“…Deviations from this standard can be employed as potential evidence for HGT. Yavru has an average GC content of 64.3%, and Arthrobacter globiformis NRRL B-2979 has an average GC content of 66.2% (similar to those of published A. globiformis strains [ 21 ]). Gene 16 of Yavru, a MerR-like helix-turn-helix DNA binding domain protein, possesses a significantly higher GC content (73.1%) and therefore is a possible horizontal acquisition from a foreign genome.…”

We characterized the complete genome sequence of actinobacteriophage Yavru ( Siphoviridae ), a cluster FE bacteriophage infecting Arthrobacter globiformis NRRL B-2979; it was 89.5% identical to cluster FE phage Whytu, with a capsid width of 50 nm and a tail length of 90 nm. The genome was 15,193 bp in length, with 23 predicted protein-coding genes.

“…In addition, Arthrobacter pascens isolated from the rhizosphere of forest soil in China reported a salt-tolerant bacterial strain, that secretes IAA, dissolves inorganic phosphorus, and degrades persistent organic (POPs) pollutants like polycyclic aromatic hydrocarbons (PAHs) such as fluoranthene (30). Like that, Arthrobacter globiformis to which Pseudarthrobacter Hai'l2 is related was isolated from a cave deposit in India and contained biosynthetic genes for encoding putative secondary metabolites and other antibiotics and showed antimicrobial activity (31). Arthrobacter globiformis was also found to ameliorate salt stress, which suggests the possibility to use this strain as inoculum for plants growing in highly saline soils (32).…”

Worldwide biodiversity is impacted strikingly by global environmental change, and thus its impact is reflected in all life aspects. Identifying microorganisms in environmental samples, particularly soil could be a valuable interest to study their effect on soil quality and plant growth. Through this study, we conducted a molecular characterization of bacteria found in the rhizosphere of Medicago sativa plants grown in Hai'l soil and we highlighted their main properties. The analysis of sequences revealed that the main bacterial isolates were Pseudarthrobacter, Metabacillus, Priestia, and Massilia species. According to the sequence analyses and the phylogeny tree results, some of the identified bacteria were classified at the species level: one of the pseudarthrobacter isolates was identified clearly as Pseudarthrobacter phenanthrenivorans; Metabacillus isolates grouped with Metabacillus sediminilitoris and the two Priestia isolates closely related to Priestia aryabhattai. We concluded that Hai'l soil is a niche of diverse bacteria with a high interest in soil environment and ecosystems. Further studies are required for further classification of all identified bacteria and to define their specific role in the environment.

“…Typically, viral genes have about the same [ 30 ] or slightly lower GC content [ 31 ] compared to their bacterial hosts, suggesting that genes with higher GC content may have been horizontally transferred. BlueFeather had an overall average GC content of 64.30% and Arthrobacter globiformis mrc11 was found to have an overall GC content of 65.9% [ 32 ]. BlueFeather gene-specific average GC contents ranged from 59.30% to 70.30%, and genes with maximum average GC contents were considered for HGT.…”

BlueFeather, the singleton that wasn’t: Shared gene content analysis supports expansion of Arthrobacter phage Cluster FE

Bacteriophages (phages) exhibit high genetic diversity, and the mosaic nature of the shared genetic pool makes quantifying phage relatedness a shifting target. Early parameters for clustering of related Mycobacteria and Arthrobacter phage genomes relied on nucleotide identity thresholds but, more recently, clustering of Gordonia and Microbacterium phages has been performed according to shared gene content. Singleton phages lack the nucleotide identity and/or shared gene content required for clustering newly sequenced genomes with known phages. Whole genome metrics of novel Arthrobacter phage BlueFeather, originally designated a putative singleton, showed low nucleotide identity but high amino acid and gene content similarity with Arthrobacter phages originally assigned to Clusters FE and FI. Gene content similarity revealed that BlueFeather shared genes with these phages in excess of the parameter for clustering Gordonia and Microbacterium phages. Single gene analyses revealed evidence of horizontal gene transfer between BlueFeather and phages in unique clusters that infect a variety of bacterial hosts. Our findings highlight the advantage of using shared gene content to study seemingly genetically isolated phages and have resulted in the reclustering of BlueFeather, a putative singleton, as well as former Cluster FI phages, into a newly expanded Cluster FE.
