Sensing and Signaling Networks in Plants. What’s Light Got to Do with It? Is the title of Dr. Tessa Pocock’s presentation March 15, 2017 at the Phosphor Global Summit to be held at the San Diego Marriott La Jolla. Recent advances in lighting technology are enabling the development of ‘designer’ crops. Light is the primary energy source required for crop growth and development but it also contains signals that shape the plant down to sub-cellular levels. The assessment of lighting and spectral distributions on photosynthesis, growth and phytochemical value will be presented.
