A series of linear furanocoumarins with different substituents have been designed and synthesized. Their structures were confirmed by ¹H-NMR spectroscopy, high resolution mass spectra (EI-MS), IR, and X-ray single-crystal diffraction. All of the target compounds were evaluated in vitro for their antifungal activity against Rhizoctorzia solani, Botrytis cinerea, Alternaria solani, Gibberella zea...

The bark beetle Scolytogenes birosimensis Niijima is suspected to be involved in the decline of Pittosporum tobira (Thunb. ex Murray) Aiton in the coastal areas of Japan. We isolated fungi from adult S. birosimensis in nine different localities in Japan to assess their potential association and predict their contribution to the success of the beetle. Results from morphological identification o...

Enzymes in culture filtrates of Rhizoctonia solani Kuhn grown using 4-day old or 20-day old bean (Phaseolus vulgaris L.) hypocotyl cell walls as a carbon source degraded xylan, galactan, galactomannan, araban, polygalacturonic acid, and carboxymethylcellulose. Extracts of lesions from R. solani infected plants, but not healthy plants, contained similar enzymatic activities. These enzyme sources...

Solanum tuberosum aspartic proteases (StAPs) with antimicrobial activity are induced after abiotic and biotic stress. In this study the ability of StAPs to produce a direct antimicrobial effect was investigated. Viability assays demonstrated that StAPs are able to kill spores of Fusarium solani and Phytophthora infestans in a dose-dependent manner. Localization experiments with FITC-labelled St...

Fusarium sp. has been shown to be a promising organism for enhanced production of xylanases. In the present study, xylanase production by 21 Fusarium sp. isolates (8 Fusarium culmorum, 4 Fusarium solani, 6 Fusarium verticillioides and 3 Fusarium equiseti) was evaluated under solid state fermentation (SSF). The fungal isolate Fusarium solani SYRN7 was the best xylanase producer among the tested ...

Antifungalmycin 702, a new polyene macrolide antibiotic produced by Streptomycespadanus JAU4234, has a broad antifungal activity and may have potential future agricultural and/or clinical applications. However, the mechanism of antifungal action of antifungalmycin 702 remains unknown. Antifungalmycin 702 strongly inhibited mycelial growth and sclerotia formation/germination of Rhizoctonia solan...

Dematiaceous fungi are darkly pigmented, filamentary moulds and are common in the environment as plant saprophytes and pathogens. Incidental reports of corneal ulcers that have been caused by species of this group have appeared in the literature, but the relative importance of this species as potential comeal pathogens has not been appreciated. As a group, second to Fusarium solani and other mo...

Herein, we report the first occurrence of web blight of rosemary caused by Rhizoctonia solani AG-1-IB in Gangneung, Gangwon Province, Korea, in August 2014. The leaf tissues of infected rosemary plants were blighted and white mycelial growth was seen on the stems. The fungus was isolated from diseased leaf tissue and cultured on potato dextrose agar for identification. The young hyphae had acut...

Half-root tests were established to examine the association between Heterodera glycines and the blue strain of Fusarium solani, the causal agent of sudden death syndrome (SDS) of soybean. Two independent root systems were established for soybean 'Coker 156' and inoculated (half root/half root) with F. solani, H. glycines, both organisms on opposite root halves, both organisms on one root half, ...
