Phytotoxic chaetoglobosins are produced by the plant pathogen Calonectria morganii (anamorph Cylindrocladium scoparium).
By the application of a bioassay based on cresson seedlings, two phytotoxic compounds were isolated by thin-layer chromatography from the culture fluid of a Calonectria morganii isolate. The structure of both compounds was elucidated by ESI/MS and NMR spectroscopy. According to the Chemical Abstracts database, they were identified as chaetoglobosin A and 19-O-acetylchaetoglobosin A, mycotoxins originally described for Chaetomium globosum.
