What We Know

 * In high intensity light, wild type cyanobacteria downregulate Photosystem I muramatsu.
 * The mutant pmgA cannot downregulate Photosystem I in high intensity light muramatsu.
 * pmgA mutants initially grow well in high intensity light (better than wild type) but after 48 hours they succumb to oxidative stress muramatsu.

What We Don't Know (but need to know)

 * What are the bottlenecks in transfering energy through (and between) the photosystems?
 * How is oxidative stress created from exposure to high intensity light?
 * What are natural methods of controlling oxidative stress?
