Sunflecks and UVR8

Submitted by lgarneau on Fri, 04/19/2019 - 13:30

Sunflecks are transient patches of light that leak through openings in the canopy and interrupt shade. Sunflecks are ecophysiological and agricultural sources of energy for carbon gain. However, scientists have a very limited molecular understanding of how plant organs perceive and respond to sunflecks. In recent studies, the UVR8 photoreceptor has aided in advances toward an understanding of the physiology and molecular mechanisms behind sunflecks.



The paragraph lacks a "so what" aspect. Reading this paragraph, you think about the UVR8 photoreceptor and how it aids in undersanding the physiology and molecular mechanisms behind sunflecks, but so what? How does it work? Why has it been studied on recently?

What understandings of the physiology and mechanism behind sunflecks? Explain what recent findings have discovered.
