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.

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

The Women, Peace and Security (WPS) agenda arising from United Nations Security Council Resolution 1325 has reached a critical juncture in its short 20-year history. Despite comprising ten resolutions designed to bolster the agenda and expand its scope and normative power, serious challenges to the…

Tom Buitelaar assesses how 'agency' is addressed in peacekeeping studies and identifies gaps.

The availability of complete plant genome sequences together with the ever increasing amount of data on the molecular, cellular and physiological mechanisms of plant development require mathematical and computational models to obtain a complete overview of and generate new insights into the quantitative…

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.

In this article, Jasmijn Boeken, explores in which ways the defining characteristics of the different zones can be found in the digital sphere.

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.

The Peace Run was held in The Hague on 14 September as part of the Just Peace festival. The event aimed to gather funds for UNICEF the Netherlands. A large team from Leiden University took part in the Run. Altogether a successful day!

Plastics have become an integral part of modern society due to their versatility and durability.

Leiden University has locations in both Leiden and The Hague.

Who doesn’t want peace? Yet we don’t always appreciate how fragile it really is. This is why Leiden University was a co-organiser of the Just Peace Festival from 21 to 25 September 2016.

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

The goal of the Kenniswerkplaats Diversiteit is to answer research questions schools in the Hague have in collaboration with the schools. The aim is to offer all children the same opportunities to develop through education.

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

Leiden University’s Campus the Hague is soon to expand into the Central Innovation District in the centre of The Hague. Plans are under way for a Campus boulevard with a new University building in the area between the Prins Bernhardviaduct and Schedeldoekshaven.

International Coalitions for Peace in the Era of Decolonization, 1918-1970

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.

How is it possible that people kill each other? And above all: how is it possible that people who are able to peacefully live with each other at one moment, can kill each other at another one?

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.
