Thesis (M.S.)--University of Hawaii at Manoa, 2006. / Includes bibliographical references (leaves 140-151). / xii, 151 leaves, bound ill., maps 29 cm

Bibliography: leaves 138-160. / xii, 160 leaves : ill. ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / The 152 species of mycorrhizal fungi can be difficult to identify and quantify because the taxonomy of these fungi is based on the description of spores, which is time consuming, requires considerable expertise and cannot be assumed to reflect the situation within the root. Few attempts have been made to identify the species which are present in roots. Several approaches have been identified in previous work and the development of sensitive molecular methods for identification and quantification of two species of arbuscular mycorrhizal (AM) fungi are described in this study. Mycorrhizal fungal communities were sampled in both natural and agricultural ecosystems at two sites in South Australia. The combination of spore identification from trap culture and field-collected soil promises to be an effective means to study diversity of AM fungi in a particular system. PCR primers for Glomus mosseae and Gigaspora margarita were designed from the internal transcribed spacer (ITS) sequences of field-collected spores, with the aim of providing tools for field diagnosis. / Thesis (Ph.D.)--University of Adelaide, Dept. of Soil and Water, 2000?

The perfect stage of a species of Leptographium isolated from lesions on western white pine affected with pole blight has been described as Europhium trinacriforme and a method has been outlined for obtaining perithecia in culture. Studies on the sexuality of the fungus have revealed it to be heterothallic with two compatibility types. Cross-fertilization experiments revealed the presence of isolates which acted as either males, females or hermaphrodites. E. trinacriforme was isolated from 11 per cent of the lesions on western white pine affected with pole blight in the Interior region of British Columbia and from 84 per cent of the lesions on affected trees in the Coast region. The fungus was the only pathogenic organism isolated more than twice from lesions and it was shown to be capable of producing lesions similar in several respects to pole blight lesions. However, further data from isolation, inoculation, histological and radial growth studies have shown that pole blight lesions were not caused directly by E. trinacriforme. It is most likely that the fungus gained entrance to lesions already formed and occasionally extended them. / Science, Faculty of / Botany, Department of / Graduate
