Published February 8 in the journal Nature Communications, the research team's portrait of the microscopic dinoflagellate Oxyrrhis marina reveals a predator so efficient that it has even acquired a gene from its prey.
"It's an interesting case of Lateral Gene Transfer, or the movement of genes between distantly related species," says Patrick Keeling, a UBC botany professor and one of the study's authors.
"Our study shows that Oxyrrhis marina has picked up a gene commonly used by marine bacteria for photosynthesis. Oxyrrhis probably got this gene by eating the bacteria, but the really interesting part is that the gene produces a protein called rhodopsin, which is a photoreceptor that can make energy from light."
