Relation of Polyphenol Oxidases to Fungitoxicity.
Stemphylium sarcinaeforme (Cav.) Wilt. (formerly Macrosporium sarcinaeforme Cav.) and Monilinia fructicola (Wint.) Honey (formerly Sclerotinia fructicola (Wint.) Rehm.) are two fungi which have been widely used as test organisms for screening fungicides in the laboratory. S. sarcinaeforme is resistant to the toxicity of phenolic and quinonoid compounds (herein referred to as phenols and quinone...
متن کاملBenzyl 3-(10-oxo-9,10-dihydrophenanthren-9-ylidene)dithiocarbazate
In the title compound, C(22)H(16)N(2)OS(2), the phenanthrene ring is nearly perpendicular to the phenyl ring, making a dihedral angle of 87.2 (2)°. Intra-molecular N-H⋯O inter-actions are present. In the crystal structure, the mol-ecules are linked through inter-molecular C-H⋯O inter-actions. The crystal structure is also stabilized by C-H⋯π inter-actions and weak π-π contacts [centroid-centroi...
متن کاملNovel fungitoxicity assays for inhibition of germination-associated adhesion of Botrytis cinerea and Puccinia recondita spores.
Botrytis cinerea and Puccinia recondita spores adhere strongly to polystyrene microtiter plates coincident with germination. We developed assays for inhibition of spore adhesion in 96-well microtiter plates by using sulforhodamine B staining to quantify the adherent spores. In both organisms, fungicides that inhibited germination strongly inhibited spore adhesion, with 50% effective concentrati...
متن کاملFungitoxicity against Botrytis cinerea of a Flavonoid Isolated from Pseudognaphalium robustum
The fungotoxicity against Botrytis cinerea of a flavonoid isolated from Pseudognaphalium robustum was analyzed. Two absorption column chromatographies and one semipreparative thin layer chromatography were used to purify the active flavonoid. It was determined, by H-NMR spectroscopy and co-elution with standards in HPLC, that this compound was 5,7-dihydroxy-3,8-dimethoxyflavone (gnaphaliin A). ...
متن کاملA nickel complex of a conjugated bis-dithiocarbazate Schiff base for the photocatalytic production of hydrogen.
We report a nickel complex containing a conjugated bis-dithiocarbazate ligand that is an active catalyst for the reduction of protons into hydrogen gas. Light-driven hydrogen generation is observed from a system containing this molecular nickel catalyst coupled with a fluorescein photosensitizer and triethylamine sacrificial donor. The photocatalytic system is stable for over 70 hours, achievin...
