Light spectral composition influences plant morphology, physiology, and development by impacting on processes ranging from photosynthesis to secondary metabolism.
Signaling pathways underlying growth and defense are linked, and light spectral composition therefore influences both processes.
Light spectral composition influences the behavior of plant-feeding arthropods and their carnivorous enemies directly or via changes in plant morphology and physiology.
Specific manipulation of light spectral composition in greenhouses through LEDs may optimize both crop production and crop protection, thus improving crop resilience.
