Members of the Roseobacter clade are equipped with a tremendous diversity of metabolic
capabilities, which in part explains their success in so many different marine habitats. Ideas …

The frequencies of alternative synonymous codons vary both among species and among
genes from the same genome. These patterns have been inferred to reflect the action of …

Understanding of the phylogeny and interrelationships of the genera within the order
'Enterobacteriales' has proven difficult using the 16S rRNA gene and other single-gene or …

The phylogeny of the large bacterial class Gammaproteobacteria has been difficult to
resolve. Here we apply a telescoping multiprotein approach to the problem for 104 diverse …

The genetic code relates nucleotide sequence to amino acid sequence and is shared across
all organisms, with the rare exceptions of lineages in which one or a few codons have …

▪ Abstract The continuous flow of genomic data is creating unprecedented opportunities for
the reconstruction of molecular phylogenies. Access to whole-genome data means that …

The origin, evolution, and functional relevance of genomic variations in GC content are a
long-debated topic, especially in mammals. Most of the existing literature, however, has …

So far, most methods for identifying sequences under selection based on comparative
sequence data have either assumed selectional pressures are the same across all branches …

Abstract Background The genus Arsenophonus is a group of symbiotic, mainly insect-
associated bacteria with rapidly increasing number of records. It is known from a broad …

Obligate endocellular symbiotic bacteria of insects and other organisms generally exhibit
drastic genome reduction. Recently, it was shown that symbiotic gut bacteria of some …
