A series of novel aromatic carboxylic acid amides were synthesized and tested for their activities against six phytopathogenic fungi by an in vitro mycelia growth inhibition assay. Most of them displayed moderate to good activity. Among them N-(2-(1H-indazol-1-yl)phenyl)-2-(trifluoromethyl)benzamide (3c) exhibited the highest antifungal activity against Pythium aphanidermatum (EC50 = 16.75 µg/m...

An improved protocol for the isolation of high-quality DNA from fungi is described. The method involves inactivating proteins by SDS/proteinase K and precipitating polysaccharides in the presence of high salt. Further purification is based on differential solubility of DNA and high molecular weight polysaccharides in aqueous media. The procedure does not use the toxic and potentially hazardous ...
