What are the genes and molecular mechanisms involved in bacteria-mediated plant drought tolerance?

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.

- How to deconvolute metabolic mixture of precursors and products by biontransformation? - How to optimize the reaction conditions to produce bioactive compounds in biotransformation? - What is the effect of co-treating fungi or bacteria for biotransformations?

The application of compliance archaeology techniques such as mechanical large scale excavations where large quantities of data are gathered in relatively little time (and relatively inexpensively) and a firm post-excavation research phase yielded a whole new body of archaeological evidence.

New insights into the Fayum Epipalaeolithic and Neolithic.

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.

Basketry, cordage and textiles made of plant fibers or bark are rarely preserved in the archaeological record. By means of experimental archaeology and microwear analysis, we obtain indirect evidence about this important craft.

Tracking early human behaviour through plant processing and -exploitation.

In our lives we often have little attention or appreciation for plants, let alone the ones we commonly call weeds. This inattention for plants has been described as plant blindness. The Stoepplantjes project aspires to decrease plant blindness by changing the image of weeds and using citizen science.…

The mission of the Plant Sciences cluster is to contribute to the sustainable production of high-quality crops, flowers and high-value bio-based products, and to contribute to the maintenance and restoration of biodiversity in natural ecosystems. This is realised by generating fundamental knowledge…

We examine how soil-derived legacy effects of plants structure natural ecosystems, determine aboveground plant insect interactions, and how we can use soil legacy effects to restore degraded ecosystems.

Throughout history, a large portion of the world's population has lived under imperial rule. Although scholars do not always agree on when and where the roots of imperialism lie, most would agree that imperial configurations have affected human history so profoundly that the legacy of ancient empires…

This book is the first comprehensive presentation of the archaeology of Syria from the end of the Paleolithic period to 300 BC.

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…

Plant Sciences' contribution to the Bioactive Molecules research theme is to identify new plant bioactive molecules, and unravel their mechanisms of action in plant development or health, and the regulatory networks and (bio)synthetic pathways required for their production.
