Complete Genome Sequences of Eleven Cluster DJ Gordonia rubripertincta Bacteriophages

TL;DR

This paper reports the complete genome sequences of 11 new phages that infect a specific soil bacterium, highlighting unique genetic features.

Contribution

The study provides new insights into the genomic diversity and unique characteristics of cluster DJ phages infecting Gordonia rubripertincta.

Findings

The phages have an average genome length of 60,185 bp and contain around 91 predicted genes.

Cluster DJ phages have a significantly lower G+C content (51.6%) compared to their host bacterium (~67%).

These phages exhibit unusual gene organization in lysis and include two related major tail protein genes.

Abstract

Eleven novel cluster DJ
Gordonia rubripertincta
phages were isolated from soil collected in Pittsburgh, PA and Omaha, NE. The genomes of these phages have an average length of 60,185 bp and contain an average of 91 predicted genes. Genes with putative roles in structure, assembly, lysis, and nucleic acid processing were identified. Cluster DJ phages have an unusually low average G+C content (51.6%) compared to
G. rubripertincta
(~67%). These phages are also unusual in the organization of genes involved in lysis, the inclusion of two related major tail protein genes, and the absence of a candidate tail assembly chaperone gene.
