Novel genes required for proper cell envelope function in the plant symbiont Rhizobium leguminosarum
… proper cell envelope development in the legume symbiont Rhizobium leguminosarum. In R. leguminosarum there is a positive correlation between mutations that affect cell envelope structure and sensitivity to peptide-rich media; therefore, I implemented an innovative transposon mutagenesis approach …

The double life of an insect pathogen: Metarhizium as a plant symbiont and its genetic diversity in coffee agroecosystems
… capacity, but more recently was recognized as a plant symbiont, being able to transfer nitrogen from insect cadavers to plants, act as plant pathogen antagonist and plant growth promoter. All those functions could be valuable as ecosystem services provided by these fungi to plants in sustainable …

Laboratory scale aerobic bioreactor conditioning of dairy processing wastewater as feedstock for Lemna minor production
… yielded poor nutrient removal and little to no plant growth, with plants reaching senescence by day 28 of the trial. It can be concluded that Lemna minor cultivation failed as a result of both A/O and IASBR operational issues (including starting pH) and insufficient seeding of cultivation tanks. …

The development of Sinorhizobium meliloti and Deinococcus radiodurans as chassis for synthetic biology applications
… Two such bacteria include the nitrogen-fixing plant symbiont, Sinorhizobium meliloti, and the polyextremophile, Deinococcus radiodurans. While some progress has been made toward the development of these chassis, further strain and tool developments are required to unlock their full potential. …

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 …

The analysis of Metarhizium robertsii potential as endophytic plant root coloniser, plant growth enhancer and antagonist to bean root pathogen Fusarium solani f. sp. phaseolis.
… fungus Metarhizium robertsii also colonizes plant roots endophytically, thus showing potential as a plant symbiont. M robertsii is not randomly distributed in soils but preferentially associates with the plant rhizosphere when applied in agricultural settings. Root surface and endophytic …

Similarities and variations of the enterobacterial chemotaxis paradigm in Sinorhizobium meliloti
Sinorhizobium meliloti is a nitrogen-fixing endosymbiont of the legume Medicago sativa commonly known as alfalfa. It uses flagellar rotation and chemotaxis to seek roots of host plants to inhabit. This symbiosis serves as a great model system for studying biological nitrogen fixation and …
