The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

Plant diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

It is a common technique in global optimization with expensive black-box functions to learn a surrogate-model of the response function from past evaluations and use it to decide on the location of future evaluations.

This dissertation presents the synthesis and evaluation of antibody recognition for various capsular polysaccharide (CP) fragments of Staphylococcus aureus (S. aureus).

Kinase inhibitors are key therapeutic agents, particularly in oncology, yet their clinical efficacy is often hampered by off-target effects and limited understanding of their cellular target profiles.

During post-embryonic development into adults, animals face an environment that fluctuates constantly. For example, in nutrient availability, temperature, and osmolarity (e.g., salt concentration).

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

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

Triple-negative breast cancer (TNBC) constitutes a small subtype (~15%) of breast cancer, but causes the majority of breast cancer-related deaths.

The goal of the research presented in this thesis was to explore the chemical space of ruthenium(II) photocages, investigate their ability to host potent chemotherapy drugs, and to red shift the activation wavelength of the most promising PACT candidates to conduct biological studies.

In this Ph.D. thesis, we characterized two novel upstream regulators of JUB1, HB40, and HB22, in Arabidopsis thaliana. In Chapter 2, we described functions of HB40 in modulating growth and development via the regulation of JUB1 and GA inactivation genes GA2OXs.

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

The PID-directed shift in PIN polarity has been broadly accepted as one of the essential mechanisms for the regulation of auxin transport polarity.

In 2019 startte LUGO een petitie met het verzoek om een ambitieuze duurzaamheidsvisie voor 2030. Deze petitie is geformuleerd op basis van wat LUGO haalbaar achtte in plaats van op de beperkingen van nu. Wij vinden dat duurzaamheid een van de kernwaarden moet zijn van het volgende centrale beleidsplan…

Pancreatic ductal adenocarcinoma (PDAC) is among the cancers with the highest mortality rate, despite a relatively low incidence.

This thesis describes how to scale down concepts of macroscopic mechanical metamaterials to the thermal scale using a system of flexibly-linked colloids.

In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

Breast cancer (BC) is a clinically and biologically heterogeneous disease.

Anionic particles play an important role in biological systems where they fulfil many essential functions for cells.

Drug development critically depends on preclinical models that mimic human physiology, yet traditional two-dimensional cultures and animal models often lack predictive power.

Dit project onderzoekt de rijke taalkundige geschiedenis van de cruciale taalgroepen in Oost-Afrika en omvat een zoektocht naar woorden die wijzen op eerder verloren talen. Deze resultaten, gecombineerd met recent archeologisch en genetisch onderzoek, zullen bijdragen aan een nieuw begrip van de vroege…
