Victoria blight of oats is caused by the fungus Cochhobolus victoriae. This fungus is pathogenic due to its ability to produce the host-selective toxin victorin. Previously, a 100-kD protein that binds victorin in vivo only in susceptible genotypes was identified as
the P protein of the glycine decarboxylase complex (GDC)....
In vitro growth of twelve isolates of Tither spp., the true truffles, was quantified by an agar-melt procedure. All isolates grew
poorly on media commonly used for the culture of mycorrhizal fungi, but responded markedly to the addition of nitrate, as well as other
inorganic ions, to malt and potato-dextrose...
Replication of plasmid molecules containing either a left-end or a
right-end adenovirus origin was investigated. When the plasmids were
linearized to expose their respective adenovirus termini, mixed, and
transfected with helper adenovirus DNA into the human 293 cell line, a
new molecule was detected. The new molecule was the size...
The work in this thesis has provided conclusive genetic evidence
that "panhandle" intermediates form during adenovirus replication.
Adenovirus chromosomes lacking 51 by from their left -hand termini
are infectious and capable of regenerating the missing origin
sequence. Yet if an entire inverted terminal repeat is removed, the
adenovirus chromosome is...
