Opinion. A return to the wild: Root exudates and food security (Trends Plant Sci)

My dog is a fantastic companion, but it’s obvious he could never fend for himself; domestication has eliminated his ancestral survival skills. Likewise, most crop plants thrive under human care, but have lost many of the traits that would help them survive in harsh conditions. Preece and Peñuelas…

Successive passaging of plant associated microbiome reveals robust habitat and host genotype-dependent selection (PNAS)

Study of the plant microbiome can contribute to sustainable agricultural systems through improvements to plant health and nutrition. One goal has been to select and design microbiome communities for specific functions. In a recent article, Morella et al. have used an experimental evolution approach to…

Root development is maintained by specific bacteria-bacteria interactions (bioRxiv)

Understanding plant-microbe and microbe-microbe interactions is challening. Both kinds of interactions have significant impacts on plant health and nutritional uptake. Finkel et al. address how microbe-microbe interactions shape plant phenotypes by using the synthetic microbial community (SynCom) consisting…

Rhizosphere microbiota structure alters to enable wilt resistance in tomato (Nature Biotech. - $)

Plants are frequently attacked by pathogens, but the pathogen-resistance is often attributed to the host. While interactions between the plant and its microbiota are recognized for their role in plant growth, their role in pathogen resistance is unknown. Kwak et al. studied the effect of soil-borne pathogen Ralstonia…
