中文摘要:狼毒Stellera chamaejasme扩张已成为毒草型退化草原治理过程中一个不可忽视的问题，严重影响着草原的生态安全和畜牧业的可持续发展，当前关于狼毒在退化草原扩张机制方面的研究引起了国内学者的广泛关注。随着测序技术和生物信息学分析技术的快速发展，对狼毒相关微生物方面的研究不断深入，并揭示出狼毒与土壤微生物以及与自身内生菌之间的相互作用是其在退化草原成功扩张的重要机制之一。该文对狼毒相关土壤微生物和内生菌生态学方面的研究进展进行综述，并对微生物在狼毒的种间竞争、凋落物分解、植物-土壤反馈作用过程中的潜在作用进行探讨，最后对利用宏组学技术开展狼毒功能菌群挖掘与利用的前景进行展望，以期从植物-微生物互作角度了解这种重要毒害草的扩张机制，为挖掘狼毒微生物资源和开发狼毒生态防控新方法提供参考依据。

Abstract:The expansion of Stellera chamaejasme has become a significant issue in the management of degraded grasslands dominated by poisonous weeds, which poses a serious threat to the ecological security of grassland and the sustainable development of animal husbandry. Current research on the mechanism of expansion of S. chamaejasme in degraded grassland has attracted widespread attention among domestic scholars. With the rapid development of sequencing technology and bioinformatic analysis, the application of high-throughput sequencing technology over the past decade has significantly advanced microorganism-associated research on S. chamaejasme. Exploring the interactions between S. chamaejasme and soil microorganisms, as well as with its own endophytes, has become a crucial aspect for revealing its successful expansion. In this paper, the research progress in the ecology of S. chamaejasme-associated soil microorganisms and endophytes were reviewed, with an aim to understand the importance of plant-microbe interactions in this important poisonous weed. This paper also suggested the potential role of microorganisms in interspecific competition, litter decomposition, and plant-soil feedback processes of S. chamaejasme, and discusses the prospects of using metagenomic techniques to explore and utilize the functional microbiota of S. chamaejasme. Such work can provide a theoretical basis for the exploration of S. chamaejasme microbial resources and development of new approaches for ecological control of S. chamaejasme.
