Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

This thesis deals with the use of sound in interactions in the context of participatory systems and data sonification. We investigate an interactive environment where participants perceive information of the data through sound elements.

This thesis introduces a relational interaction model and a practical tool for describing, visualising and generating interactive dialogues.

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

Cardiovascular disease is the leading cause of death worldwide.

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

In this thesis, the role of plant-mediated soil legacy effects in shaping aboveground plant-insect interactions was investigated.

In this thesis we examine certain phenomena in symplectic topology which are related to the theory of isolated singularities.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

Modeling and analysis of cyber-physical systems are still challenging. One reason is that cyber-physical systems involve many different parts (cyber or physical), of different nature (discrete or continuous), and in constant interaction via sensing and actuating.

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Op 21 februari 2019 verdedigde Ruben Zandvliet zijn proefschrift 'Trade, Investment and Labour: Interactions in International Law'. Het promotieonderzoek is begeleid door promotor prof. dr. N.J. Schrijver.

The primary goal of this research is to deepen our understanding of substrate-enzyme interactions in Glycoside hydrolases. For this purpose, Bacillus circulans xylanase (BcX) has been selected as a well-established model to examine the Michaelis complex and glycosyl-enzyme adduct.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

The endophytic microbiota is a community of various microorganisms that reside in plant tissue. These microbes are known to promote plant health and resilience, and their members do not simply exist side by side.

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

Curved single crystals provide variable, but well-defined surface structures.

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

In deze dissertatie onderzoekt Galikyan hoe de multidimensionaliteit van gegevens over interactie tussen studenten en de veelzijdigheid van deze interactie van invloed zijn op de meting van interactie tussen studenten in digitale leeromgevingen.

The overarching goal of this PhD thesis is to investigate the taxonomic and functional diversity of yeasts in the wheat phyllosphere and their interactions with the mycotoxigenic fungal pathogen Fusarium graminearum.

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Dit proefschrift betreft een interpretatief onderzoek naar de wijze waarop leraren hun dagelijkse leraar-leerling interacties interpreteren in termen van het belang van hun leerlingen.

The research presented in this thesis explores the chemotherapeutic potential of metal-based compounds as chemotherapy agents, with an initial focus on the synthesis and DNA interaction studies of platinum and palladium compounds utilizing the [Pt(bapbpy)]2+ scaffold. The study identifies intercalation…
