Disentangling plant-microbe interactions under environmental change
… carbon: nitrogen (C:N) ratios and shifting plant-microbial interactions, on which plants are largely dependent. This thesis addresses the potential impacts on plant-microbial interactions under different C:N fertiliser regimes and water-availability by analysing the overall and N-cycling …

Abiotic and Biotic Factors Shaping Plant-Microbe Interactions
Symbioses between plants and soil microbes can shape plant traits and performance, population dynamics, community composition, and ecosystem function. However, the context-dependency of plant-microbe interactions remains an underexplored frontier of scientific understanding. Given that the biotic …

Comparative analysis of membrane-associated signatures at mutualistic and pathogenic plant-microbe interfaces
Plants interact with a diverse range of microbes, both above and below ground, spanning a spectrum from mutualistic relationships (where both partners benefit) to parasitic interactions (where the microbe benefits at the plant’s expense). Many interactions between plants and filamentous microbes …

SIMPLE ORGANIC FERTILIZER AMENDMENTS FOR FARMING IN DEGRADED SOILS: EFFECTS ON PLANT-MICROBE INTERACTIONS
… and microbial diversity to the soil. Overall plant biomass, culturable microbial diversity, microbial functional diversity via community-level physiological profiling, soil water holding capacity, soil microbial carbon, microbial biomass carbon, and soil carbon dioxide fluxes were all …

Pseudomonas/Brachypodium as a Model System for Studying Rhizosphere Plant Microbe Interactions Under Water Stress
… well-studied mechanisms of drought tolerance in plants, the interactions between plants and their microbiome during water stress are still poorly understood. This missing knowledge is crucial for the exploitation of beneficial microbial communities to improve the sustainability of agriculture …

The Effects Of Clinorotation In The Host Plant, Medicago Truncatula, And Its Microbial Symbionts
… to understand mutualistic relationships between plants and endophytic microbes under the influence of an altered gravity vector. Understanding the outcome of the plant-microbe symbiosis in altered gravity is vital to developing life support systems for long distance space travel and colonization …

Implementation of genetic and untargeted metabolomics to study the role of the terpene synthase vir4 from Trichoderma virens in plant-microbe interactions : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
Trichoderma virens actively interacts with plants roots in natural and agricultural ecosystems. Its ability to persist in the rhizosphere and to internally colonise plants roots is driven among others by the production of a wide diversity of specialised metabolites that encompass a complex bouquet …

GENOMIC AND PHYSIOLOGICAL INSIGHTS INTO BACTERIAL HEAVY METAL RESISTANCE MECHANISMS FOR ENVIRONMENTAL DECONTAMINATION
… balance and human health. Microorganisms and plants have evolved a range of mechanisms to tolerate, transform and immobilize these pollutants, offering opportunities for sustainable bioremediation strategies. The aim of this PhD thesis was to investigate how bacteria can contribute to the …

Evaluation of Nitrogenase Genes as Markers in Soil Microbial Community Studies
… bacteria in the environment. Two distinct plant-microbe systems were used to develop these tools, and to evaluate their utility and flexibility. The first system focused on nitrogen-fixing bacteria in the rhizosphere of salt-meadow grass (Spartina patens), a key plant species in high salt …

Interplay between selenium hyperaccumulator plants and their microbiome
The plant microbiome includes all microorganisms that occur on the plant root (rhizosphere) and shoot (phyllosphere) or inside plants (endosphere). Many of these microbes benefit their host by promoting growth, helping acquire nutrients or by alleviating biotic or abiotic stress. In addition to its …

A comprehensive microbiome analysis of wheat and its wild relatives
… that can confer competitive advantages to their plant hosts such as water acquisition, nutrient mobilization, drought tolerance, salt tolerance, and disease resistance (Chaparro et al., 2012; Sherameti et al., 2008; Zolla et al., 2013). Plant domestication and selective breeding have altered the …

Partners in space: Discordant population structure between legume hosts and Rhizobium symbionts in their native range
… of selection acting on that partner species. Plant-microbe symbioses are ecologically and economically important, but broad-ranging dispersal and dynamic genome structure in bacteria present unique challenges for understanding spatial genetic processes in these systems. Here we study the model …

Comparative Analysis of Rhizosphere and Endosphere Microbiome of Different Blueberry Species (Vaccinium sp.)
… have shown that microorganisms are recruited by plants to alleviate them during stressful conditions. Though blueberries have been cultivated for about 100 years, how the microbiome has been affected due to this is poorly understood. We hypothesized that interspecific crosses and artificial …

Induced defenses in apple fruits: linking fruit chemistry, quality, and plant-insect-microbe interactions
Plants synthesize a diverse array of phytochemicals in response to interactions with herbivores, pathogens, and commensal microbes. These phytochemicals may simultaneously enhance crop defense and quality, representing a potential pest management strategy. However, plant chemical responses to …

The functional role of root-associated microbiome and metabolome of myrothamnus flabellifolia
… four decades, extensive research on resurrection plants has yielded valuable insights into the mechanisms these plants employ to adapt during desiccation. Despite this, the role of the microbiome in desiccation tolerance, particularly in resurrection plants, remains a relatively unexplored area. …
