Control of arbuscular mycorrhizal colonisation : studies of a mycorrhiza-defective tomato mutant / Lingling Gao.
This thesis characterises a mycorrhiza-defective tomato (Lycopersicon esculentum Mill.) mutant, rmc, with respect to fungal colonisation patterns and plant defence reactions during interactions with different species of arbuscular mycorrhizal (AM) fungi, root fungal pathogen Rhizoctonia solani and …

A FAMILY OF SMALL SECRETED PROTEINS FROM RHIZOPHAGUS IRREGULARIS CONTRIBUTE TO ARBUSCULAR MYCORRHIZA SYMBIOSIS
Arbuscular mycorrhizal (AM) fungi are able to colonize more than 80% of all land plants, providing several benefits to their host, such as an increased nutritious status or an increased resistance to pathogens. The molecular mechanisms underlying plant colonization are still unknown, due to the …

Response of wheat (Triticum Aestivum)to Vesicular Arbuscular Mycorrhiza(VAM) and Trichoderma on grain yield and uptake of phosphorous in Acidic Soils
… four levels (Trichoderma, Versicular arbuscular mycorrhiza (VAM), VAM/Trichoderma and control). First phase of the experiment was isolation of VAM spores from the soil and the second phase was inoculation of wheat seeds with VAM and Trichoderma species at planting. Indigenous spores of VAM were …

Effects of arbuscular-mycorrhizal fungal colonization on management of saline lands
… was to evaluate the importance of arbuscular-mycorrhizal ( AM ) colonization of plants in management of saline lands. Some aspects of application of AM fungi in revegetation of saline lands are also reported. Effects of AM pre-inoculation on mycorrhiza-responsive and non-responsive plant …

The effects of different concentrations of phosphite on ectomycorrhiza formation by Pisolithus tinctorius in Castanea dentata
… affect the plant’s ability to form ectomycorrhizas, the mutualistic symbioses between tree roots and certain soil fungi, and the phosphites themselves may be phytotoxic at high doses. Container-grown chestnut seedlings were treated with six phosphite solutions ranging from 0.0g/l to …

Unearthing the mechanisms of the mycorrhizal-bacterial symbiosis in plant roots using a metatranscriptomic approach
Arbuscular mycorrhizal fungi participate in a widely conserved symbiosis with a majority of land plants which provides plant hosts with increased capability for soil nutrient uptake. These endosymbiotic fungi are themselves colonized by a diverse group of bacteria, including both parasitic and …

Characterisation and expression of Receptor-like Cytoplasmic Kinases in Medicago truncatula during Rhizobial and Arbuscular Mycorrhizal symbioses
… to be necessary for symbiosis with arbuscular mycorrhiza fungi (AMF). These common genes make up part of a signalling pathway known as the common symbiosis pathway (CSP) which serves to prepare the plant for the entry of the symbiont into the root. Although the core members of this signalling …

Tree community assembly and biogeochemical processes along an elevational gradient in western Panama
… evaluates how edaphic factors, climate, and mycorrhizal associations drive tree community assembly, C storage, and biogeochemical processes along environmental gradients. Using a set of twelve plots in a premontane forest established along a natural fertility gradient, I was able to determine …

Map-based cloning of the NIP gene in model legume Medicago truncatula.
… plant that is used to study symbiosis with mycorrhiza and with the bacteria Sinorhizobium meliloti. The focus of this work is the M. truncatula nodulation mutant nip (numerous infections and polyphenolics). The NIP gene plays a role in the formation and differentiation of nodules, and …

Liverwort-Fungal Associations: Novel Symbioses In Polar Regions?
… phosphorus. These associations, referred to as mycorrhiza, are hypothesised to have been a key factor in the colonisation of the land by plants. However, we still know very little about fungal symbioses in one of the most ancient groups of land plants — the liverworts — and in the bryophyte …

Strategies to increase production of betalain pigments and their use as SynBio tools
… reporter system to visualise arbuscular mycorrhiza symbiosis processes in in $\textit{Medicago truncatula}$ and $\textit{Nicotiana benthamiana}$ roots. By expressing the betalain biosynthetic genes under plant symbiosis specific promoters, we were able to effectively restrict betalain …

Invisible to arbuscular mycorrhizal fungi: Positional cloning and characterisation of a novel arbuscular mycorrhizal mutant in Zea mays
Arbuscular mycorrhizal fungi from the Glomeromycotina form a beneficial symbiotic relationship with the root systems of a majority of plant species, enabling plants to profit from increased phosphate uptake efficiency. Further understanding of this interaction may prove vital in meeting the …

Harnessing the genetic potential for arbuscular mycorrhizal symbiosis in rice
Arbuscular mycorrhizal fungi (AMF) have long been recognised to form a mutually beneficial symbiosis with over 80% of land plants present today. The symbiosis provides an integral link to mineral nutrients in the soil (Bago et al., 2000; Jakobsen & Rosendahl, 1990; Smith & Read, 2008) and this has …
