Comparative Genomics of Pathogens Causing Brown Spot Disease of Tobacco: Alternaria longipes and Alternaria alternata
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 ...
متن کاملPurification of Host- Specific Toxin from Iranian Isolates of Alternaria alternata, Causal Agent of Brown Spot Disease of Tangerine
Brown spot disease caused by Alternaria alternata (Fr.: Fr.) Keissl is a serious problem forproduction of tangerines and tangerine hybrids in Iran. The Tangerine pathotype causes brownspot disease on young leaves and immature fruits of limited varieties of mandarins and tangerines(Citrus. reticulata Blanco). Specificity in the interaction between tangerine and the pathogen isdetermined by a hos...
