Bamboo products are considered to be resource-efficient and sustainable. Cups, plates, cutlery, crockery or drinking straws are already made from the plant's woody stem axes or fibers and are available on the market. Especially in view of the forthcoming Europe-wide ban on disposable plastics, alternatives to conventional plastics are becoming more and more important. "From a health risk point of view, however, these products are not always suitable for use as tableware," warns Andreas Hensel, President of the Federal Institute for Risk Assessment (BfR).

There are many environmental factors like drought and overfertilization that put plants under stress. In such cases, a complex signalling cascade is triggered inside the plant. This stress management apparatus works the same for all land plants - in moss just as in rye. An international research team led by the Hebrew University of Jerusalem, in which the University of Göttingen participated, wanted to know exactly how stress management works. The scientists therefore focused on a specific gene for the receptor in this signalling cascade.

The industry is relying more and more on natural substances and, with this, satisfying consumer demand for more biobased and sustainably produced products. Plant-based products and ingredients are particularly in demand in the cosmetics industry. Through a new strategic partnership with the French company Plant Advanced Technologies (PAT), the Swiss chemical group Clariant intends to expand its involvement in this business field.

On average, each German buys around 60 items of clothing a year - not counting underwear. Conventional production of one kilogram of cotton consumes up to 10,000 liters of water. The high water consumption is one of many reasons why the textile industry is considering a recycling economy. So far, however, with the exception of some synthetic fibers, textiles have been based exclusively on virgin fibers.

Carbon dioxide is rarely readily available in water. Some aquatic plants therefore find it difficult to meet their carbon requirements by photosynthesis using carbon dioxide - the normal method for land plants. They use hydrogen carbonate as a supplement or alternative for the photosynthesis reaction. Ecologists at the University of Duisburg-Essen have now discovered that the distribution of these two plant groups is changing in favor of hydrogen carbonate users.

All organisms that have been genetically modified fall under the regulations for genetically modified organisms (GMOs) in the European Union, according to the ruling of the European Court of Justice in 2018. This sounds plausible at first glance, but it is not that simple, as the Max Planck Society has already pointed out.

The bacterium Escherichia coli is one of the favourite organisms of microbiologists and biotechnologists. E. coli is easy to cultivate in the laboratory. It has been well researched and is well suited for the implementation of biotechnological processes. So far, however, the bacterium has used carbohydrates as a source of carbon both in nature and in industrial applications. An international research team led by the Weizman Institute in Israel has now succeeded in converting the diet of E. coli to carbon dioxide from the air.

A fragrance wafts over the sweet potato field. What for us smells like a herbal balm is an alarm bell for the tuber plant, as researchers at the Max Planck Institute for Chemical Ecology (MPI) have now discovered. In the "Scientific Reports" of the Nature group, the team reports on the function of this variety-specific defense mechanism.

Astin is a herbal agent to which healing powers are attributed - not least in the fight against cancer. One source of this medicinal substance is Aster tataricus, also known as Tatarinow's aster. This medicinal plant, which is native to the higher altitudes of Asia, is used primarily in traditional Chinese medicine. A research team from the University of Tübingen and the Technical University of Dresden has now succeeded in isolating astins from the plant, cultivating them and producing them in larger quantities using biotechnology.

Red, pink, pink or white: the poinsettia is the most popular indoor plant in Germany second only to the orchid, even though Euphorbia pulcherrima is mainly used for Christmas decorations in this country. According to the marketing initiative of the European poinsettia breeders, Stars for Europe, around 32 million specimens are sold in Germany every year. More than 700 plant nurseries produce poinsettias in this country.
