Frequency and diversity of Rhodopsins
How common are these genes, was it an isolated occurrence or are they globally distributed? Are rhodopsins only found in the SAR86 group (g-Proteobacteria) or are they found in diverse groups? Proteorhodopsin genes are distributed among divergent marine bacterial taxa. de la Torre et al PNAS. 100:

The previous data from Monterey Bay still only suggested the rhodopsins were in the Proteobacteria.
Sargasso Sea data set allowed the expansion of the taxa that contain rhodopsins
