Micro-organisms living inside plant roots team up to boost the plant’s growth and tolerance to stress. This research is featured this week in the scientific journal Science.

A hyperparasitoid is a parasitoid whose host is also a parasitoid. NIOO-researcher Martine Kos and her former colleague Roxina Soler have been doing research into ways to protect crops against these harmful insects.

If you’re small, smells are a good way to stand out. A team of researchers led by the Netherlands Institute of Ecology (NIOO-KNAW) has demonstrated for the first time that two different types of micro-organisms – bacteria and fungi – use fragrances, known as terpenes, to hold conversations. And that’s not all. “We actually believe that terpenes are the most popular chemical medium on our planet to communicate through.”

When it comes to their role in aquatic ecosystems, exotic water plants are generally no different than indigenous species. In fact, they can be an asset, argues Bart Grutters (NIOO-KNAW) in his PhD thesis. That doesn't mean all exotic species should be given free rein. But they can be managed more effectively if you focus on their properties and not their place of origin.

Sorghum is the fifth most important cereal in the world. In sub-Saharan Africa, many farmers rely on this grain for food and feed. But Striga, a parasitic weed, can have a devastating impact on crop yield. With an 8-million-dollar grant from the Bill & Melinda Gates Foundation, an international team will now explore the potential of soil microbes to offer crop protection. The Netherlands Institute of Ecology (NIOO-KNAW) is coordinating this 5-year project.

Tiny predators in the soil can literally sniff out their prey: soil bacteria, which communicate with each other using scent. A team of researchers from the Netherlands Institute of Ecology (NIOO-KNAW) has discovered that these predators - called protists - 'eavesdrop' on the bacteria's communication. It's a discovery that opens up perspectives for agriculture. The results are available online this month in The ISME Journal, from the publishers of Nature.

Zonder gezonde, biodiverse bodem geen gezonde samenleving. Maar hoe vertaal je dat in goed beleid?

A team of ecologists and microbiologists that includes NIOO's Paul Bodelier has identified a unique organism in samples from a Romanian cave nicknamed 'Stinky Mountain'. The novel bacteria can grow on methane, an important greenhouse gas that contributes to global warming.
