The interaction between several species of arbuscular mycorrhizal fungi, micropropagated strawberry plants and <i>Phytophthora fragariae, </i>the pathogen that causes red stele disease of strawberry plants, was investigated. The optimum temperature for germination of zoospore cysts of <i>P. fragariae in vitro </i>was found to be 15°C, and growth of the emerging germ tube was significantly orientated towards the strawberry root tip. Cyst germination was reduced in the presence of a mycorrhizal strawberry root. Elsanta was more susceptible to <i>P. fragariae </i>than the cultivar Rhapsody. A low

Two field studies were conducted to assess the potential benefit of arbuscular mycorrhizal (AM) inoculation of elite strawberry plants on plant multiplication, and fruit yield, under typical nursery conditions, in particular soils classified as excessively rich in P.

Résumé :

Sexual reproduction is an important process amongst eukaryotic organisms, with one function being to maintain genetic variation. The idea that complex eukaryotic species can persist for millions of years in the absence of sex defies fundamental evolutionary dogma, yet a group of organisms known as ancient asexuals were thought to have evolved clonally under deep evolutionary time. Prominent among these are the arbuscular mycorrhizal fungi (AMF), which are obligate plant symbionts that colonize the root cells of plants and extend their hyphae into the soil assisting the plant in acquiring key n

Arbuscular mycorrhizas (AM) are mutually beneficial symbiotic associations between the roots of plants and certain Zygomycetous fungi. The role of AM fungi in coastal sand dunes has been explored in many parts of the world, though little work has been conducted in South African dune systems. This study aimed to investigate the presence and extent of mycorrhizal colonisation of a coastal sand dune in South Africa. The roots of five plant species (Scaevola plumieri, Arctotheca populifolia, Ipomoea pes-caprae, Ehrharta villosa and Chrysanthemoides monilifera) were sampled along a foredune profile

Résumé :

The arbuscular mycorrhizal (AM) symbiosis is a mutualistic association between plant roots and fungi that belong to the Phylum Glomeromycota. In this symbiosis, the plant provides the fungus with carbohydrate and gets phosphorus in return. Study of these fungi is fettered because of their obligatory symbiotic nature and lack of basic knowledge of their genetics. These fungi produce multinucleate spores and it is not clear whether nuclei within a spore are genetically similar or dissimilar. In this thesis, we discuss techniques that address some fundamental questions about the organization of g

The main experiment compared the fungi under two P levels in soils.

Arbuscular mycorrhizal fungi (AMF) are soil fungi associations with the majority of terrestrial plants. These fungi may affect a wide range of ecosystem processes from primary productivity to soil stabilization. Understanding the patterns and controls of AMF abundance during succession soil will be critical to predicting and managing ecosystem development. The work presented in chapter 2 is the first to describe changes in the abundance of mycorrhizal types during development of an unregulated floodplain.

Résumé :

Arbuscular mycorrhizal (AM) fungi are naturally occurring in roots of terrestrial plants. AM fungi are capable of benefiting the host plant through various mechanisms such as enhanced nutrient supply, alleviation of environmental stress and inhibition of plant fungal pathogens. AM fungal spore-associated bacteria have been previously isolated and shown to have plant growthpromoting (PGP) abilities by several authors. Some bacterial isolates are able to promote AM fungal colonisation of host plants and are known to be mycorrhizal helper bacteria (MHB). This study focused on the isolation of AM

However, nematodes did not affect the growth response of red clover to VAM infection even though there was an in

A fundamental goal in ecology is to examine diversity patterns of naturally occurring communities and link these patterns to underlying structuring processes. Despite the importance of arbuscular mycorrhizal (AM) fungi in natural ecosystems, the majority of studies to date have focused on community structure in a restricted set of systems (mainly temperate grasslands, old fields, and agricultural ecosystems). This is highly limiting because it is well known that the functioning of mycorrhizal symbioses can be influenced by biotic and abiotic environmental factors, and thus our understanding of

Terrestrial orchids make up one of the most threatened groups of plants in Australia and the genus Arachnorchis is listed as the fourth most threatened. The process of propagation and re-introduction of terrestrial orchid plants to the wild has proven difficult, and so far, nearly impossible for some species. This may be partly because terrestrial orchids form complex relationships with mycorrhizal fungi and in genera like Arachnorchis the dependency on the fungus appears acute.

Arbuscular mycorrhizal fungi (AMF) can form a mutualistic symbiosis with over two-thirds of all land plants, providing phosphorus and/or nitrogen in exchange for carbon.

Important greenhouse gases (GHG) including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) can be influenced by these factors, yet to date the interactions between AMF and soil GHG fluxes are surprisingly understudied.

Managed grazing, involving large animals destined for human consumption, covers more than 25% of the land surface and has the capacity to alter ecosystems, often leading to desertification, woody encroachment, and deforestation (Asner et al 2014).
