Talk:The Responses of Cyanobacteria to UV-B Irradiation

It is good that you devoted your page Cyanobacteria, a very deserving microorganism (what would we be without it). Your page had a good flow and the subtopics made the contents clear. It was good how you related the bacterium to the rest of the ecosystem and emphasized its importance.

Very nice! You used a clear and consistent writing style throughout the page that made it very easy to read. I really enjoyed the commentary that you made on each of the figures/pictures--this helped a lot in interpreting the data and leading us directly to the information of highest interest. From the Gliding section: would you be able to provide some background information on how the wavelength of light (i.e. UV or visible) relates to the ability of light to penetrate into soil? Does higher energy light always penetrate more into materials? I don't know much about the properties of light, but how is it that cyanobacteria in soil can move downward in the soil and absorb more visible light while avoiding UV light? Also, you presented a wide variety of techniques that cyanobacteria use to combat UV light, but is there any data that shows the effect on growth when these protective responses are upregulated? I can imagine that increasing production of MAA would require more energy and cause the growth rate to slow, but have any studies looked at growth rate with increasing amounts of exposure to UV light (and how that effects the amount of, say, MAA produced)? Your page provides insight into the way some of the most important microbes to this planet operate. Great job!
