SOEST oceanographers part of $6 million grant to investigate aquatic viruses

Department of Oceanography faculty  Grieg Steward and Kyle Edwards are part of a multi-institutional team from four universities that received a $6 million grant to investigate how the information encoded in the genomes of viruses alters the properties of cells and influences the outcome of viral infections.

“A much more realistic accounting of the nuanced relationships between viruses and microbes is going to be needed if we want to fully understand how the Earth’s microbiome keeps our planet habitable” said Steward.

At UH-Manoa, Steward and Edwards will use their one-million-dollar portion of the grant to focus specifically on viruses infecting marine phytoplankton—microscopic organisms that conduct photosynthesis. Phytoplankton serve as the base of marine and freshwater food chains and produce more than half the oxygen on Earth. Viruses are a major source of mortality for phytoplankton and can dramatically alter how the food generated by photosynthesis is distributed in the marine food web.

To make the experimental work easier, one of the objectives of the multi-university collaboration is to develop and adapt microfluidics technology. Microfluidics will enable the scientists to examine—in a droplet of water smaller than mist—how a single virus and a single microbial cell interact. They aim to make new tools and resources in microfluids technology available to the broader scientific community.
