Predicting protein function with hierarchical phylogenetic profiles: The Gene3D phylo-tuner method applied to eukaryotic Genomes

, 2007
"Phylogenetic profiling'' is based on the hypothesis that during evolution functionally or physically interacting genes are likely to be inherited or eliminated in a codependent manner.

Reevaluation of the phylogenetic relationship between Mobilid and Sessilid peritrichs (Ciliophora, Oligohymenophorea) based on small subunit rRNA genes sequences [PDF]

, 2006
Based on morphological characters, peritrich ciliates (Class Olygohymenophorea, Subclass Peritrichia) have been subdivided into the Orders Sessilida and Mobilida.

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

Advanced Science, EarlyView.
This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...

Complete mitochondrial genome and phylogenetic analysis of Bombyx mandarina (Lepidoptera: Bombycidae)

Mitochondrial DNA. Part B. Resources, 2019
Bombyx mandarina is generally thought to be the wild ancestor nearest to the domesticated silkworm, B. mori. Here, we sequenced and assembled a complete mitochondrial genome (mitogenome) of B. mandarina.

Phylogenetic and developmental studies into the evolution of an insect novelty [PDF]

, 2008
The insects possess one of the most instantly recognisable bodyplans. This thesis addresses the evolution of one characteristic feature of the insects: the intercalary segment of the head.

Comparative Oligo‐FISH Mapping Illuminates Chromosomal Evolution Among Rutaceae Species Diverged Over 50 Million Years

Advanced Science, EarlyView.
Oligonucleotide‐based fluorescence in situ hybridization probes were developed in the model citrus species Citrus maxima. These probes were applied to comparative karyotyping across 14 species in the Rutaceae family. This analysis revealed chromosomal evolution in lineages that diverged from Citrus nearly 52 million years ago.

The complete mitochondrial genome of Unkanodes sapporonus (Hemiptera: Delphacidae)

Mitochondrial DNA. Part B. Resources, 2019
In this study, we sequenced and analyzed the complete mitochondrial genome of Unkanodes sapporonus (Matsumura) (Hemiptera: Delphacidae). The mitogenome was 17,765 bp in length with A + T content of 75.87%, containing 13 protein-coding genes, 22 tRNA ...

Phylogenetic relationships in Betula (Betulaceae) based on AFLP markers

, 2008
The genus Betula comprises various species in boreal and temperate climate zones of the Northern Hemisphere. The taxonomy of Betula is controversial and complicated by parallel evolution of morphological traits, polyploidization events, and extensive ...

Fluoroquinolone-resistant Escherichia coli, Indonesia [PDF]

, 2005
In a recent, population-based survey of 3,996 persons in Indonesia, fluoroquinolone (FQ)-resistant Escherichia coli was prevalent in the fecal flora of 6% of patients at hospital admission and 23% of patients at discharge, but not among healthy ...

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

Advanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...
