Sargasso Sea photoreceptor genes

From the IBEA press release 03/04/04:

One of the most important single discoveries from the Sargasso Sea environmental shotgun sequencing study is the 782 new rhodopsin-like photoreceptor genes. Only a few dozen photoreceptors have been characterized in microorganisms to date and less than 200 photoreceptors have been discovered from all species, including human where they are responsible for our vision. Therefore, this discovery represents a substantial increase in the total number of this family of proteins. One interpretation of this finding is that at least 50% of the new species discovered use some type of photobiology and could explain the diversity of species in such a low nutrient environment. Better understanding of these photoreceptor genes could be very important to IBEA researchers as they explore the mechanisms of photosynthesis as a means to efficiently and economically produce hydrogen as a fuel source.

They have DOE funding, thus the emphasis on potential fuel source applications, not that there's anything wrong with that. Who knows what Sorcerer II will find? Despite the hype, backing this expedition is tax dollars well spent, imo.
