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.

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 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.

A scientific plant-signaling illustration showing a phytochrome receiving red and far-red light, interacting with PIF transcription factors, and connecting to auxin, gibberellin, and brassinosteroid pathways that regulate plant growth.

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.
