First Bacterial Endosymbionts Found In The Phylum Ascomycota, Eileen Elizabeth Fitzpatrick
First Bacterial Endosymbionts Found In The Phylum Ascomycota, Eileen Elizabeth Fitzpatrick
Dissertations and Theses
Organisms belonging to the Kingdom Fungi are known to occupy a wide variety of ecological niches and are found globally in virtually all environments. Two members of the smallest of the fungal phylum, the Zygomycota, have also been found to harbor intercellular bacteria initially described as being from or closely related to organisms from the Genus Burkholderia. In this study two microaerophilic members of the species Verticilium from the phyla Ascomycota were characterized. Both appear to carry two bacterial endosymbionts. This is the first evidence of bacterial endosymbionts found within a member of the Ascomycota. Through the use of fluorescent …
Role Of The Sexual Cycle In Development Of Genotypic And Phenotypic Diversity In Gibberella Zeae, Sladana Bec
Role Of The Sexual Cycle In Development Of Genotypic And Phenotypic Diversity In Gibberella Zeae, Sladana Bec
Theses and Dissertations--Plant Pathology
Gibberella zeae (anamorph Fusarium graminearum) is a homothallic ascomycete pathogen that is responsible for causing Fusarium head blight (FHB) of wheat and small grains. In addition to causing a reduction in yield, harvested grain is frequently contaminated with trichothecene mycotoxins that are harmful for human and animal health. Use of wheat varieties with resistance to FHB is an important strategy to lower its impact. In order to produce varieties with durable resistance, we must understand the origin and degree of genetic diversity present in the pathogen population. In my research, I focused my efforts on an investigation of the …
A Phytosociological Study Of Coprophilous Ascomycete And Basidiomycete Communities From Santaquin Canyon, Utah, A. Clyde Blauer
A Phytosociological Study Of Coprophilous Ascomycete And Basidiomycete Communities From Santaquin Canyon, Utah, A. Clyde Blauer
Theses and Dissertations
Numerous reports have been published on the taxonomy and distribution of the coprophilous Ascomycetes and Basidiomycetes. No known quantitative work has been done, however, on the succession and structure of the communities formed by these higher fungi. This research was undertaken to study those two phases of the ascomycete and basidiomycete communities which grow and fruit on cow dung collected from Santaquin Canyon, Utah.
