Engineered biosynthesis of thaxtomin phytotoxins
Critical Reviews in Biotechnology, 2020Herbicide-resistant weeds are a growing problem worldwide. Thaxtomin phytotoxins are a group of nitrated diketopiperazines produced by the potato common scab-causing pathogen Streptomyces scabies and other actinobacterial plant pathogens. They represent a unique class of microbial natural products with distinctive structural features and promising ...

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.

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.

Fungal phytotoxins as mediators of virulence
Current Opinion in Plant Biology, 2009Many phytopathogenic fungi exert their destructive effects by producing and secreting toxic low molecular weight compounds. In the past years a large number of novel fungal virulence factors and their modes of action have been identified. This review highlights effective phytotoxin-mediated strategies to distress, weaken or kill the plant host.

More chemistry of the thaxtomin phytotoxins
Phytochemistry, 2003Chemical and biochemical studies indicated the possible involvement of N-acetyltryptophan and 4-nitrotryptophan as intermediates in biosynthesis of the thaxtomin phytotoxins. A search for other potential pathways indirectly resulted in the identification of three unusual thaxtomin analogues derived from the o-thaxtomin A isomer.

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 ...

Symbiotic Cooperation in the Biosynthesis of a Phytotoxin
Angewandte Chemie International Edition, 2012Natural products play a key role in symbiotic interactions between microorganisms and higher organisms, covering all kingdoms of life. The function of these secondary metabolites may range from signaling compounds in mutualism to virulence factors and antibiotics in parasitic relationships.

Fungal Phytotoxins in Sustainable Weed Management
Current Medicinal Chemistry, 2018 Fungal phytotoxins are natural secondary metabolites produced by plant pathogenic fungi during host–pathogen interactions. They have received considerable particular attention for elucidating disease etiology, and consequently to design strategies for disease control.

Phytotoxins: Environmental Micropollutants of Concern?
Environmental Science & Technology, 2014Natural toxins such as mycotoxins or phytotoxins (bioactive compounds from fungi and plants, respectively) have been widely studied in food and feed, where they are stated to out-compete synthetic chemicals in their overall human and animal toxicological risk. A similar perception and awareness is yet largely missing for environmental safety.
