Endophytic Burkholderia sp. SSG as a potential biofertilizer promoting boxwood growth.

ABSTRACT:

Background

Burkholderia sp. SSG is a bacterial endophyte isolated from boxwood leaves showing a resistant response to infection by the boxwood blight pathogen Calonectria pseudonaviculata. SSG acted as a protective and curative biocontrol agent for boxwood blight and as a bio-sanitizer of disease inoculum in the field. Many gene clusters involved in antibiotic production and plant growth promotion (PGP) were found in the genome, giving this endophyte great application potential as a treatment for plant protection. However, the PGP features have not been documented. This study investigated the plant growth promotion activity of SSG in boxwood.

Methods

To determine whether SSG is a plant growth promoting bacterium, four PGP traits, auxin and siderophore productio
