A New Retroposed Gene in Drosophila Heterochromatin Detected by Microarray-Based Comparative Genomic Hybridization
A genomic pattern of new gene origination is often dependent on a genomic method that can efficiently identify a statistically adequate number of recently originated genes. The heterochromatic regions have oft...

Open AccessLarge-scale analysis of transcriptional cis-regulatory modules reveals both common features and distinct subclasses
Transcriptional cis-regulatory modules (for example, enhancers) play a critical role in regulating gene expression. While many individual regulatory elements have been characterized, they have never been analyzed...

Eighteen novel polymorphic microsatellite loci developed from the Père David’s deer (Elaphurus davidianus)
Père David’s deer is a severely bottlenecked species but without showing inbreeding depression, making it essential to develop molecular markers to explore her genetic mechanism of population recovery. In this...

Development of twelve polymorphic microsatellite loci in polyploid endangered Omphalogramma vincaeflora Franch. (Primulaceae)
A total of twelve polymorphic microsatellite loci were developed from polyploid endangered species, Omphalogramma vincaeflora (Primulaceae). These loci were screened for variability among 45 individuals from thre...

The Complete Mitochondrial Genome Sequence of the Hornwort Megaceros aenigmaticus Shows a Mixed Mode of Conservative Yet Dynamic Evolution in Early Land Plant Mitochondrial Genomes
Land plants possess some of the most unusual mitochondrial genomes among eukaryotes. However, in early land plants these genomes resemble those of green and red algae or early eukaryotes. The question of when ...

Isolation and characterization of fifteen polymorphic microsatellite loci from Primula merrilliana (Primulaceae), an endemic from China
Primula merrilliana (Primulaceae) is an endangered plant endemic to south Anhui Province in China. In this study, we isolated fifteen polymorphic microsatellite loci from a population of ...

Multiple-scaled spatial genetic structures of Fraxinus mandshurica over a riparian–mountain landscape in Northeast China
Landscape genetics increasingly focuses on the way in which landscape features cause the fragmentation of lineages of terrestrial organisms. However, landscape features can also provide functional connectivity...

Open AccessRNA polymerase map** during stress responses reveals widespread nonproductive transcription in yeast
The use of genome-wide RNA abundance profiling by microarrays and deep sequencing has spurred a revolution in our understanding of transcriptional control. However, changes in mRNA abundance reflect the combin...

Eleven polymorphic microsatellite loci in Polygonatum filipes and cross-amplification in other congeneric species
Eleven polymorphic microsatellite loci were isolated from Polygonatum filipes, a plant endemic to China. The number of alleles per locus ranged from 3 to 7. The observed and expected heterozygosities ranged from ...

Isolation and characterization of twelve polymorphic microsatellite loci in Polygonatum cyrtonema and cross-species amplification
Twelve novel microsatellite loci were isolated in a perennial herb, Polygonatum cyrtonema. The polymorphism of each locus was analyzed by screening 23 individuals from a natural population. The number of alleles ...

PCR primers for microsatellite loci in a Madagascan waterbird, the Sakalava Rail (Amaurornis olivieri)
We isolated 76 microsatellite loci from the Sakalava rail (Amaurornis olivieri) genome. These were tested in 30 individuals from six sites (in three regions) across the species’ range in Madagascar. Thirty-four o...

Evolution of Enzymatic Activities of Testis-Specific Short-Chain Dehydrogenase/Reductase in Drosophila
The testis-specific gene **gwei (jgw) is a newly evolved short-chain dehydrogenase/reductase in Drosophila. Preliminary substrate screening indicated that JGW prefers long-chain primary alcohols as substrates, i...

Open AccessSelective Pressure to Increase Charge in Immunodominant Epitopes of the H3 Hemagglutinin Influenza Protein
The evolutionary speed and the consequent immune escape of H3N2 influenza A virus make it an interesting evolutionary system. Charged amino acid residues are often significant contributors to the free energy o...

Amino Acid Compositional Shifts During Streptophyte Transitions to Terrestrial Habitats
Across the streptophyte lineage, which includes charophycean algae and embryophytic plants, there have been at least four independent transitions to the terrestrial habitat. One of these involved the evolution...

Twenty-nine polymorphic microsatellite loci in Cyclura carinata, the Turks and Caicos Iguana, a critically endangered island endemic
Cyclura carinata, a critically endangered Caribbean rock iguana, now occupies less than 5% of its historic range. Remaining populations are genetically structured, but available tools are insufficient to identify...

Development and characterization of twelve polymorphic microsatellite loci for the Chinese concave-eared frog (Odorrana tormota)
The Chinese concave-eared frog is a rare species endemic to a restricted region of easternChina. In the present study, we isolated twelve polymorphic microsatellite loci from a dinucleotide—or trinucleotide—en...

Marker-assisted prediction of non-additive genetic values
It has become increasingly clear from systems biology arguments that interaction and non-linearity play an important role in genetic regulation of phenotypic variation for complex traits. Marker-assisted predi...
