Light stimulates growth of proteorhodopsin-containing marine Flavobacteria
Article Abstract:
An analysis of the complete genomes of three marine Flavobacteria, that cultivated bacteria in the phylum Bacteroidetes, shows that proteorhodopsin is present in one of the principal components of marine bacterioplankton. Thus phototropy conferred by proteorhodopsin is very crucial for providing critical amounts of energy, not only for respiration and maintenance but also for active growth of marine bacterioplankton in their natural environment.

Molecular diversity and ecology of microbial plankton
Article Abstract:
The history of microbial evolution in the oceans is very old but whether the microbial plankton populations harbor organisms that are models of adaptive sophistication remains to be seen. The present knowledge about marine bacterial and archaeal diversity is reviewed, as inferred from phylogenies of genes recovered from the ocean water column considering the implications of microbial diversity for understanding the ecology of the oceans.

Proteorhodopsin in the ubiquitous marine bacterium SAR11
Article Abstract:
SAR11 strain HTCC1062 ('Pelagibacter ubique') the first cultivated member of the extraordinarily abundant SAR11 clade, expresses a proteorhodopsin gene when cultured in autoclaved seawater and in its natural environment, the ocean. The Pelagibacter proteorhodopsin functions as a light-dependent proton pump.
