Characterization Of Phycoerythrin Physiology In Low-Light Adapted Prochlorococcus Ecotypes, Kathryn H. Roache-Johnson
Electronic Theses and Dissertations
The marine cyanobacteria Prochlorococcus and Synechococcus are the most abundant phototrophs in the oceans. They cohabit the oligotrophic ocean and thus have coevolved together, yet they have distinctly different methods for harvesting light. Synechococcus, like other cyanobacteria, possess phycobilisomes with various combinations of phycobiliproteins to capture wavelengths of light not otherwise available to chlorophyll. Prochlorococcus lack phycobilisomes and use divinyl chlorophyll b (Chl b2) as their primary accessory pigment to divinyl chlorophyll a (Chl a2) to capture light energy. In addition to the divinyl chlorophylls, Prochlorococcus has genes associated with the phycobiliprotein phycoerythrin (PE), the role of which is still …

Complete Genome Sequences And Phylogeny Of West Nile Virus Isolates From Southeastern United States, 2003-2012, Crystal Wedin
USF Tampa Graduate Theses and Dissertations
The study of the evolution and phylogeny of West Nile virus (WNV) has been an important area of research since the introduction of WNV in 1999. However, genome sequencing of isolates from the Southeastern part of the United States has been somewhat limited. To determine how WNV has evolved at a more localized level, ten isolates from Florida and Georgia from 2003-2012 were completely sequenced using Illumina's next-generation technology. In addition, a phylogenetic comparison of both the complete genome and select partial genomes was completed to ensure consistency among the results. This study further demonstrated the dominance of the North …
