Müller, Braun & Fraussen examine the conditions under which commissioners appear in the news and which communication strategies they pursue.

2,240 plant extracts from 1,299 different plant species of Dutch origin. That’s the collection of the Dutch Extract Library, which has recently been transferred to the Institute of Biology Leiden. To plant biologist and contact person for this library Pingtao Ding this is a true treasury. ‘To bring…

In Leiden University's Vision on Sustainability 2030, biodiversity (biological diversity) is an important focus in its teaching and research and on its campuses.

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

This article offers a typology for organizational and institutional crisis management that portrays three sorts of crises: a crisis in an organization, a crisis to the organization and a crisis about the organization.

Mathematical and computational analysis of the dynamics of polar transport of the plant hormone auxin.

The Academy of Creative and Performing Arts (ACPA) of Leiden University and Art Institute West Den Haag are pleased to announce their close collaboration in the second season of the public series In the Making. This series, dedicated to the practice of research in the arts, will consist of seven public…

Both play and politics have the potential to create worlds in which new rules apply, meanings are created, and possibilities emerge for collaboration, strategy and creative solutions. In this sense, play and politics have always been very much alike. But what happens to this kinship in a post-digital…

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

Why do plants produces always produced so many slightly differing metabolites within a particular chemical class?

In September 2023, we started transforming a under-utilised outdoor space into a greener and more biodiverse garden in which all students and staff of the Schouwburgstraat can relax and enjoy.

Agrobacterium tumefaciens, a gram-negative plant pathogen belonging to the family Rhizobiaceae, is the causative agent of crown gall disease, which can affect many plant species including agronomically important ones.

How can the concept of Critical Making be expanded into a general approach that ties the critical methodology of artistic research, and the established concepts of artistic autonomy, together with contemporary creative-technological development?

Our project focuses on the analysis of decision-making processes in the European Union (EU) and explores how approaches and tools to understand decision-making found in both the Natural and the Social Sciences can be linked, knowledge between these traditions exchanged and synergies utilized. To explore…

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

Besides the Hortus being a beautiful place where visitors can relax and learn more about plants, we also facilitate botanical research. Thousands of plants are cultivated for research purposes in our greenhouses. These include tropical orchids, ferns, the soursop family (Annonaceae), the dogbane family…

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…

Optimality in plant properties and processing.

Many handwritten and illustrated archives contain a wealth of information, but are largely underexplored because they are complex and difficult for computers to decipher. The aim of this project is to develop a digital environment that resolves this challenge and connects heterogeneous archival content…

Researchers from the Plant Ecology and Phytochemistry group at the Institute of Biology Leiden (IBL) received an STW (Stichting Technologische Wetenschappen) grant for applied studies in plant herbivore resistance with potential for a novel resistance test.

In science, it is of vital importance that multiple studies corroborate the same result. Researchers therefore need to know all the details of previous experiments in order to implement the procedures as exactly as possible. However, this is becoming a major problem in neuroscience, as animal studies…

PBDL favors multidisciplinary research. Depending on the problems under investigation, PBDL establishes collaborations between experts from for example molecular genetics, molecular and electro cell physiology, biochemistry, organic chemistry, analytical mathematics, mathematical statistics and computational…

The ability to create objects and structures with our hands has been essential to human development. This ability is something modern society is at risk of losing. Leiden archaeologists gather knowledge about ancient processes of ‘making and creating’ over the centuries, knowledge that helps our current…
