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 ...
Acute effects of fine particulate air pollution on ST segment height: A longitudinal study
(2010)
Background
The mechanisms for the relationship between particulate air pollution and cardiac disease are not fully understood. Air pollution-induced myocardial ischemia is one of the potentially important mechanisms.

Ancient gene transfer from algae to animals: Mechanisms and evolutionary significance
(2012)
Background
Horizontal gene transfer (HGT) is traditionally considered to be rare in multicellular eukaryotes such as animals. Recently, many genes of miscellaneous algal origins were discovered in choanoflagellates. ...
Horizontal gene transfer of epigenetic machinery and evolution of parasitism in the malaria parasite Plasmodium falciparum and other apicomplexans
(2013)
Background
The acquisition of complex transcriptional regulatory abilities and epigenetic machinery facilitated the transition of the ancestor of apicomplexans from a free-living organism to an obligate parasite. The ...
Carl Woese, Dick Young, and the roots of astrobiology
(2014-03)
The beginning of the space age in the late 1950s gave rise to innovative and interdisciplinary research concepts and perspectives, including the concept of “exobiology” as a way to approach the fundamental aspects of biology ...
Genome Analysis of Planctomycetes Inhabiting Blades of the Red Alga
(2016-03)
Porphyra is a macrophytic red alga of the Bangiales that is important ecologically and economically. We describe the genomes of three bacteria in the phylum Planctomycetes (designated P1, P2 and P3) that were isolated from ...
Ordinal-Level Phylogenomics of the Arthropod Class Diplopoda (Millipedes) Based on an Analysis of 221 Nuclear Protein-Coding Loci Generated Using Next-Generation Sequence Analyses
(2013)
Background
The ancient and diverse, yet understudied arthropod class Diplopoda, the millipedes, has a muddled taxonomic history. Despite having a cosmopolitan distribution and a number of unique and interesting ...
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 ...
Genetic associations at 53 loci highlight cell types and biological pathways relevant for kidney function
(2016-01)
Reduced glomerular filtration rate defines chronic kidney disease and is associated with cardiovascular and all-cause mortality. We conducted a meta-analysis of genome-wide association studies for estimated glomerular ...
