PARSING POLYPHYLETIC PUERARIA : DELIMITING DISTINCT EVOLUTIONARY LINEAGES THROUGH PHYLOGENY
(East Carolina University, 2013)A taxon is defined as polyphyletic when it does not include the last common ancestor of all true members of the taxon, resulting in a number of subgroups not united by a common ancestor. Previous work has suggested Pueraria ... -
RNA polymerase II CTD Evolutionary Diversity and Associated Protein Identification in Green and Red Algae
(East Carolina University, 2014)In model eukaryotes, the C-terminal domain (CTD) of the largest subunit (RPB1) of DNA-dependent RNA polymerase II is composed of tandemly repeated heptads with the consensus sequence YSPTSPS. Both the core motif and tandem ... -
Transcriptional Analysis of the Bacteroides fragilis Starch Utilization Operon, osuA
(East Carolina University, 2011)The opportunistic pathogen Bacteroides fragilis is a symbiotic organism that inhabits the human gastrointestinal tract where it utilizes dietary and host-derived polysaccharides as carbon and energy sources. If abdominal ... -
USE OF GENETIC TECHNIQUES TO IDENTIFY THE DIET OF COWNOSE RAYS, RHINOPTERA BONASUS, IN NORTH CAROLINA AND VIRGINIA : AN ANALYSIS OF SHELLFISH PREY ITEMS
(East Carolina University, 2013)Cownose rays, Rhinoptera bonasus, are considered voracious predators on mollusks and have been implicated in the consumption of commercially important species of shellfish on the East Coast. Digestive tracts of the 32 ... -
Widespread impact of horizontal gene transfer on plant colonization of land
(2012-10)In complex multicellular eukaryotes such as animals and plants, horizontal gene transfer is commonly considered rare with very limited evolutionary significance. Here we show that horizontal gene transfer is a dynamic ...
