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 ...
De Novo Transcriptome Assembly and Comparative Analysis Elucidate Complicated Mechanism Regulating Astragalus chrysochlorus Response to Selenium Stimuli
(2015-10)
Astragalus species are medicinal plants that are used in the world for years. Some Astragalus species are known for selenium accumulation and tolerance and one of them is Astragalus chrysochlorus, a secondary selenium ...
Drosophila Ctf4 is essential for efficient DNA replication and normal cell cycle progression
(2011)
Background
Proper coordination of the functions at the DNA replication fork is vital to the normal functioning of a cell. Specifically the precise coordination of helicase and polymerase activity is crucial for efficient ...
EGID: an ensemble algorithm for improved genomic island detection in genomic sequences
(2011)
Genomic islands (GIs) are genomic regions that are originally transferred from other organisms. The detection of genomic islands in genomes can lead to many applications in industrial, medical and environmental contexts. ...
Genome-Wide Meta-Analysis of Homocysteine and Methionine Metabolism Identifies Five One Carbon Metabolism Loci and a Novel Association of with Ischemic Stroke
(2014-03)
Circulating homocysteine levels (tHcy), a product of the folate one carbon metabolism pathway (FOCM) through the demethylation of methionine, are heritable and are associated with an increased risk of common diseases such ...
Habitat and Scale Shape the Demographic Fate of the Keystone Sea Urchin in Mediterranean Macrophyte Communities
(2012)
Demographic processes exert different degrees of control as individuals grow, and in species that span several habitats and spatial scales, this can influence our ability to predict their population at a particular ...
Nicotine exposure caused significant transgenerational heritable behavioral changes in Caenorhabditis elegans
(2013-09)
Passive and active exposure to tobacco smoking among youth is directly associated with immediate as well as long-term health deterioration. Despite all public health policies and efforts, the percentage of teenage smokers ...
Prey Responses to Predator Chemical Cues: Disentangling the Importance of the Number and Biomass of Prey Consumed
(2012)
To effectively balance investment in predator defenses versus other traits, organisms must accurately assess predation risk. Chemical cues caused by predation events are indicators of risk for prey in a wide variety of ...
Brain size varies with temperature in vertebrates
(2014-03)
The tremendous variation in brain size among vertebrates has long been thought to be related to differences in species’ metabolic rates. It is thought that species with higher metabolic rates can supply more energy to ...
