A Place in the Sun: LED arrays that mimic natural spectral transitions


Experimental protocols for growth of plants typically use square-wave white light regimes which do not reflect the natural diurnal light patterns. Our aim is to build an LED lighting array system and write software that can enable researchers to explore a range of physiological responses under more natural dawn and dusk lighting transitions. We plan to use this equipment to compare the phase and amplitude of clock gene expression (via expression luciferase image analysis) of plants grown under our simulated natural lighting conditions and a standard square wave light regime
