Project Description

Prochlorococcus and its sister genus Synechococcus are the most abundant photosynthetic bacteria in the oceans, and play a central role in the global carbon cycle. Exchanges of fixed carbon and other nutrients between Prochlorococcus and marine heterotrophic bacteria, which rely on photosynthetically fixed carbon, form much of the base of the marine food web. We are interested in understanding the molecular mechanisms underlying the coexistence and ecosystem structure in the global oceans. This project aims to use bacterial genetics and experimental evolution of tractable cultures of Prochlorococcus and ubiquituos marine bacteria to determine the molecular bases of metabolic exchanges in the oceans.
