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 ...
Analyses of the oligopeptide transporter gene family in poplar and grape
(2011)
Background
Oligopeptide transporters (OPTs) are a group of membrane-localized proteins that have a broad range of substrate transport capabilities and that are thought to contribute to many biological processes. The OPT ...
Evidence for acquisition of virulence effectors in pathogenic chytrids
(2011)
Background
The decline in amphibian populations across the world is frequently linked to the infection of the chytrid fungus Batrachochytrium dendrobatidis (Bd). This is particularly perplexing because Bd was only recently ...
Algal genes in aplastidic eukaryotes are not necessarily derived from historical plastids
(2012-07)
In photosynthetic eukaryotes, many genes were transferred from plastids or algal endosymbionts to nuclear genomes of host cells. These transferred genes are often considered genetic footprints of plastids. However, genes ...
Transcriptome sequencing of Crucihimalaya himalaica (Brassicaceae) reveals how Arabidopsis close relative adapt to the Qinghai-Tibet Plateau
(2016-02)
The extreme environment of the Qinghai-Tibet Plateau (QTP) provides an ideal natural laboratory for studies on adaptive evolution. Few genome/transcriptome based studies have been conducted on how plants adapt to the ...
Genome-wide and molecular evolution analysis of the subtilase gene family in
(2014-12)
Background
Vitis vinifera (grape) is one of the most economically significant fruit crops in the world. The availability of the recently released grape genome sequence offers an opportunity to identify and analyze some ...
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 ...
The scale and evolutionary significance of horizontal gene transfer in the choanoflagellate
(2013-10)
Background
It is generally agreed that horizontal gene transfer (HGT) is common in phagotrophic protists. However, the overall scale of HGT and the cumulative impact of acquired genes on the evolution of these organisms ...
