Dialogue instead of a chemical maze – new strategy for sustainable crop protection

Climate change creates stress. This provides an opportunity for pests to exploit plant weaknesses and reproduce. For the infested plant, this can be catastrophic and often fatal. But instead of continuing to protect harvest yields with toxic substances as before, the transnational DialogProTec project is now taking a completely new approach: researchers want to intervene in the communication between plants and pests to keep them healthy.

In conjunction with reference laboratories of the World Health Organization WHO medtech company Curetis AG is developing new technologies and products that identify the pathogens of infectious diseases such as tuberculosis and their resistance. The solutions are impressive.

A plant hormone and growth in the dark

All multicellular organisms including plants produce hormones. One of the hormones plants produce is the phytohormone jasmonic acid which has for a long time mainly been known as a second messenger substance that is released when plants are attacked by pathogens. Some years ago Dr. Michael Riemann from the Karlsruhe Institute of Technology KIT discovered that jasmonic acid acts as a major growth regulator of phytochrome-mediated responses in…

Keeping an eye on reed decline

The reed zones around Europes lakes are becoming increasingly smaller. The biologist Dr. Jan Nechwatal at the University of Constance is investigating the causes of reed decline and has identified a previously unknown plant pest.

Phosphorus recovery from sewage sludge - 21/10/2020

Bacteria help to recycle phosphorus

Biotechnology for the bioeconomy: in something known as the P-bac process, sulphur bacteria extract phosphorus from sewage sludge ash. Phosphorus is one of the key building blocks of life and an essential nutrient for plant growth. When there is not enough phosphorus in the soil, farmers apply it via organic or mineral fertilisers.

New biomaterials developed at the University of Bayreuth eliminate risk of infection and facilitate healing processes. These nanostructured materials are based on spider silk proteins. They prevent colonization by bacteria and fungi, but at the same time proactively assist in the regeneration of human tissue. They are therefore ideal for implants, wound dressings, prostheses, contact lenses, and other everyday aids.

Cells to analyse air

Exhaust gases smoke generated by industry and private household combustion processes every day we inhale a mixture of a broad range of particulate matter potentially resulting in respiratory tract or cardiovascular diseases. Dr. Silvia Diabat and her team from the Karlsruhe Institute of Technology KIT are examining the molecular mechanisms triggered by flue ash and other nanoparticles in the cells of the lung tissue.

Marja Timmermans: Humboldt Professor with a penchant for small RNAs

Molecular biologist Marja Timmermans has found out how plant cells can communicate with each other using mobile ribonucleic acid molecules. The use of small RNAs (sRNA) is a fundamental principle that applies not only to plant cells, but also to animal and human cells. These days, Timmermans' laboratory methods are used around the world. She has recently been awarded Germany’s most highly endowed international research award - the Alexander…

Scientists to combat antibiotic-resistant bacteria in wastewater

In Germany, around 1,500 tonnes of antibiotics per year are administered to humans and animals. As a result, more and more bacteria are developing resistance to common antibiotics. As part of HyReKA, a cooperative project funded by the BMBF, scientists led by Professor Thomas Schwartz from the KIT are investigating how antibiotic-resistant pathogens spread and how they can be prevented from doing so.

Bioanalysis techniques for the characterization of biological material

Science constantly provides researchers with new challenges biologists and bioanalysts have to deal with and which come from sources as varied as the ever increasing number of resistant pathogenic bacterial strains or the famine conditions in Third-World countries. In the search for scientific truths bioanalysis is the development optimization and application of the entire range of analytical methods available. However we need to keep in mind…

David Schleheck exploring the effective degradation of surfactants

David Schleheck biologist at the University of Konstanz focuses on the bacterial degradation of surfactants and LAS in particular. The results of his research are of huge importance for the recycling of grey water in areas including home sewage treatment systems for example.

Fungi an introduction

After animals and plants fungi are the third largest kingdom of eukaryotic organisms. Most people see them as plants because they typically grow in soil and do not move around like animals in the search for food supermarkets sell edible mushrooms such as white mushrooms and shiitake. But no fungi are capable of carrying out photosynthesis themselves the fungal energy metabolism is driven by organic molecules of dead and sometimes also living…

A study also involving researchers from Constance shows that marine seaweed releases huge quantities of iodine when exposed to stress. This process contributes to cloud formation and thus has an effect on the climate.

Hunters of lost treasures

On 1st December 2008 Prof. Dr. Karl Schmid the first person to hold the F.W. Schnell Foundations endowed professorship for crop biodiversity and breeding informatics started the ball rolling on a unique European-wide project. Schmid and his colleagues are searching gigantic databases in which genetic analyses and plant descriptions are stored for hidden treasures.
