Once a month, the Europa Institute comes together to hear from its own staff members, guest researchers, or external scholars about their research plans, work in progress papers, or recently concluded projects relevant to European law. The Food for Thought-series is organised by Melanie Fink.

What are trait-trait relationships in wetlands? To what extent the so-called leaf economics traits deviate from terrestrial ecosystems? How traits specific to wetland plant relate to plant strategies? What’s the relationship between wetland plant traits to the ecosystem functioning (e.g. productivity,…

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

How do different communities of residents in The Hague perceive and manage food waste in relation to citizenship (rights and responsibilities)?

By placing food at the centre of investigation, this Minor explores current-day debates on political, environmental, economic and cultural change at both the local and global levels.

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

How is vegetative development regulated in plants and how does this affect a plant’s life history strategy?

How and why latex bearing plants select specific chemical compounds for eco-chemical interactions with its biotic factors?

Education in (Chinese) Medicinal Plants associated to the Hortus botanicus in Leiden - Which Traditional Chinese Medicinal plants can be grown in the Hortus? - Establishing of a database which Chinese medical plants are available in Dutch Botanical Gardens - Data validation (correct identification,…

The double issue of kritisk etnografi – Swedish Journal of Anthropology, has a question: Is Europe skilling for sustainable food? The two guest editors, Professor Maris Boyd Gillette from the University of Gothenburg and Professor Cristina Grasseni from Leiden University, have convened an esteemed…

The availability of complete plant genome sequences together with the ever increasing amount of data on the molecular, cellular and physiological mechanisms of plant development require mathematical and computational models to obtain a complete overview of and generate new insights into the quantitative…

Cristina Grasseni, Federico de Musso, Ola Gracjasz, Maria Vasile, Vincent Walstra and Marilena Poulopoulou are part of the 'Food citizens?' Research project.

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

Today, humanity produces sufficient calories, in theory, to feed the 7.7 billion people on the planet: the amount of food produced per person on the planet has gone up more than 40% since the 1960s. Yet, ironically, the prevalence of undernourishment – which had been declining for decades – has started…

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

Identification and characterization of components of DNA repair pathways and their role in Agrobacterium T-DNA integration and repair of CRISPR/Cas induced DSBs.

Trigonostemon Blume is a plant genus in the family Euphorbiaceae comprising 59 species.

This thesis describes how different colours of light affect various aspects of the growth and development of Arabidopsis and tomato plants⁠.

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).

Microbiome composition of the spermosphere and the rhizosphere of wild and modern bean accessions grown in an agricultural and a native soil from Colombia was characterized by metagenomics and cultivation-dependent approaches.

Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

Our focus is to optimize the fungal cell wall to both increase chitin production and chitin extractability.

Food relations (through production, distribution, circulation, exchange and waste) represent the embodiment of our relation to the environment.

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

The major objective of the study is to ascertain how Japanese colonialism affected the manner in which food was produced, processed, prepared and consumed in the colony, and how new attitudes towards these practices were constructed.

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…

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

We showed that constitutive and inducible chemical and morphological defenses against Western flower thrips differ between tomato and chrysanthemum plants.

Salicylic acid (SA) is a plant hormone, which is involved in the defense responses to pathogens and to abiotic stress, and in the regulation of plant growth and development.

National Meat Free Week (Nationale Week Zonder Vlees, 7–13 March) is an initiative to reduce meat consumption.
