Epistasis not needed to explain low dN/dS [PDF]

open access: yesMcCandlish, D. M., Rajon, E., Shah, P., Ding, Y., & Plotkin, J. B. (2013). The role of epistasis in protein evolution. Nature, 497(7451), E1-E2, 2012
An important question in molecular evolution is whether an amino acid that occurs at a given position makes an independent contribution to fitness, or whether its effect depends on the state of other loci in the organism's genome, a phenomenon known as epistasis. In a recent letter to Nature, Breen et al. (2012) argued that epistasis must be "pervasive

Functional characterization of hexokinases in the moss Physcomitrella patens [PDF]

open access: yes, 2005
Carbohydrates are important nutrients and structural components in all living organisms. In plants they affect the developmental and metabolic processes throughout the plant life cycle.

Occurrence and integrated control of major rice diseases in China

open access: yesNew Plant Protection, EarlyView.
Rice is constantly under threat from a variety of pathogens. This review highlights the major diseases affecting rice in China, including three fungal diseases, two bacterial diseases, two viral diseases, and one nematode. The review also proposes future directions for an integrated approach to control these significant rice diseases.

Relation between Gene Content and Taxonomy in Chloroplasts [PDF]

open access: yesarXiv, 2016
The aim of this study is to investigate the relation that can be found between the phylogeny of a large set of complete chloroplast genomes, and the evolution of gene content inside these sequences. Core and pan genomes have been computed on \textit{de novo} annotation of these 845 genomes, the former being used for producing well-supported ...

Testing robustness of relative complexity measure method constructing robust phylogenetic trees for Galanthus L. Using the relative complexity measure [PDF]

open access: yes, 2013
Background: Most phylogeny analysis methods based on molecular sequences use multiple alignment where the quality of the alignment, which is dependent on the alignment parameters, determines the accuracy of the resulting trees.

Microbiota diversity and differences in the respiratory tract of children with pneumonia

open access: yesPediatric Investigation, EarlyView.
Differences in microbial communities in the upper and lower respiratory tract in patients with pneumonia were investigated in this study by sequencing the 16S rRNA genes in pharyngeal swabs and alveolar lavage fluid. Forty‐three subjects were enrolled in the study, and one upper and one lower respiratory tract sample were collected from each subject ...

The complete chloroplast genome sequences of two Chaenomeles species (Chaenomeles cathayensis and Chaenomeles thibetica)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete chloroplast genome sequence of Chaenomeles cathayensis and Chaenomeles thibetica was characterized from Illumina pair-end sequencing. The length of C. cathayensis and C.

Well-supported phylogenies using largest subsets of core-genes by discrete particle swarm optimization [PDF]

open access: yesarXiv, 2017
The number of complete chloroplastic genomes increases day after day, making it possible to rethink plants phylogeny at the biomolecular era. Given a set of close plants sharing in the order of one hundred of core chloroplastic genes, this article focuses on how to extract the largest subset of sequences in order to obtain the most supported species ...

Evolutionary relationships in Panicoid grasses based on plastome phylogenomics (Panicoideae; Poaceae) [PDF]

open access: yes, 2016
Background: Panicoideae are the second largest subfamily in Poaceae (grass family), with 212 genera and approximately 3316 species. Previous studies have begun to reveal relationships within the subfamily, but largely lack resolution and/or robust ...
