Transposable Elements In Fusarium Oxysporum & Growth Inhibition Of Fusarium Oxysporum Using Pepper Extracts, Taylor Aguiar Jan 2018

Transposable Elements In Fusarium Oxysporum & Growth Inhibition Of Fusarium Oxysporum Using Pepper Extracts, Taylor Aguiar

Masters Theses

The following contains two projects focused on the fungal pathogen, Fusarium oxysporum. The first project was purely computational in the examination of transposable elements (TEs), which are mobile sequences with the ability to multiply and move in their host genome. In F. oxysporum, TEs such as miniature impala elements are associated with the secreted in xylem gene that are related to its virulence over its host. The F. oxysporum species complex can be utilized as a model system for the examination of TE content and TE expression during the infection cycle. To find whether TEs play a role in the ...


Biological Species Concepts In Eastern North American Populations Of Lentinellus Ursinus, Andrew N. Miller Jan 1997

Biological Species Concepts In Eastern North American Populations Of Lentinellus Ursinus, Andrew N. Miller

Masters Theses

As part of a biosystematic study of the Lentinellus ursinus species complex, field and herbarium specimens from North America, Central America, and Europe were examined. Single basidiospore isolates from basidiomata collected in Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Tennessee, North Carolina, Wisconsin, Costa Rica, and Austria were crossed in all possible combinations to determine the mating system operating in each population. All populations exhibited bifactorial or tetrapolar mating systems. Tester strains were then crossed to identify intercompatible populations and to determine if morphological species in the L. ursinus species complex are congruent with biological species. Three biological species were recognized ...


A Biosystematic Study Of Panus Conchatus (Basidiomycetes; Agaricales), James Edward Johnson Jan 1992

A Biosystematic Study Of Panus Conchatus (Basidiomycetes; Agaricales), James Edward Johnson

Masters Theses

As part of a biosystematic study of Panus conchatus (Bull.: Fr.) Fr., North American and European herbarium specimens from the Field Museum and the University of Michigan were examined and a description of the taxon prepared. Tissue and single spore isolates were obtained from basidiocarps collected in Illinois. Single and polyspore isolates were obtained from a collection made in Switzerland by R. H. Petersen. Culture mat analyses were completed on several media and the taxonomic value of cultural characters assessed. Based on this study, the identification of somatic cultures by cultural characteristics is unlikely. Single spore isolates from the Illinois ...


A Cytomorphological Study Of Podospora Curvicolla (Winter) Niessl, Stephen F. Tomasino Jan 1982

A Cytomorphological Study Of Podospora Curvicolla (Winter) Niessl, Stephen F. Tomasino

Masters Theses

A cytomorphological study was performed on Podospora curvicolla, a saprophytic Pyrenomycete. Major emphasis was placed on three important features: (I) ascocarp formation and development, (II) centrum structure and (III) ascus development and structure. A comparison with other studies of Podospora and with a genus generally considered closely related, Sordaria, was made to this present study of P. curvicolla.

Initial perithecial formation in P. curvicolla is indicated by a spherical mass of hyphae which may include filaments from many vegetative hyphae, but no apparent ascogonia or antheridia were observed. As the young perithecium matures in P. curvicolla, differentiation of the perithecial ...
