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.
