Two Phytotoxins Isolated from the Pathogenic Fungus of the Invasive Weed Xanthium italicum
Chemistry and Biodiversity, 2020Alternariol and altenuisol were isolated as the major phytotoxins produced by an Alternaria sp. pathogenic fungus of the invasive weed Xanthium italicum. Altenuisol exhibited stronger phytotoxic effect compared with alternariol.

Experientia, 1975
Observations from preliminary experiments to discover the phytotoxicity, if any, of the fungal metabolite, citrinin, are presented. There seems to be a positive indication, warranting further investigation.

Annual Review of Microbiology, 1977
Representatives of all of the major genera of plant disease-causing bacteria have been shown to produce one or more phytotoxins. Toxicological studies on the bacterial diseases of the major food crops have not been extensive. Bacterial phytotoxins belong to a number of classes of organic substances, including peptide, derivatized amino acid ...

Phytotoxins as potential herbicides
Experientia, 1991Phytotoxins are produced in various culture media by many fungi that are pathogenic to weeds. These phytotoxins belong to a wide array of chemical substances including sesquiterpenoids, sesterterpenoids, diketopiperazines, peptides, spirocyclic lactams, isocoumarins, and polyketides.

Phytotoxins as molecular signals
1997It is customary to include under the name of phytotoxins those microbial metabolites that, with the exclusion of enzymes, damage plants at low concentrations. Many plant pathogenic bacteria and fungi produce phytotoxins in culture, but the potential role of these metabolites in pathogenesis has been seldom demonstrated.

Phytotoxins from the fungus Malbranchea aurantiaca
Phytochemistry, 2005Bioassay-directed fractionation of an ethyl acetate extract from cultures of the fungus Malbranchea aurantiaca led to the isolation of two phytotoxic compounds, namely, 1-hydroxy-2-oxoeremophil-1(10),7(11),8(9)-trien-12(8)-olide (1) and penicillic acid (2).

Publisher Summary The techniques used in this chapter are widely applicable to all bacterial phytotoxins, most intensively used to study toxins produced by Pseudomonus syringae. The phytotoxins produced by plant pathogenic bacteria are non-host specific and cause symptoms on many plants that cannot be infected by the toxin producing pathogen ...
