The project seeks to explore the interplay of valuation and inequalities in science, using the interdisciplinary and planet-critical field of forest research as empirical case. It examines which/whose knowledge is recognised on what grounds, and how social dimensions like gender and geographical location…

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

The living plant collections form the heart of the Hortus botanicus Leiden and serve as a vital resource for scientific research. By studying these collections, researchers can explore biodiversity in a unique way and conduct experiments on living material.

Climate change is increasingly threatening agriculture, as rising temperatures cause major losses in crop productivity. Plants, however, have a remarkable ability to “remember” previous heat stress.

Optimality in plant properties and processing.

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

This article discusses the coevolution of several species of the tribe Phyllantheae and moths of the genus Epicephala.

Microbes influence and respond to other organisms. This theme explores the dynamic relationships within plant and animal microbiomes, and the immune responses that govern host defense. Using model systems such as zebrafish, insects, and plants, we investigate fundamental processes and engineer microbes…

Water droplets float in a hot pan because of the so-called Leidenfrost effect. Now physicists have discovered a variation: the Elastic Leidenfrost effect. It explains why hydrogel balls jump around on a hot plate making high pitched sounds. Publication in Nature Physics on July 24.

Aspergillus niger is an important industrial producer of organic acids and enzymes producing large amounts of spent fungal biomass.

The university is making its campuses future-proof with measures for climate adaptation and biodiversity. You can read in the Sustainability Implementation Agenda 2023–2026 how we harvest rainwater, limit heat stress and make more room for greenery.

As we are working very hard to make our University more green, it is of upmost importance that you join us in our battle and start increasing the local biodiversity from your own house! Every bit will help, it is beneficial for you own mental health and most importantly it is fun! We have created this…

In a virtual game environment, one of the positive effects of anonymity is the absence of one's prejudice toward others, which can give a person the freedom to change and experiment (Bartle, 2003). This project will adopt anonymity to be added to online cross-cultural collaborative learning in higher…

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

Although plant domestication has significantly altered crop genetics and phenotypes, its effects on the taxonomic and functional diversity of plant-associated microbiomes are not well understood.

STM scanning experiments on poorly conducting materials are challenging, and can cause a distortion effect. A new model corrects for this effect, allowing physicists to better study materials in their quest to understand unconventional superconductivity. Publication in Physical Review B as Editor’s…

We investigate the processes underlying the patterns. We aim to explain biodiversity by investigating the distribution, function, development, and evolution of body forms, as well as physiological and behavioural variety among species. We collaborate with those specialized in describing, archiving,…

Increasing the efficiency of gene targeting (GT) as a genome editing tool in plants has been an important goal in plant biotechnology.

The Leiden University Green Office has some great news: you can now make the most environmentally-friendly search engine - Ecosia - your default on a public LU computer!

The Hortus botanicus Leiden connects science with the public. Through our research, we explore how people experience and appreciate nature while addressing key societal challenges.

And its application in deciphering hominin diets in palaeolithic eurasia

Which plants in the Mediterranean garden were already known to the ancient Greeks and Romans, and how were they utilized?

We aim to unravel the molecular mechanisms involved in the transformation of eukaryotic cells by Agrobacterium.

Core Facilities are shared resources that provide access to instruments, technologies and services to researchers across the Institute of Biology.

One of the main research focuses of the Hortus botanicus Leiden is to study how the current biodiversity we see today, has originated, changed, and developed over time. The Hortus wants to study the relationship between species in specific focal taxa and see how they have diverged over time.

This thesis focuses on the design and synthesis of activity-based probes and inhibitors targeting enzymes involved in the degradation of specific plant glycans.

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

The Basics and Applications to Plant Sciences will be held physical. See below for more information.

Evolutionary and ecological interactions affect species on genetic and phenotypic levels. This theme aims to understand these processes at multiple levels: from molecules to genomes to populations and to communities. Our research focuses on evolutionary responses to anthropogenic change, the role of…

Even if you have a healthy lifestyle, there's a lot to experience and learn during the Healthy University Week, from 26 to 30 October. Health psychologist Andrea Evers is enthusiastic about the week ahead. She tells us about the programme and gives us a taste of her own talk on what the placebo effect…

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

Sorghum (Sorghum bicolor) is a major cereal crop that millions of subsistence farmers in Sub-Saharan Africa (SSA) rely on. However, the scourging impact of the root parasitic weed Striga (Striga hermonthica, a.k.a. “witch-weed”) has remained a major constraint hampering the productivity of sorghum in…

Plastic pollution is a major environmental issue. Although regulation is being adopted, plastic pollution is still increasing. Effective and strict enforcement is key and NGOs and civilians can be instrumental in this.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).
