In the past, bacterial phylogeny relied almost exclusively on 16S rRNA gene sequence
analysis. More recently, multilocus sequence analysis has been used to infer organismal …

The genus Agrobacterium was created a century ago by Conn who included it in the family
Rhizobiaceae together with the genus Rhizobium. Initially, the genus Agrobacterium …

Prokaryotic taxonomy is cyclically confronted with breakthroughs of methodological and
conceptual innovations. The “sexiest” novelties are often met by periods of reluctance but …

The ranks higher than the species in the prokaryotic taxonomy are primarily designated
based on phylogenetic analysis of the 16S rRNA gene sequences, but no definite standards …

We have followed with great interest the letters to Trends in Microbiology from Gribaldo and
Brochier-Armanet [1] and Garrity and Oren [2] concerning the need to improve the framework …

Bacteria account for a major proportion of Earth's biological diversity. They play essential
roles in quite diverse environments and there has been an increasing interest in bacterial …

Currently, the description of taxa designated Candidatus requires gene sequences and
