Pseudomonas prosekii isolated in Antarctica inhibits plantpathogenic strains of Pseudomonas viridiflava and Pseudomonas fluorescens
Pseudomonas-caused plant diseases are present worldwide and affect most of the major lineages of higher plants which, as a consequence, may result in significant economic losses. Despite the use of bacteriocins produced by rhizosphere and soil bacteria has been nowadays considered as novel crop protection approach, antagonistic interactions of cold-adapted isolates toward agriculturally important phytopathogenic bacteria have not been studied yet. In this study, we tested inhibition activity of Antarctic Pseudomonas spp. against phytopathogenic pseudomonads. Four Antarctic stains (P. prosekii CCM 8878, CCM 8879, and CCM 8881 and Pseudomonas sp. CCM 8880) inhibited several phytopathogenic strains of P. viridiflava and P. fluorescens. Based on inhibition zone character and previous genome research we suggest that L-pyocin activity was responsible for this effect against P. viridiflava strains and that tailocin inhibited P. fluorescens isolate.
