| 中文摘要: |
| Serratia symbiotica是一种蚜虫的重要共生细菌。其与宿主的互作可归为自由生活、兼性共生与专性共生3种模式，因此可作为研究细菌与昆虫互作进化机制的重要模型。本文总结了有关S. symbiotica的株系分化、生活方式、与宿主互作及其作用机制的研究进展。不同株系的S. symbiotica在基因组特征、宿主分布、传播方式及宿主影响上存在较大差异，这为理解昆虫共生菌的多样性及其与宿主的共进化提供了新视角。 |
| 英文摘要: |
| Serratia symbiotica is an important symbiotic bacterium associated with aphids. Its interaction with hosts can be categorized into three modes: free-living, facultative symbiosis, and obligate symbiosis, making it a significant model for investigating the evolutionary mechanisms underlying bacterium-insect interactions. This article reviews recent research progress on strain differentiation, lifestyle characteristics, host interaction mechanisms, and functional roles of S. symbiotica. Significant variations exist among different strains in genomic features, host distribution patterns, transmission modes, and impact on hosts, offering novel perspectives for understanding the diversity of insect symbionts and their co-evolution with hosts. |
