    Notes: [Auszug] The fungus Periconia circinata m the causal agent of the 'milo disease' of certain cultivars of Sorghum vulgare var. subglabrescens (grain sorghum or milo). Other sorghum cultivars are highly resistant. Leukel3 first identified the causal agent and gave some evidence that a toxin affecting only ...

    Notes: Abstract Many fungal pathogens of plants adapt readily to changes in agriculture. Among the most revealing is a fungal group whose species produce host-selective toxins as key determinants of disease. Several lines of evidence support the hypothesis that these fungi evolved from opportunistic, low-grade pathogens by gaining new genetic information leading to toxin production; in some species, toxin production is known to be under single gene control. as a result of this evolution, these fungi became virulent and host-specialized. The best-known model cases belong to the generaCochliobolus andAlternaria; there are suggestions of evolutionary lines among these genera, with species that range from saprophytes to opportunists to specialized pathogens. Host specialization can lead to genetic isolation, a first step in speciation. Ability to produce host-selective toxin has allowed these fungi to exploit the monocultures and genetic uniformity of modern agriculture. Destructive epidemics have been the result.
