Molecular dynamics of Emiliania huxleyi and cooccurring viruses during two separate mesocosm studies.

ABSTRACT: In this study we used denaturing gradient gel electrophoresis, sequencing analysis, and analytical flow cytometry to monitor the dynamics and genetic richness of Emiliania huxleyi isolates and cooccurring viruses during two mesocosm experiments in a Norwegian fjord in 2000 and 2003. We exploited variations in a gene encoding a protein with calcium-binding motifs (GPA) and in the major capsid protein (MCP) gene to assess allelic and genotypic richness within E. huxleyi and E. huxleyi-specific viruses (EhVs), respectively. To our knowledge, this is the first report that shows the effectiveness of the GPA gene for analysis of natural communities of E. huxleyi. Our results revealed the existence of a genetically rich, yet stable E. huxleyi and EhV community in the fjordic environment. Incredib
