Genome of Pectobacterium atrosepticum PB72 and Genome its Specific Bacteriophage PP90

What is it about?

We present the draft genome sequence of Pectobacterium atrosepticum strain PB72 infecting potatoes in Russia. PB72 is similar to the previously reported strain 21A. Considering potential biocontrol of this pathogen, an infectious bacteriophage was isolated and characterized. Phage vB_PatP_PP90 is a lytic podovirus of narrow host range belonging to the KP34virus genus.

Why is it important?

Pectobacterium atrosepticum is a plant pathogen associated with blackleg disease of potatoes, with sequenced strain SCRI1043 used as a model. P. atrosepticum is rated among the most destructive plant pathogens in Russia, and bacteriophage application is used as a biocontrol method. Both P. atrosepticum strain PB72 and phage PP90 were isolated from diseased potatoes in the Moscow Region of Russia in 2014.

To date, all characterized P. atrosepticum bacteriophages were isolated using strain SCRI1043 or uncharacterized strains. Hence, this work is a first report of the phage infecting a 21A-group strain that is genetically diverse from SCRI1043.
