Host-Microbe Interactions is one of the four research themes of the Institute of Biology Leiden.

Leiden physicists are helping Wageningen plant researchers to study unpredictable plant embryos. For this, they are using a novel two-photon fluorescence microscope, aided by a 30 thousand euro ZonMW grant.

In our research protein translocation from Agrobacterium into yeast and plant cells is studied to obtain fundamental insights in the translocation process

Which genes are involved in woodiness and associated traits such as drought tolerance, flowering time, stem elongation, life span, and plant herbivory, and how do these gene regulatory pathways overlap?

Researchers at Leiden study group behaviour. One of their findings is that when people make sacrifices for another member of their group, it is probably instinctive. Insights of this kind enable us to better understand and influence the social processes in a neighbourhood or company.

Human impact and plant subsistence in Dutch wetlands during the Late Mesolithic and Early and Middle Neolithic (5500-3400 cal BC)

The purpose of eLaw's Working Groups is to stimulate a productive working environment for cooperation within the Center for Law and Digital Technologies at Leiden University.

Just like every other organism on Earth, plants’ ultimate goal is to survive and reproduce. In order to achieve this, they must make trade-offs between where and how to allocate their finite set of resources. Whether they put their resources and energy into their growth, reproduction or maintenance,…

Soil that is too wet, or too dry. Or with a lot or few nutrients. Due to climate change, the differences are becoming bigger, and plants must increasingly be able to adapt to survive. How do you make plants more stress-resistant? For this purpose, researchers from Leiden, along with other universities,…

Where did the new generation of antislavery activists get their inspiration to organize in large-scale pressure groups?

The program group Forensic Family and Youth Care Studies is located in the Faculty of Social and Behavioural Sciences of Leiden University near Central Station.

The unit residue group, to which the present thesis is devoted, is defined using the norm-residue symbol, which Hilbert introduced into algebraic number theory in 1897.

Beautiful microscopic specimens play the leading role in the course 'Biodiversity Plant' for first-year Biology students. Normally these are put back in storage right after the course. But not this year!

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

What legislative and regulatory questions arise when children, adolescents or elderly people use the Internet?

Harvesting rice from the same field, without planting new rice plants? A discovery may bring this scenario closer. Leiden scientists have discovered a gene that allows annual plants to grow after flowering, instead of dying. Publication on 13 April in Nature Plants.

The Global Strategy for Plant Conservation, a world-wide effort by the botanist and plant protection community, is making considerable progress in protecting plant diversity around the world, a new report says. The Hortus botanicus Leiden is one of the partners of the project.

Plants can’t run away from enemies. Still, it would like to keep life-threatening herbivores at a distance. This can be done with odours. Klaas Vrieling of the Institute of Biology Leiden found out with his team how plants change odour production to keep the munchers at a distance.

The development of space resource activities is happening now. In the absence of a clear framework to govern these activities, there is a need to examine the concepts that are being discussed in order to ensure that they meet existing treaty obligations regarding on-orbit operations and space resource…

The Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology.

Local residents, scientists and students are investigating riverbanks in Leiden for the 'Bank Plants' citizen science project. Which plant species are found where? And how can the municipality of Leiden improve its riverbank management to ensure optimal biodiversity?

On 1 April 2020, Ivan Romashchenko defended his thesis 'Related Party Transactions and Corporate Groups: When Eastern Europe Meets the West'. The doctoral research was supervised by Prof. S.M. Bartman en Prof. A. Radwan (Kaunas, Lithuania).

All kinds of reasons have been put forward for why plants apparently fail to make maximum use of the available light. None of these reasons can explain why after two billion years of evolution they are not black, like industrial photovoltaic solar cells. Are we missing something?

Producing offspring of a crop without sowing and that is even bigger than the parent plant. According to Leiden researchers this can be achieved by overstimulating a single gene that rejuvenates cells, including bringing them back to the embryonic phase.

The MicroSOS project is designed to bring together academic and industrial partners with different expertises to address challenges that agriculture is facing due to climate change and invests in the development of microbiome-based solutions towards more sustainable agricultural practices.

Within the bachelor's program of Education and Child Studies, we include the minor Kindermishandeling en Verwaarlozing: een levensloopperspectief and several other courses.

Work officially started on Schilperoortpark at the Leiden Bio Science Park on Wednesday 6 March. Town councillor Paul Dirkse and Vice-Chancellor of the Executive Board of the University Martijn Ridderbos planted the first tree together with Cas Schilperoort, grandson of Professor Rob Schilperoort, the…
