• Disrupting cell-cell communication to suppress virulence in the bacterium Bacillus cereus

    A major public health goal is to identify new strategies for fighting microbes. In Bacillus cereus, a human pathogen, the expression of virulence genes is synchronised and results from communication among bacteria. In a recent study, INRA researchers and Israeli scientists collaborated to develop synthetic peptides capable of interfering with this process. Published on August 14, 2018, in Chemical Communications, the results of this work should lead to novel methods for countering the virulence of bacterial pathogens.

Semi-natural habitats help keep pests and weeds in check

Conserving semi-natural habitats such as forests, hedges and semi-natural permanent grasslands can be beneficial to the natural enemies of crop pests and weeds, and thus help farmers indirectly. A large international consortium involving INRA researchers (1) has shown that when it comes to landscape composition and the affect it has on the natural regulation of pests and predators, responses vary widely. The studies also showed that landscape alone is not in itself an efficient means to regulate crop pests.

A brain mechanism involved in mediated learning is identified

Researchers from INRA and INSERM have just identified the brain mechanism involved in the mediated learning process. Their results, published online on 30 August 2018 in Neuron, show that cannabinoid receptors in the hippocampus play a key role in establishing these types of associations.

A unique database providing information to quantify the adaptive capacity of beech to climate changeExplainer Buy Footwear Shoe amp; Clarks Store Shoes Online 7SwR7gq

Researchers at INRA and the University of Helsinki1 have worked together to release a unique database to the scientific community2. Assembling data collected under the auspices of an EU Cost Action, the database BeechCOSTe52 gathers over 860,000 measurements of phenotypic traits. These data, from more than 500,000 beech trees growing in plantations located in 38 European countries, cover the entire range of beech’s distribution. Over 15 years of work have gone into producing the database; a vital resource for analyzing and understanding the beech’s adaptive capacity to climate change and the potential effects of climate on its distribution range.
