Mitochondria are best known for their role in the generation of ATP by aerobic respiration.
Yet, research in the past half century has shown that they perform a much larger suite of …

Approximately 10% of bacterial genomes are split between two or more large DNA
fragments, a genome architecture referred to as a multipartite genome. This multipartite …

Viewed through the lens of the genome it contains, the mitochondrion is of unquestioned
bacterial ancestry, originating from within the bacterial phylum α-Proteobacteria …

The species is a fundamental unit of biological organization, but its relevance for Bacteria
and Archaea is still hotly debated. Even more controversial is whether the deeper branches …

The main objective of this work is the study of the phylogeny, evolution and ecological
importance of the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, the …

Host-adapted bacteria include mutualists and pathogens of animals, plants and insects.
Their study is therefore important for biotechnology, biodiversity and human health. The …

Diverse bacterial lineages form beneficial infections with eukaryotic hosts. The origins,
evolution, and breakdown of these mutualisms represent important evolutionary transitions …

Numerous studies have considered the emergence of metabolic pathways, but the modes of
recent evolution of metabolic networks are poorly understood. Here, we integrate …

Bacteria in the genus Brucella are important human and veterinary pathogens. The abortion
and infertility they cause in food animals produce economic hardships in areas where the …

Since their endosymbiotic origin, mitochondria have lost most of their genes. Although many
selective mechanisms underlying the evolution of mitochondrial genomes have been …
