| Summary: | The CO2 content of Earth's atmosphere is rapidly increasing due to human consumption of fossil fuels. Models based on short-term culture experiments predict that major changes will occur in marine phytoplankton communities in the future ocean, but these models rarely consider how the evolutionary potential of phytoplankton or interactions within marine microbial communities may influence these changes. Here we experimentally evolved representatives of four phytoplankton functional types (silicifiers, calcifiers, coastal cyanobacteria, and oligotrophic cyanobacteria) in co-culture with a heterotrophic bacterium, Alteromonas, under either present-day or predicted future pCO2 conditions. The data and analysis code in this dataset show that the genomes of all four phytoplankton as well as Alteromonas evolved over the course of the experiment. Mutations in oxidative stress related genes (PTOX and thioredoxin reductase) were ubiquitous in evolved cultures of Prochlorococcus, suggesting adaptation in response to ... |
