The so-called heterosis effect is not only well-known among plant breeders, but also very popular. It describes the fact that a crossbreed of two maize inbred lines provides a significantly higher yield than either of the two parent plants. However, until now it has been unclear which molecular mechanisms this effect is based on.
An estimated 300 soil researchers came together in Berlin for the BonaRes conference from February 26 to 28 to discuss their newest findings regarding the soil.
New concepts for the cultivation of food in urban environments are in demand to ensure food security for future generations. Under the umbrella term"urban farming", methods like aquaponics have proven to be a promising alternative. The combination of fish and plants, which use each other in a recirculation system to grow tomatoes and lettuce, not only saves arable land, but above all fertilizer and water. Fish excretion is processed into plant fertilizer by bacteria. In return, the hydroponic plants purify the water of the fish in the aquarium.
Globalization has many advantages for humans and technology. But for flora and fauna the mixing of native with foreign organisms can be dangerous. Because non-indigenous animal and plant species often have no natural enemies. Therefore, they spread unhindered and decimate the resources for native species.
The European Investment Bank (EIB) announced the launch of a new financing initiative that aims to unlock close to €1 billion of investment in the agriculture and bioeconomy sector. This large EIB lending programme for agriculture and bioeconomy outlines the Bank’s broader support for funding this sector. The operation will be guaranteed by the EU budget under the European Fund for Strategic Investments (EFSI), which forms a central part of the “Investment Plan for Europe” of the European Commission under the Juncker administration.
There are two sides to everything – even carbon dioxide (CO2): on the one hand the rapid increase in atmospheric CO2 concentration due to the burning of fossil fuels causes intensification of the greenhouse effect, which in turn fuels global warming. On the other hand, CO2 is essential to keep plants, algae and some bacteria alive: they convert the greenhouse gas into biomass in a process known as photosynthesis, in which CO2 and water are used to produce sugars and oxygen.
Two years ago Bayer, mostly known as a chemical and pharmaceutical company, announced their plans to take over the US-based agriculture specialist Monsanto. The future merger caused quite the stir from the get-go, as the resulting super agro-chemical company would be the largest worldwide. With a price tag of US$62.5 billion, the takeover would also be the largest one ever to be realized by a German company.
There are many reasons why insects are vanishing in alarming numbers. One reason is intensive farming and the corresponding use of synthetic crop protection agents and pesticides. For instance, the widespread use of the neonicotinoids has been shown to be hazardous to the health of bees and bumblebees.
An initial financing round helped the founders of ECF Farmsystems GmbH realize their idea of an aquaponics farm in Berlin in 2014. Since then, the start-up has been supported by co-founder and managing director Nicolas Leschke from the "IBB Beteiligungsgesellschaft mbH".
Better together – this applies in particular to many creatures that form symbioses with microbes in order to tap new food sources or protect their offspring. The same goes for the wool beetle Lagria villosa. This beetle is colonised by several strains of closely related Burkholderia gladioli bacteria, which protect the beetle's eggs from fungal attack.
