Article Abstract
The Coccolithoviridae is a recently discovered family of giant algal viruses. Here, we review the genomic and transcriptomic characterization of this family based on the results generated from a coccolithovirus microarray. The microarray has been used to aid the annotation of the genome, to investigate the infection process at the transcriptional level and to assess the diversity in genomic content within the family.

Lytic viruses have been implicated in the massive cellular lysis observed during algal blooms, through which they assume a prominent role in oceanic carbon and nutrient flows. Despite their impact on biogeochemical cycling, the transcriptional dynamics of these important oceanic events is still poorly understood. Here, we employ an oligonucleotide microarray to monitor host (Emiliania huxleyi) and virus (coccolithovirus) transcriptomic features during the course of E.

The diversity among the coccolithovirus strains held in the Plymouth Virus Collection (PVC) was assessed using three complementary techniques: phylogeny based on DNA polymerase and major capsid protein gene sequence; host range; and a new, microarray-based genome-wide approach. The PVC is composed of three groups of strains that are geographically and temporally distinct. Virus strains clustered according to these groups in all three diversity assessments.

The genus Coccolithovirus is a recently discovered group of viruses that infect the globally important marine calcifying microalga Emiliania huxleyi. Among the 472 predicted genes of the 407,339-base pair genome are a variety of unexpected genes, most notably those involved in biosynthesis of ceramide, a sphingolipid known to induce apoptosis. Uniquely for algal viruses, it also contains six RNA polymerase subunits and a novel promoter, suggesting this virus encodes its own transcription machinery.
