Trichoderma/pathogen interactions: measurement of antagonistic chemicals produced at the antagonist/pathogen interface using a tubular bioassay
Letters in Applied Microbiology 27 (5), 283-286
Abstract: A tubular bioassay was used to measure analytically the local production and concentration of the antifungal Trichoderma secondary metabolite 6-n-pentyl-2H-pyran-2-one (6PAP) at the Trichoderma antagonist/pathogen interface. 6PAP levels significantly increased in the presence of the pathogen Botrytis cinerea, typically 300-700%, and were highest near the pathogen source. The level of response for a particular Trichoderma isolate was found to vary with the test organism used. Two products produced by biotransformation of 6PAP by B. cinerea in response to the interaction were also detected.
