The overall objective of this project was to investigate the effects of the symbiotic association of plants with vesicular - arbuscular mycorrhizal fungi on the intensity of intraspecific competition and its consequences on population structure I performed four main glasshouse experiments using a non - cultivated species, Rhodanthe chlorocephala ssp rosea, or a cultivated species, Trifolium subterraneum. I grew the plants at different plant densities, under different levels of resources ( phosphorus and / or light ), in environments with homogeneous and / or patchy distribution of phosphorus (

Three studies were conducted on VA mycorrhiza in Wanagama Forest Research Center, Yogyakarta, Indonesia. The first was on VA mycorrhizal status of four forest species (Acacia mangium, Acacia holosericea, Tectona grandis, and Swietenia macrophylla) plantations and nurseries of Acacia mangium and Tectona grandis. Samples from the field were only taken during the dry season, June 1988. These four six-year old forestry species were mycorrhizal. Nursery plants had higher VAM colonization than the plantation roots and both Acacia species have higher percent colonization than the other two species. A

Bibliography: leaves 71-79. Almost 80 percent of plant taxa develop vesicular-arbuscular mycorrhizae (VAM) which are symbiotic associations between plant roots and soil fungi. The fungi are biotropic-obligate symbionts. Identification of VAM fungi is currently based on spore characteristics. Molecular techniques provide tools for better and more accurate identification of species, as well as for the examination of genetic variability occuring between individual spores of a single species.

Under field conditions, vesicles were the most frequently observed mycorrhizal structures in sugar maple, while greenhouse grown seedlings formed more arbuscules. Seasonal fluctuations of vesicular-arbuscular mycorrhizae existed. Mycorrhizal associations formed within 30 days in the greenhouse. Arbuscules were usually formed from hyphal coils and occasionally from linear hyphae spreading from cell to cell. Degenerating arbuscules were not observed. The addition of basic cations increased the number of vesicles formed and decreased the overall infection rates and seedling growth. The uptake of

Annotation:

Arbuscular mycorrhizal (AM) fungi form an obligate symbiosis with many wild and cultivated plants. The plant may benefit from improved nutrient uptake (particularly phosphorus) and resistance to drought, pests and disease. Compared to more natural habitats, arable systems support reduced diversity of AM fungi, with community structure shifted in favour of ruderal types. Physical disturbance is an important driver of these differences and reduced tillage systems might facilitate greater utilisation of the AM symbiosis as part of more sustainable production systems. In this study, the structure

Arbuscular mycorrhizal (AM) fungi have been living in association with land plants for at least 400 million years. Because they are obligate symbionts, the study of AM symbiosis has focused primarily on its plant host and progress in the molecular biology of AM fungi has been very slow. Using two different approaches, library screening and direct PCR-based assays, genetic information of AM fungi was compared across isolates and species. This allowed the study of novel DNA regions previously unexplored in AM fungi. The following species were investigated: Glomus intraradices, Glomus mosseae, Gi

Annotation:

My dissertation research examined the effect of the cultivation of insect-resistant Bacillus thuringiensis (Bt) maize on the soil environment with a goal of understanding how to obtain a balance between technological advancement and maintenance of a healthy soil ecosystem. Although Bt plants may help to reduce pesticide use, conferring benefits to farm workers and the environment, there are still unresolved questions about how the cultivation of Bt plants affects soil organisms. For this dissertation project, I used 14 different genotypes of Bt maize and non-Bt maize (Zea mays) to investigate
