Polyyne-producing Burkholderia suppress Globisporangium ultimum damping-off disease of Pisum sativum (pea).

ABSTRACT: Extensive crop losses are caused by oomycete and fungal damping-off diseases. Agriculture relies heavily on chemical pesticides to control disease, but due to safety concerns multiple agents have been withdrawn. Burkholderia were successfully used as commercial biopesticides because of their fungicidal activity and plant protective traits. However, their potential for opportunistic pathogenicity led to a moratorium on their registration as biopesticides. Subsequently, Burkholderia were shown to produce multiple specialised metabolites including potent antimicrobial polyynes. Cepacin A, a polyyne produced by Burkholderia ambifaria biopesticide strains was shown to be an important metabolite for the protection of germinating peas against Globisporangium ultimum (f
