Complete genome sequence of the virus isolate vB_BthM-Goe5 infecting Bacillus thuringiensis.

Bacillus thuringiensis (Bt) is non-pathogenic for humans and serves as a biological control agent in agriculture. Understanding its phages will help to prevent industrial production loss of Bt products and will lead to a better understanding of phages in general. The complete genome of the new B. thuringiensis phage isolate vB_BthM-Goe5 (Goe5) was sequenced, revealing a linear 157,804-bp-long dsDNA chromosome flanked by 2579-bp-long terminal repeats. It contains two tRNAs and 272 protein coding regions, 69 of which could be assigned with an annotation. Morphological investigation, using transmission electron microscopy, revealed Myoviridae morphology. The formation of a double baseplate upon tail sheath contraction indicates a link to the group of SPO1-related phages. Comparative genomics with all Bacillus-related viral genomes available in the NCBI genome database during this investigation indicated that Goe5 was a unique isolate, with Bacillus phage Bastille as its closest relative.
