Researchers in the field of Psychoneurobiology examine the interactions between body and mind. They investigate the effects of stress as well as the effect of placebos and nocebos, which can…

The mission of the Plant Science research programme is to contribute to the sustainable production of high quality crops, flowers and high-value bio-based products. This is realised by generating fundamental knowledge of basic biological processes related to development of plants and their interaction…

In our lives we often have little attention or appreciation for plants, let alone the ones we commonly call weeds. This inattention for plants has been described as plant blindness. The Stoepplantjes project aspires to decrease plant blindness by changing the image of weeds and using citizen science.…

This research project of the Catholic University of Leuven was created in 1976 by Professor Dr Pierre Vermeersch, who assumed its direction until 2003. The present director is Professor Dr Philip Van Peer.

The HARVEST project explores the dietary choices that our hominin ancestors and relatives made, by recovering information on what they consumed, and how factors like environmental variation, intrinsic biology, and development of food processing technologies could have influenced their decisions.

Which microorganisms live near and inside plant roots? How do they contribute to plant health? Can microorganisms be employed in plant protection?

The mission of the Plant Sciences cluster is to contribute to the sustainable production of high-quality crops, flowers and high-value bio-based products, and to contribute to the maintenance and restoration of biodiversity in natural ecosystems. This is realised by generating fundamental knowledge…

A Diachronic Perspective on the Aegean

This part of the research programme is carried out by Prof. Dr. René Cappers. It focusses on the continuities and changes in the use of plants at Late Neolithic Tell Sabi Abyad, as well as on their implications as proxy evidence for the climate change c. 6200 BC. Parallel to the design of the other…

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

In this book, Peter Akkermans provides a systematic overview of the Halaf culture of the 6 th millennium BC in the Syrian portion of the valley of the Balikh River, a tributary of the Euphrates.

We study the link between the acoustic, behavioral and physiological health of birds and prominent pollution factors. We aim to explore causation through experimental studies on detrimental factors like traffic noise, particulate matter and chemical toxins. Our primary target is scientific progress…

How is Pol θ responsible for T-DNA integration, and how do other DNA double-strand break repair pathways interact with Pol θ? How may we manipulate T-DNA integration to stimulate error-free integration at a predetermined genomic site?

Basketry, cordage and textiles made of plant fibers or bark are rarely preserved in the archaeological record. By means of experimental archaeology and microwear analysis, we obtain indirect evidence about this important craft.

A three-volume standard work on galls in Europe. Author Johannes C. (Hans) Roskam is associate professor emeritus in Evolutionary Biology and currently guest at Leiden University.

We examine how soil-derived legacy effects of plants structure natural ecosystems, determine aboveground plant insect interactions, and how we can use soil legacy effects to restore degraded ecosystems.

The Plant BioDynamics Lab (PBDL) is a laboratory dedicated to experiments designed to develop and validate quantitative mathematical models of dynamical processes in biology. The principal objective of developing these models is to make quantitative predictions about these processes.

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

Papers presented at a colloquium, held in honour of Professor Dr. P.J.R. Modderman, Leiden, 3-7 May 1982.

Plant Sciences' contribution to the Evolution & Biodiversity research theme is to understand what are the key drivers of plant biodiversity during evolution with a focus on plant life history and resilience traits and develop tools to restore and maintain plant biodiversity.

Plant Sciences' contribution to the Bioactive Molecules research theme is to identify new plant bioactive molecules, and unravel their mechanisms of action in plant development or health, and the regulatory networks and (bio)synthetic pathways required for their production.

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

How can we manipulate the biotic and abiotic environment to increase thrips resistance in tomato and chrysanthemum? More specifically we ask: How can plant secondary metabolites that are not soluble in water be delivered to plants in seed coating or root dipping treatment? Can bacteria be used to…

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…

Did early farmers deliberately use animal manure on their fields?

In this episode we talk with Mara van der Meulen about prosocial behaviour and social exclusion in children. Van der Meulen also explores the role of genetics and environment in the development of social behaviour. To find out more about her research on why some children are beter able to develop their…

This volume of Analecta Praehistorica Leidensia focuses on how local communities in prehistory define themselves in relation to a bigger social world.

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…

The Hortus botanicus Leiden has one of Europe’s largest collections of living plants from the Asian region. This rich resource is no longer the sole domain of botanists. Extraordinary professor Paul Kessler studies what the Hortus botanicus Leiden can offer research, higher education and the public…

How do plants lure microscopically small 'support teams' into their roots for protection against diseases? And what functions are activated in the microbes and the plants?

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

Plant Sciences' contribution to the Host-Microbe Interactions research theme is to dissect how microorganisms and microbiomes interact with the plant host and the insects on those plants, and how these insights may be harnessed to improve plant growth and health, by steering microbiome composition and…

Plant-microbe interaction resulted in different physio/chemical responses by host plant and interacting rhizobacteria.

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.
