TL;DR: Good congruence was found between the discontinuous distribution of phenotypic properties and taxa delineated in the phylogenetic trees though diverse non-monophyletic taxa appeared to be based on the use of plesiomorphic character states as diagnostic features, underline the pitfalls inherent in phylogenies based upon single gene sequences.

TL;DR: A phylogenetic comparison of nitrogen fixation gene (nifH) is presented with the aim of elucidating the processes underlying the evolutionary history of this catalytic ability among actinobacteria.

TL;DR: Draft genomes of 40 Micromonospora type strains and two non-type strains are made available through the Genomic Encyclopedia of Bacteria and Archaea project and used to generate a phylogenomic tree which showed they could be assigned to well supported phyletic lines that were not evident in corresponding trees based on single and concatenated sequences of conserved genes.

TL;DR: Comparative genomics of the so far uncultured cluster-2 Candidatus Frankia datiscae Dg1 with cultivated Frankiae has revealed genome reduction, but no obvious physiological impairments, and a multi-gene phylogeny placed the two cluster-1 strains together at the root of the Frankia radiation.

TL;DR: The application of more advanced taxonomic and screening strategies showed that strains classified as novel species of Lentzea and Streptomyces synthesised new specialised metabolites thereby underpinning the premise that the extreme abiotic conditions in the Atacama Desert favour the development of a unique actinobacterial diversity which is the basis of novel chemistry.
