How do plant defense genes get activated?

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…

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

This book considers the porous relationship between legality and illegality in Brazil, a country that presages political and societal changes in hitherto unprecedented dimensions.

This book celebrates Maarten Mous, professor of African Linguistics at Leiden University.

This dissertation studies the construction of Franklin Delano Roosevelt as a cultural icon in American memory, particularly by FDR himself.

The book Global Gold Production Touching Ground: Expansion, Informalization, and Technological Innovation is edited by Boris Verbrugge and Sara Geenen. In recent decades, gold mining has moved into increasingly remote corners of the globe. Aside from the expansion of industrial gold mining, many countries…

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

This book rovides an economic history of Portugal over the course of eight centuries, from 1143 through to 2010 and situates Portugal's economic growth within the context of European development. It also responds to fundamental questions about when, how and why the economy expanded, stagnated or co…

This thesis focusses on the temperature structure in protoplanetary disks. The relation between structures seen in the dust and gas-phase molecules is investigated.

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

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?

Identifying natural plant-associated bacteria that provide targeted inhibition of pathogens through the production of antimicrobial peptides.

Optimality in plant properties and processing.

Nienke van der Marel has been awarded the New Horizons Prize in physics for her pioneering research on planet formation. This prize is given to young, promising researchers in physics or mathematics. The astronomer and her colleagues found the first observational evidence for 'dust traps' in disks around…

The research provides insight into disease behavior in both rural and semi-urban areas in Serengeti in Tanzania.

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…

How does the extracellular matrix coordinate endothelial cell behavior during angiogenesis, and how do metabolic waste-products and matrix-degrading enzymes produced by the tumour modify the extracellular matrix so as the change the cellular coordination?

Animal Sciences’ contribution to the Bioactive Molecules research theme includes research on molecules from natural sources, such as plants, insects, and snake venom, with the aim to identify novel anti-cancer, anti-inflammatory, anti-microbial, and anti-diabetic agents.

In 2024, many of our students and staff won great prizes and secured important research grants.

Leiden researcher Dr Ben Zonneveld has determined the size of the genome - the amount of DNA per nucleus - of wild tulips. His conclusion is that there are more than 87 wild species. Various possibly new species have been discovered.

Information about the products of the extract library.

We exploit secondary metabolites of plant to develop pharmaceutical compounds and we genetically modify plant genomes to improve crops.

Biology student Britt van Kasterop has received a Holland Society Young Talent Award for her excellent results in the first year of study. The online awards ceremony took place on 30 November.

Can metabolomic profiling be used to predict resistance against insect herbivores in plants?
