Understanding population responses to novel environments is a central concern of both evolutionary biology and ecology (Maynard Smith 1989; Bradshaw 1991; Hoffman and Parsons 1991; Peters and Lovejoy 1992; Kareiva et al. 1993). Populations subject to substantial environmental stress, such as occurs during colonization attempts, human-mediated introductions or reintroductions, orglobal climatic ...

background botulism is a toxin-induced paralytic illness characterized by cranial nerve palsies and descending flaccid paralysis. botulinum toxin is regarded as the most lethal ever-known substance. the diagnosis in sporadic cases and even in small outbreaks is the main physicians’ challenge. the aim of this study was to assess clinical presentations of 80 cases of botulism referred to loghman ...

Alternaria brown spot disease is caused by the alternata tangerine pathotype, which relies on ACT-toxin for infection. At present, all identified biosynthesis-related genes are multi-copy genes. In this study, we summarized advances in important host-specific toxins (HSTs), and listed key required pathogenicity of A. pathotype. Toxin virulence test results revealed that different citrus species...

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...
