The Sundanese people, the largest ethnic group in West Java, have been using traditional medicine for a long time. Known as ubar kampung, Sundanese indigenous knowledge, beliefs and practices of traditional medicine are based on local people’s knowledge and use of Medicinal, Aromatic, and Cosmetic (MAC)…

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

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

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,…

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

Hoe kan de methode om de gecombineerde effecten van metaal-gebaseerde chemische stoffetn te bepalen worden verbeterd?

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.

Less than 1 in 10 drug candidates that enter phase 1 clinical trials actually gets approved for human use.

This thesis presents the systematics, epidermal defense, and bioprospecting of wild orchids.

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

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

The RNA guided endonuclease based on the CRISPR/Cas system of Streptococcus pyogenus is a potent new tool for genome engineering in plants.

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

Increasing the efficiency of gene targeting (GT) as a genome editing tool in plants has been an important goal in plant biotechnology.

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.

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

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…
