High-resolution quantification of root dynamics in split-nutrient rhizoslides reveals rapid and strong proliferation of maize roots in response to local high nitrogen

Patches rich in nitrogen are rapidly colonized by selective root growth in maize, which was quantified at high time resolution with state-of-the-art non-invasive imaging techniques in a paper-based growth syste

Plant community stability is associated with a decoupling of prokaryote and fungal soil networks

Abstract Soil microbial networks play a crucial role in plant community stability. However, we lack knowledge on the network topologies associated with stability and the pathways shaping these networks. In a 13-year mesocosm experiment, we determined links between plant community stability and soil microbial networks. We found that plant communities on soil abandoned from agricultural practices 60 years prior to the experiment promoted destabilising properties and were associated with coupled prokaryote and fungal soil networks. This coupling was mediated by strong interactions of plants and microbiota with soil resource cycling. Conversely, plant communities on natural grassland soil exhibited a high stability, which was associated with decoupled prokaryote and fungal soil networks. This decoupling was mediated by a large variety of past plant community pathways shaping especially fungal networks. We conclude that plant community stability is associated with a decoupling of prokaryote and fungal soil networks and mediated by plant-soil interactions

Dataset and R wokflow used in the manuscript "Between vs. within-species variation in plant-soil feedback relates to different functional traits, but exudate variability is involved at both scales"

Here we provide the experimental data and the R workflow used to obtain the results presented in the manuscript "Between vs. within-species variation in plant-soil feedback relates to different functional traits, but exudate variability is involved at both scales". We investigated the relationship between plant-soil feedback (PSF) and several plant functional traits encompassing various aspects of growth, root properties and root exudate variability. The investigation was conducted at two diversity scales: between-species (12 species) and within-species (20 Festuca rubra genotypes). We found that the traits associated with PSF variation substantially differed between interspecific and intraspecific levels, but root exudation was involved at both scales
