“Clearly such a rise in genetic diversity may also have important phenotypic implications such as the emergence of viruses with altered antigenicity, virulence or tissue tropism.
“An envelope glycoprotein on the surface is thought to be responsible for mediating viral entry into cells, tissue tropism and host range.
“This protein is embedded in and extends exterior to the viral lipid membrane and is primarily responsible for host cell receptor binding and host cell tropism.
“It has a wide cell tropism and remains extra chromosomal, minimising the risk of insertional mutagenesis.
“Our data demonstrate that factors in addition to the amount of platelet rich plasma protein expressed determine the tropism of prions for certain tissues.
“The response of the heterotrophic bacterial community to iron addition was determined during the mesoscale iron enrichment experiment conducted in the eastern equatorial Pacific.
