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.…

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.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

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

Plant Sciences' contribution to the Biodiversity & Evolution 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.

What plants grow along ditches in the Leiden region? What does this say about vegetation quality? Could it be better? Naturalis and Leiden University's Center for Environmental Sciences are looking for your help to answer these questions.

Take a journey through the history and future of life on planet Earth.

Beneficial plant-associated microbiota, particularly those inhabiting the rhizosphere, contribute substantially to plant health through pathogen suppression, stimulation of plant defence responses, and enhanced nutrient acquisition.

Tracking early human behaviour through plant processing and -exploitation.

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.

IBL researchers use the facility to study a wide range of wildtype and transgenic plants, including Arabidopsis, tomato, barley, rice, lettuce, radish, ornamentals, and various trees. Research also involves the interaction between plants and various microorganisms and insects, providing valuable insights…

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

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.

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

Linking botanical collections, peoples, and illustrations in seventeenth century Dutch Brazil

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

The endophytic microbiota is a community of various microorganisms that reside in plant tissue. These microbes are known to promote plant health and resilience, and their members do not simply exist side by side.

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.

The bi-annual interactive seminars of the Platform for Postcolonial Readings are all about sharing our enthusiasm about our field of research and our eagerness to learn more about its theoretical intricacies. Our seminars, although informal, adopt a well-defined format. Each meeting is organized around…

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…

The Pavement Plants Citizen Science Project invites citizens to monitor plant species growing around their homes, neighborhoods, or towns. The goal is to collaboratively monitor urban flora, measuring and revealing the species richness and biodiversity of the urban ecosystem. We believe this will lead…

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.

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?

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

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 diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

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…

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.

Within the field of astronomy, understanding how galaxies grow and evolve from the Big Bang to the present day is a challenging and complex question.

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

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…

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

In the past decade many population studies have been performed with the Atacama Large Millimeter/submillimeter Array (ALMA) to understand the bulk properties of protoplanetary disks around young stars. These population studies mostly consisted of low mass stars, with relatively few of the disks around…
