A virulent strain of Diaporthe gulyae, isolated from stem cankers of sunflower and known to be pathogenic to saffron thistle, has been shown to produce both known and previously undescribed metabolites when grown in either static liquid culture or a bioreactor. Together with phomentrioloxin, a phytotoxic geranylcyclohexenetriol recently isolated from a strain of Phomopsis sp., two new phytotoxic trisubstituted α-pyrones, named gulypyrones A and B (1 and 2), and two new 1,O- and 2,O-dehydro…

Chemical components from the seeds of: Catalpa bungei and their inhibitions of soluble epoxide hydrolase, cholinesterase and nuclear factor kappa B activities
TLDR
Two new chlorinated iridoids, named bungosides A and B, were isolated from the seeds of Catalpa bungei and elucidated on the basis of NMR analysis, including the assignment of the absolute configuration by employing electronic circular dichroism (CD) and time-dependent density functional theory (TDDFT) calculations.
Structure and Absolute Configuration of Kongiidiazadione, a New Phytotoxic 3-Substituted-5-Diazenylcyclopentendione Produced by Diaporthe Kongii.
TLDR
Kongiidiazadione proved to have a weak antibacterial activity against gram-positive Bacillus amyloliquefaciens, and had a differential impact, causing clear necrosis, in particular to Helianthus annuus.
Phytotoxic Lipophilic Metabolites Produced by Grapevine Strains of Lasiodiplodia Species in Brazil.
TLDR
Phytotoxic metabolites produced in liquid culture by six species of Lasiodiplodia isolated in Brazil and causing Botryosphaeria dieback of grapevine were chemically identified and related to the symptoms these pathogens cause in the grapevine host plants are discussed.
A tale of four kingdoms - isoxazolin-5-one- and 3-nitropropanoic acid-derived natural products.
TLDR
This review reports on natural compounds that derive from the isoxazolinone ring as well as the 3-nitropropanoic acid (3-NPA) moiety, which are found in compounds that have been identified in plants, insects, bacteria and fungi.

Phomentrioloxin, a fungal phytotoxin with potential herbicidal activity, and its derivatives: a structure-activity relationship study.
TLDR
Seven derivatives obtained by chemical modifications of the toxin were assayed for phytotoxic, antimicrobial, and zootoxic activities, and the structure-activity relationships were examined, providing insights into an investigation of the structural requirements for activity.
Production of phytotoxins by Phoma exigua var. exigua, a potential mycoherbicide against perennial thistles.
TLDR
It was demonstrated that the above two strains, grown in liquid and solid cultures, produced p-hydroxybenzaldehyde, cytochalasins B, F, Z2 and Z3, and deoxaphomin, which demonstrated the highest level of toxicity on leaves of S. arvensis.
Agropyrenol, a phytotoxic fungal metabolite, and its derivatives: a structure-activity relationship study.
TLDR
Both the double bond and the diol system of the 3,4-dihydroxypentenyl side chain as well as the aldehyde group at C-1 of the phenolic ring of agropyrenol proved to be important for the phytotoxicity and could be useful in devising new natural herbicides for practical application in agriculture.

Phytotoxic polyketides produced by Phomopsis foeniculi, a strain isolated from diseased Bulgarian fennel
TLDR
Using a bioassay-guided isolation and purification procedure, nectriapyrone and altersolanols A and J showed a modulated phytotoxicity, while macrosporin was not toxic and Altersolanol A was the most active compound.
Genetic characterization of a novel Phomopsis sp., a putative biocontrol agent for Carthamus lanatus
TLDR
Analysis of the selected isolates from saffron thistle with the nucleotide sequence of the partial ITS and tef1-α regions demonstrated that the sequences were distinct from all other species of Phomopsis so far described from crops in Australia.

TLDR
Several experiments described in this report argue against the selection theory for the attenuation of cultures of Helminthosporium sacchari, and some possible mechanisms for the activation of toxin biosynthesis are discussed.

Phomopsis spp. were isolated from plant and seed material of saffron thistle collected from several areas in New South Wales. Pathogenicity of these isolates was confirmed using a wound inoculation
