Common Accommodation Mechanisms for Mutualistic and Detrimental Fungi in Oryza sativa (Rice) Roots
Rice roots engage in symbiosis with ancient symbiotic fungi such as R. irregularis, whilst resisting invasion of the detrimental fungus M. oryzae, a major causative agent of the rice blast (leaf) disease. M. oryzae can also invade rice roots with simple non-melanised hyphopodia formed on the rice …

Mikrobielle Ökologie N-Acyl-L-Homoserinlacton-produzierender Bakterien in der Rhizosphäre von Tomatenpflanzen
… complex soil system. The characterisation of the root colonisation behaviour was performed using confocal laserscanning microscopy (CLSM) and cell counting of bacteria. Fluorescence in situ hybridisation (FISH) and terminal restrictions fragment length polymorphism (t-RFLP)-techniques were used to …

The development of a transparent soil and its application in imaging root trajectories and root bacteria interactions
… implications. These processes include root growth and microbial interactions with roots and soil particles and they influence the efficiency of crop production and, in turn, global food security. The observation and imaging of these below-ground processes is difficult due to the opacity …

Assessing the involvement of BslA in plant-root associated biofilms
… diseases. The formation of biofilms on plant roots is often vital for biocontrol. Biofilms are complex multicellular communities of bacteria interacting with each other, and encased in a self-produced extracellular matrix. The matrix is composed of exopolysaccharides, proteins and nucleic …

Strategies to increase production of betalain pigments and their use as SynBio tools
… and $\textit{Nicotiana benthamiana}$ roots. By expressing the betalain biosynthetic genes under plant symbiosis specific promoters, we were able to effectively restrict betalain production to areas of the root engaging with fungal colonisation. We also showed that this is an efficient …

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 …
