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 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.

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.

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.

De missie van het Plant Sciences onderzoeksprogramma is om bij te dragen aan de duurzame productie van gewassen van hoge kwaliteit, bloemen en hoogwaardige producten met een biologische basis. Dit wordt gerealiseerd door het opdoen van fundamentele kennis over biologische processen omtrent de ontwikkeling…

Maak een reis door de geschiedenis en de toekomst van het leven op aarde.

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,…

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

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.

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…

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.

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.

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…

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

Op zijn sterfbed vertelt Ali nog één laatste keer over zijn leven.

What are trait-trait relationships in wetlands? To what extent the so-called leaf economics traits deviate from terrestrial ecosystems? How traits specific to wetland plant relate to plant strategies? What’s the relationship between wetland plant traits to the ecosystem functioning (e.g. productivity,…

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

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).

Plants, are sessile organisms, have developed strategies to adapt to changes in their environment, in part by altering their growth and development.

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

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