One of the distinctive features of mitochondria is that they have their own DNA. When compared to nuclear DNA, it is known that mitochondrial DNA (mtDNA) not only has a much higher rate of spontaneous mutation, but also arises from metabolically distinct precursor pools. Others from our laboratory have demonstrated...
Phagotrophic protists are major consumers of microbial biomass in aquatic ecosystems. However, biochemical mechanisms underlying prey recognition and phagocytosis by protists are not well understood. We investigated the potential roles of cell signaling mechanisms in chemosensory response to prey, and in capture of prey cells, by a marine ciliate (Uronema...
The Oregon Department of Education requires children to receive vision screening before entering elementary school, but does not require follow-up with an eye care professional after a failed screening. Whether such preventative vision care is effective at detecting children with vision problems was investigated through research from the American Optometric...
By identifying the relationships between abundance and metabolic activity in a bacterial community, we advance our knowledge of the marine carbon cycle. In the present study, our goal was to examine the role of protist grazing on the metabolic activity of γ- Proteobacteria in the upwelling system off the Oregon...
