Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere

nome fragments of these plankton, looking for specific gene sequences that would show how the plankton use sulfur compounds.

"This breakthrough in the microbial physiology of DMSP metabolism opens the door to understanding the biology and ecology of this globally important process," said William Whitman, a microbiologist at the University of Georgia and co-author of the Science paper. The discovery of a bacterial gene switch in these two groups of plankton will open new areas of research, since DMSP synthesis may account for almost all marine-created atmospheric sulfur. The findings also expand knowledge of how these marine organisms are involved in the routing of carbon and sulfur into the microbial food web.
