Complete genome sequence of plant-pathogenic Pseudomonas sp. G2-4 from rhizosphere soil in Northern Greenland

Abstract

A novel bacterium, Pseudomonas sp. G2-4, was isolated from the rhizosphere soil of Oxyria digyna in Northern Greenland. This strain exhibited a notable ability to secrete strong extracellular proteases and was capable of developing brown spots on hot pepper leaves and soft rot on potatoes. The complete genome sequence of the phytopathogen G2-4 consisted of one circular chromosome with 6,651,895 bp (G + C content of 60.4%). Genomic analysis discovered 5,692 protein coding sequences (CDSs), among which one CDS was identified as a putative virulence factor responsible for encoding the extracellular protease. The extracellular proteolytic activity of G2-4 would at least partially contribute to the development of disease in the pepper and potato plants.
