed germination.

Phytochromes are light-sensitive proteins that allow plants to detect red and far-red light through reversible photoconversion between Pr and Pfr states. Learn how phytochrome structure, PIF interactions, and light signaling regulate plant growth, germination, shade avoidance, flowering, and development.

The red-to-far-red ratio is an important light signal that helps plants detect neighboring vegetation. Discover how phytochromes and PIF transcription factors translate changes in red and far-red light into changes in growth, shade avoidance, germination, flowering, and plant development.

Shade avoidance is a light-regulated plant response triggered by changes in red and far-red light caused by neighboring vegetation. Discover how phytochromes, PIF transcription factors, plant hormones, and other signaling pathways regulate elongation, branching, flowering, and plant architecture.

PIF transcription factors are key regulators of light-dependent plant development. Learn how PIFs interact with phytochromes, plant hormones, and other signaling pathways to control seedling growth, photomorphogenesis, shade avoidance, seed germination, and plant responses to changing environmental conditions.

Phytochromes are plant photoreceptors that detect red and far-red light and regulate major developmental processes. Explore how phytochrome signaling controls seed germination, seedling development, shade avoidance, flowering, plant architecture, and light-responsive gene expression.
