Mycotoxin production by Alternaria alternata strains isolated from red delicious apples in Argentina.
Eleven Alternaria alternata strains isolated from Red Delicious apples in cold storage in Argentina, were tested for alternariol and alternariol methyl ether production in laboratory media and in whole fresh fruits. Most of them were able to produce both toxins in all media. They were detected also in mycelium free filtrates from liquid cultures and in asymptomatic tissues from inoculated fruit...
متن کاملCutaneous Phaeohyphomycosis Caused by Alternaria alternata Unresponsive to Itraconazole Treatment
Cutaneous alternariosis is an opportunistic infection that has been described mainly in patients treated with corticosteroids. We report a case of dermal alternariosis occurring in a woman treated with corticosteroids after a neurosurgery that was unresponsive to itraconazole. Treatment with intravenous voriconazole was initiated, followed by oral protocol, with marked improvement of the lesions.

Alternaria alternata transcription factor CmrA controls melanization and spore development.
Melanin is a black pigment widely distributed across the kingdoms, from bacterial to human. The filamentous fungus Alternaria alternata is a typical 'black fungus', which produces melanin in its hyphal and especially its asexual spore cell walls. Its biosynthesis follows the dihydroxynaphthalene (DHN) pathway with 1,8-DHN as an intermediate. Two genes, encoding a polyketide synthase (pksA) and ...
متن کاملMultiple phytohormone signalling pathways modulate susceptibility of tomato plants to Alternaria alternata f. sp. lycopersici
Three phytohormone molecules - ethylene (ET), jasmonic acid (JA) and salicylic acid (SA) - play key roles in mediating disease response to necrotrophic fungal pathogens. This study investigated the roles of the ET, JA, and SA pathways as well as their crosstalk during the interaction between tomato (Solanum lycopersicum) plants and a necrotrophic fungal pathogen Alternaria alternata f. sp. lyco...
