Bilobetin and 4'''-O-methylamentoflavone were isolated and identified in the needles of Taxus baccata, for the first time in this species. The antifungal activity of biflavones from T. baccata and Ginkgo biloba, namely amentoflavone, 7-O-methylamentoflavone, bilobetin, ginkgetin, sciadopitysin and 2,3-dihydrosciadopitysin towards the fungi Alternaria alternata, Fusarium culmorum, Cladosporium o...

A series of 2-(N-arylsulfonylindol-3-yl)-3-aryl-1,3-thiazinan-4-one derivatives were synthesized and evaluated in vitro against seven phytopathogenic fungi, namely Fusarium graminearum, Alternaria solani, Fusarium oxysporium f. sp. vasinfectum, Alternaria brassicae, Valsa mali, Alternaria alternata, and Pyricularia oryzae. Among all derivatives, especially compound 4j exhibited a potential anti...

A new species is described, Xorides benxicus Sheng, sp. n., reared from the cerambycid twig-boring pest of Robinia pseudoacacia Linnaeus, Pterolophia alternata Gressitt, 1938, in Benxi County, Liaoning Province, China. A key is given to the species similar to Xorides benxicus Sheng, namely Xorides asiasius Sheng & Hilszczański, 2009, Xorides cinnabarius Sheng & Hilszczański, 2009 and Xorides sa...

Alternaria alternata spores are considered a well-known biological contaminant and a very common potent aeroallergen source that is found in environmental samples. The most intense exposure to A. alternata allergens is likely to occur outdoors; however, Alternaria and other allergenic fungi can colonize in indoor environments and thereby increase the fungal aeroallergen exposure levels. A conse...

Halotolerant and halophilic melanized fungi were recently described in hypersaline waters. A close study of the sterol composition of such fungi, namely Hortaea werneckii, Alternaria alternata, Cladosporium sphaerospermum, Cladosporium sp., and Aureobasidium pullulans revealed the dominance of ergosterol and the presence of 29 intermediates of its biosynthesis pathway. The presence or absence o...

Alternaria alternata were isolated and identified from root, foliage and soil of both wheat and rice crops and their aggressiveness was studied using aggressiveness analysis. Isolates of Alternaria alternata were genetically characterized using RAPD's. The investigations were based on surveys of wheat and rice crops in the rice-wheat cropping areas of Pakistan. The study showed that Alternaria ...
