Members of the class Candidatus Ordosarchaeia imply an alternative evolutionary scenario from methanogens to haloarchaea

Abstract
Abstract The origin of methanogenesis can be traced to the common ancestor of non-DPANN archaea, whereas haloarchaea (or Halobacteria) are believed to have evolved from a methanogenic ancestor through multiple evolutionary events. However, due to the accelerated evolution and compositional bias of proteins adapting to hypersaline habitats, Halobacteria exhibit substantial evolutionary divergence from methanogens, and the identification of the closest methanogen (either Methanonatr

Tissue-associated and vertically transmitted bacterial symbiont in the coral Pocillopora acuta

Abstract
Abstract Coral microhabitats are colonized by a myriad of microorganisms, including diverse bacteria which are essential for host functioning and survival. However, the location, transmission, and functions of individual bacterial species living inside the coral tissues remain poorly studied. Here, we show that a previously undescribed bacterial symbiont of the coral Pocillopora acuta forms cell-associated microbial aggregates (CAMAs) within the mesenterial filaments. CAMAs were f

Flexible genomic island conservation across freshwater and marine Methylophilaceae

Abstract
Abstract The evolutionary trajectory of Methylophilaceae includes habitat transitions from freshwater sediments to freshwater and marine pelagial that resulted in genome reduction (genome-streamlining) of the pelagic taxa. However, the extent of genetic similarities in the genomic structure and microdiversity of the two genome-streamlined pelagic lineages (freshwater “Ca. Methylopumilus” and the marine OM43 lineage) has so far never been compared. Here, we analyzed complete genome

The best of both worlds: a proposal for further integration of Candidatus names into the International Code of Nomenclature of Prokaryotes

Abstract
The naming of prokaryotes is governed by the International Code of Nomenclature of Prokaryotes (ICNP) and partially by the International Code of Nomenclature for Algae, Fungi and Plants (ICN). Such codes must be able to determine names of taxa in a universal and unambiguous manner, thus serving as a common language across different fields and activities. This unity is undermined when a new code of nomenclature emerges that overlaps in scope with an established, time-tested code and uses the same

Spirochaete genome identified in red abalone sample represents a novel genus Candidatus Haliotispira gen. nov. within the order Spirochaetales

Names
Ca. Haliotispira Ca. Haliotispira prima
Abstract
A fully assembled spirochaete genome was identified as a contaminating scaffold in our red abalone (Haliotis rufescens) genome assembly. In this paper, we describe the analysis of this bacterial genome. The assembled spirochaete genome is 3.25 Mb in size with 48.5 mol% G+C content. The proteomes of 38 species were compared with the spirochaete genome and it was discovered to form an independent branch within the family Spirochaetaceae

Infection with ‘Candidatus Liberibacter asiaticus’ improves the fecundity of Diaphorina citri aiding its proliferation: A win‐win strategy

Citation

Names
Ca. Liberibacter asiaticus
Abstract
AbstractThe evolution of insect vector‐pathogen relationships has long been of interest in the field of molecular ecology. One system of special relevance, due to its economic impacts, is that between Diaphorina citri and ‘Candidatus Liberibacter asiaticus’ (CLas), the cause of the severe Asian form of huanglongbing. CLas‐positive D. citri are more fecund than their CLas‐negative counterparts, boosting opportunities for pathogens to acquire new vector hosts. The molecular mechanism behind this l

An update on the presence of Leucomigus candidatus candidatus (Coleoptera, Curculionidae, Lixinae) in Romania

Abstract
This survey presents the first precise records of Leucomigus candidatus candidatus (Pallas, 1781) in Romania, confirming thus the presence of this species almost a century after its first and single record. Furthermore, ecology, habitat preference and distribution are discussed. We illustrate this taxon with high quality macro photographs, including the male genitalia with the everted and inflated endophallus. Comparative plates with similar-looking species are provided. New localities from Roma
