Cenchrus pauciflorus, native to the Americas, has rapidly spread across northern China since its introduction in the late 20th century, invading ecologically fragile regions such as the Horqin Sandy Land, the Liaohe River Basin, and the Inner Mongolian grasslands, where it has become a major invasive species threatening the ecological security of sandy grasslands and agro-pastoral ecotones. The burrs of C. pauciflorus are armed with retrorse bristles that readily attach to dispersal vectors, facilitating long-distance dispersal. Coupled with its high tolerance to adverse conditions such as drought, nutrient-poor soils, and saline-alkaline environments, these traits have laid the foundation for its successful invasion. This review systematically summarizes recent research progress on C. pauciflorus from four perspectives: reproductive strategies, responses abiotic stress, allelopathic inhibition, and interactions with rhizosphere microorganisms. It further elucidates the multidimensional adaptive mechanisms and ecological effects underlying its invasion. Based on this synthesis, current research limitations and future research directions are proposed to deepen the understanding of invasion ecology and provide a scientific basis for the management and control of C. pauciflorus. keywords:Cenchrus pauciflorus  reproductive strategy  abiotic stress responses  rhizosphere micro-bial interactions  invasive species View Full Text  View/Add Comment  Download reader
