Graphical abstract in Guo et al. (2025): "Model illustrating how dense planting triggers plant-soil feedback to enhance maize resistance. High-density planting increases canopy linalool, which activates systemic jasmonic acid (JA) signaling and HDMBOA-Glc exudation from roots. These exudates selectively enrich rhizosphere bacteria that induce salicylic acid (SA) signaling, thereby enhancing maize resistance. This defense-promoting feedback comes at a cost to maize growth. Some components of this figure were created by BioRender.com."

![Graphical abstract Wang et al. (2025): "The concept of plant-soil feedback is widely applied in natural ecosystems in investigations of plant community dynamics. Crop rotation was developed to counteract negative plant-soil feedback caused by host-specific pathogens and nutrient shortage of crops grown in monoculture. Subsequently, a combination of technological developments and ecological principles have transformed the traditional, pathogen-focused approach of crop rotation into a broader synthesis for promoting soil health and ecosystem function. In the figure, “αA” and “βB” represent the plant-soil feedback effects of soil that has been conditioned by plant A and B on their own growth, respectively; “αB” and “βA” represent the reciprocal plant-soil feedback effects of soil conditioned by plants A and B, respectively. The sum of these feedback effects (αA − αB − βA + βB) indicates the magnitude and direction of the pairwise feedback.
