Concerted gene recruitment in early plant evolution
(East Carolina University, 2008-07)
Background: Horizontal gene transfer occurs frequently in prokaryotes and unicellular eukaryotes. Anciently acquired genes, if retained among descendants, might significantly affect the long-term evolution of the recipient ...
Analyses of domains and domain fusions in human proto-oncogenes
(East Carolina University, 2009-03-17)
Background: Understanding the constituent domains of oncogenes, their origins and their fusions may shed new light about the initiation and the development of cancers. Results: We have developed a computational pipeline ...
Did an ancient chlamydial endosymbiosis facilitate the establishment of primary plastids?
(East Carolina University, 2007-06)
Background: Ancient endosymbioses are responsible for the origins of mitochondria and plastids, and they contribute to the divergence of several major eukaryotic groups. Although chlamydiae, a group of obligate intracellular ...
Are algal genes in nonphotosynthetic protists evidence of historical plastid endosymbioses?
(East Carolina University, 2009)
Background: How photosynthetic organelles, or plastids, were acquired by diverse eukaryotes is among the most hotly debated topics in broad scale eukaryotic evolution. The history of plastid endosymbioses commonly is ...
