Alternaria spp. from sect. Alternaria are frequently associated with hypersensitivity pneumonitis, asthma and allergic fungal rhinitis and sinusitis. Since Alternaria is omnipresent in the outdoor environment, it is thought that the indoor spore concentration is mainly influenced by the outdoor spore concentration. However, few studies have investigated indoor Alternaria isolates, or attempted ...

Some common decay organisms of vegetables and ripened fruits are Alternaria species. Even fruits and vegetables kept under refrigeration can be spoiled by Alternaria species because the mold grows at low temperatures. Alternaria alternata is commonly found in grain in areas with a high incidence of esophageal cancer. Three metabolites, altertoxins I, II, and III, have been isolated from A. alte...

Trichoderma asperellum is one of the plant growth-promoting fungi (PGPF) presently marketed as biopesticide, biofertilizer and in soil amendments, due to its ability protect plants, enhance vegetative growth reduce pathogen populations. Keeping this view, here, we assessed efficacy against pathogens medicinal plants vitro field conditions Leaf spot disease Green leaf Tulsi (Ocimum basilicum). W...

Alternaria brown spot is a serious disease of fruit and foliage of citrus. This disease caused by Alternaria alternata and causes serious economical losses on susceptible cultivars in Iran. In this research, susceptibility of seven citrus cultivars including Fortune, Orlando tangelo, Mineola tangelo, Page, Clementine, Sour orange and Sweet orange (Thomson) fruits to A. alternata was investigate...

The genus Alternaria is a group of infectious/contagious pathogenic fungi that not only invade a wide range of crops but also induce severe allergic reactions in a part of the human population. In this study, two strains Alternaria longipes cx1 and Alternaria alternata cx2 were isolated from different brown spot lesions on infected tobacco leaves. Their complete genomes were sequenced, de novo ...

Metapopulation structure generated by recurrent extinctions and recolonizations plays an important role in the evolution of species but is rarely considered in agricultural systems. In this study, generation and mechanism of metapopulation structure were investigated by microsatellite assaying 725 isolates of Alternaria alternata sampled from potato hosts at 16 locations across China. We found ...

In addition to phytoalexin synthesis, the defense response of intact Citrus limon seedlings against Alternaria alternata involves both constitutive and induced enzyme activities such as chitinases (Ch) and beta-1,3-glucanases (Glu). A alternata conidial germination was prevented by protein extracts from inoculated lemon seedlings, but also by extracts from mock-inoculated specimens. On the othe...
