The impact of arbuscular mycorrhizal fungi and endophytic bacteria on peanuts under the combined pollution of cadmium and microplastics
Researchers tested whether beneficial soil fungi and bacteria could help peanut plants cope with combined contamination from cadmium and microplastics. They found that the microbial treatment effectively trapped cadmium in the plant roots, preventing it from moving into the shoots and edible parts. The study suggests that harnessing natural soil microbes could be a practical strategy for growing safer food in polluted farmland.

This review examines how rhizosphere bioengineering — manipulating plant-microbe interactions — can promote plant growth and soil health under climate change conditions including elevated temperature, drought, and pollution stressors such as microplastics.
The Effect of Native Plant Diversity on the Success of Invasive Species in Polluted Soils
Researchers assessed the resistance of native plant communities to invasive species under soil pollutant stress by establishing experimental communities of varying species diversity, each paired with a distinct invasive species, and measuring growth traits and soil properties. Results indicated that soil pollution can weaken native plant communities and create competitive advantages for invasive species, with community diversity modulating resistance outcomes.
