The Flaviviridae family of positive-sense single-stranded RNA (+ssRNA) viruses includes viral taxa which greatly impact public health worldwide. To explore how the viruses within the Flaviviridae family evolve, we examined the extent to which these viral taxa use nucleotide covariance, spontaneous mutation, and/or homologous recombination to vary their genotype as well as the resulting phenotype. We developed and used CovarView to assist us in simultaneously viewing and inspecting the results from whole genome covariance analyses. This resulted in the identification of previously-characterized RNA functional structures in the genomes of hepatitis C virus (HCV), as well as a new RNA functional …
Poxvirus Evolution: The Role Of Horizontal Gene Transfer, Mary Rebecca Odom
Poxvirus Evolution: The Role Of Horizontal Gene Transfer, Mary Rebecca Odom
All ETDs from UAB
We have investigated the set of all poxvirus proteins for information about the origins of protein coding genes of the Poxviridae family of viruses. A global assessment of all poxvirus proteins for levels of similarity to proteins of other organisms, including eukaryotes, viruses, and prokaryotes, has suggested trends and relationships informative about poxvirus evolution and poxvirus interactions with hosts. Our research has focused on the poxvirus proteins subset this assessment identified as likely to have evolutionary histories involving horizontal gene transfer (HGT). We have used phylogenetic reconstructions to individually determine the sources of more than 70 horizontally transferred genes present …
