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

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.

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…

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,…

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…

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

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

Bepaalt de verspreiding van bodemschimmels zeldzaamheid van sommige planten?

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

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 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.

In dit interdisciplinaire project worden data science technieken toegepast om de interactie tussen de Universiteit en stad Leiden (Town&Gown) kwalitatief en kwantitatief zichtbaar te maken vanaf 1575. Een van de mogelijke invalshoeken voor vervolgonderzoek is diversiteit, met name vanuit de internationale…

What is vegetation structure and composition in SFM primary forest, secondary logged over forest (logging FSC certified and logging non certified) in comparison to primary forest? What is avian guild diversity in SFM primary forest, secondary logged over forest (logging FSC certified and logging non…

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.

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.

1: What is the relative importance of alfa and beta biodiversity in polar ecosystems, and how does intraspecific variation influence this? 2: How can we use remote sensing to determine functional biodiversity (within communities) in polar ecosystems? 3: Temporal and spatial scales of functional biodiversity:…

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

De Universiteit Leiden heeft het initiatief genomen voor een landelijk overleg van universitaire Diversity Officers. Doel is uitwisseling van kennis van en ervaring met de opzet en uitvoer van diversiteitsbeleid.

Voor het Leidse citizen scienceproject Oeverplanten onderzoeken buurtbewoners, wetenschappers en studenten de oevers van Leiden. Welke plantensoorten komen op welke plekken voor? En hoe kan de Gemeente Leiden de oevers beter beheren voor een optimale biodiversiteit?

Oogst na oogst binnenhalen van rijstveld, zonder nieuwe rijstplanten te zetten? Door een ontdekking komt dit scenario misschien wel dichterbij. Leidse wetenschappers hebben een gen ontdekt waarmee ze eenjarige planten na het bloeien opnieuw laten groeien, in plaats van dat de planten sterven. Publicatie…
