“…In HRPV-3 genome, they are preceded by a specific motif GCCCA. Localized single-strand interruptions have been identified before in the tailed ‘phiKMV-like viruses’ of Pseudomonas aeruginosa (53,54) and T5 (55–57). In those viruses, the discontinuities were shown to be nicks that were located in one strand only, and in phage φkF77, they were shown to be located in intergenic regions (54).…”

Archaeal viruses have been the subject of recent interest due to the diversity discovered in their virion architectures. Recently, a new group of haloarchaeal pleomorphic viruses has been discovered. It is distinctive in terms of the virion morphology and different genome types (ssDNA/dsDNA) harboured by rather closely related representatives. To date there are seven isolated viruses belonging to this group. Most of these share a cluster of five conserved genes, two of which encode major structural proteins. Putative proviruses and proviral remnants containing homologues of the conserved gene cluster were also identified suggesting a long-standing relationship of these viruses with their hosts. Comparative genomic analysis revealed three different ways of the genome organization, which possibly reflect different replication strategies employed by these viruses. The dsDNA genomes of two of these viruses were shown to contain single-strand interruptions. Further studies on one of the genomes suggested that the interruptions are located along the genome in a sequence-specific manner and exhibit polarity in distribution.

“…The genus was extended with other Pseudomonas phages (PT2, PT5, phikF77, and LUZ19) (30,31,32), Vibrio phage VP93 (5), and Ralstonia phage RSB1 (25). Recently, Pseudomonas fluorescens phage phi-2 has been proposed as a member of this genus (46).…”

“…This recently established phage genus is classified within the Autographivirinae subfamily of the Podoviridae along with the "T7-like viruses" and "SP6-like viruses." It groups phages with a common transcriptional scheme, able to infect a wide range of environmentally important bacteria, such as Vibrio spp., Pseudomonas spp., and Ralstonia solanacearum (5,8,25,30,31,32,33,46).…”

Pantoea agglomerans is a common soil bacterium used in the biocontrol of fungi and bacteria but is also an opportunistic human pathogen. It has been described extensively in this context, but knowledge of bacteriophages infecting this species is limited. Bacteriophages LIMEzero and LIMElight of P. agglomerans are lytic phages, isolated from soil samples, belonging to the Podoviridae and are the first Pantoea phages of this family to be described. The double-stranded DNA ( Pantoea agglomerans bacteria are Gram-negative, nonsporulating, facultatively anaerobic rods that belong to the family of the Enterobacteriaceae. Synonyms of this species name are Enterobacter agglomerans, Erwinia herbicola, and Erwinia milletiae (6, 19). The genus name Pantoea is derived from the Greek word pantoios, which means "of all sorts and sources," a descriptor well reflected in the habitat, since species of the genus have been isolated from plant surfaces, seeds, water, soil, and even humans and animals (3,19,41). Pantoea agglomerans is known in plant production as a biocontrol agent. It is used in postharvest control of a number of fungi (for instance, Penicillium expansum, Rhizopus stolonifer, Monilinia laxa, and Botrytis cinerea) on a wide variety of fruits (18,44,45,54).

“…Canonical nicks were first discovered in T5 and in its close relative bacteriophage BF23 in the 1960s, and this feature was considered to be unique for these phages for a long time [12], [13], [14]. Later, P. aeruginosa phiKMV-like phages were also found to contain single-chain interruptions in their DNA [36], [15].…”

The complete sequence of the 46,267 bp genome of the lytic bacteriophage tf specific to Pseudomonas putida PpG1 has been determined. The phage genome has two sets of convergently transcribed genes and 186 bp long direct terminal repeats. The overall genomic architecture of the tf phage is similar to that of the previously described Pseudomonas aeruginosa phages PaP3, LUZ24 and phiMR299-2, and 39 out of the 72 products of predicted tf open reading frames have orthologs in these phages. Accordingly, tf was classified as belonging to the LUZ24-like bacteriophage group. However, taking into account very low homology levels between tf DNA and that of the other phages, tf should be considered as an evolutionary divergent member of the group. Two distinguishing features not reported for other members of the group were found in the tf genome. Firstly, a unique end structure – a blunt right end and a 4-nucleotide 3′-protruding left end – was observed. Secondly, 14 single-chain interruptions (nicks) were found in the top strand of the tf DNA. All nicks were mapped within a consensus sequence 5′-TACT/RTGMC-3′. Two nicks were analyzed in detail and were shown to be present in more than 90% of the phage population. Although localized nicks were previously found only in the DNA of T5-like and phiKMV-like phages, it seems increasingly likely that this enigmatic structural feature is common to various other bacteriophages.
