Using EcoFab 2.0 devices and omics services at JGI, we will examine a plant growth promoting microbial community during interaction with different plant species.

Agrobacterium-mediated transformation (AMT) has abundantly been used for scientific research for identifying valuable traits.

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

This thesis describes how different colours of light affect various aspects of the growth and development of Arabidopsis and tomato plants⁠.

Trigonostemon Blume is a plant genus in the family Euphorbiaceae comprising 59 species.

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

Chronic inflammatory skin diseases such as psoriasis and atopic dermatitis affect both the physical and psychological well-being of millions of patients, leading to persistent symptoms like itchiness and sleeplessness. These conditions often result in decreased productivity and quality of life overall,…

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.

There are about 35,000 students with chronic illnesses in the Netherlands. If they cannot receive education in the classroom, they may be able to do so from home or a hospital with hybrid education. The question in this study is: how can interaction with the teacher and fellow students be promoted?

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

Microbiome composition of the spermosphere and the rhizosphere of wild and modern bean accessions grown in an agricultural and a native soil from Colombia was characterized by metagenomics and cultivation-dependent approaches.

The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

Sprayable plant-based adhesives for crop protection against thrips Some plants, such as sundew and tomato, protect themselves with sticky hairs that repel or even trap arthropod herbivores.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

We showed that constitutive and inducible chemical and morphological defenses against Western flower thrips differ between tomato and chrysanthemum plants.

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

Salicylic acid (SA) is a plant hormone, which is involved in the defense responses to pathogens and to abiotic stress, and in the regulation of plant growth and development.

Amanda gave a talk in Vienna on the role of plant foods in human evolution, including a small teaser of the FoodWays project! The talk will soon be available on the HEAS YouTube Channel.

Persistent somatic symptoms are long term symptoms that lack a clear medical explanation. These symptoms have a high prevalence where most people know someone who experiences such symptoms or they experience such symptoms themselves. Symptoms can vary greatly in and between people. While one person…

How can we make agricultural production systems more sustainable as the worldwide demand for healthy, safe food continues to grow? How can we develop healthy new food crops that have higher yields while requiring fewer harmful chemicals?

The AT-Hook Nuclear Localized 15 (AHL15) gene belongs to a plant-specific gene family of DNA-binding proteins. Overexpression of AHL15 in Arabidopsis thaliana delays developmental phase transitions whereas its loss of function causes a slight acceleration.

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

This thesis investigates the relations between metabolism and anatomy through the use of Magnetic Resonance Imaging (MRI).

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

The disappearance and reappearance of species of plants in the Netherlands is a normal phenomenon. In the period from 1981-2000 the number of plants to have disappeared was considerably lower than previously, whereas the number of species rediscovered is much higher. Climate change may be the cause.

I want to understand the overlap between physical health, mental health, and healthy aging and whether/how stress (behaviorally and biologically) may tie these concepts together.

Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

At almost midway through, the “Stoeplanten” (Pavement Plants) citizen science project has been very successful. This research was initiated by Nienke Beets, who while working for the Science Communication and Society research group and Hortus Botanicus, gave her contribution to the Stoeplanten proje…

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,…
