Effect of Low-Density Polyethylene Microplastics on Incidence of Cotton Verticillium Wilt and the Structure and Function of Rhizosphere Microbial Community

Microplastics have become a global environmental concern, but the impact of microplastics on plant disease remains poorly understood. The primary objective of this study was to evaluate the effects of low-density polyethylene (LDPE) microplastics on cotton Verticillium wilt (CVW), as well as the structure and function of the soil microbial community. Metagenomic sequencing was performed to characterize the microbial community composition of the cotton rhizosphere. The experiment consisted of five treatments: a control group, and four LDPE groups with concentrations set at 0.1
