| 摘 要： | 致病杆菌是与斯氏线虫共生的肠杆菌科细菌,存在于昆虫病原线虫肠道内,可随线虫的侵染进入寄主昆虫血腔,迅速繁殖并产生多种代谢产物,抑制其他杂菌的污染,保护线虫繁殖的环境。多年研究发现,该菌的代谢产物具有广泛的杀虫、抑菌、抗癌等生物活性。本文介绍了致病杆菌外膜蛋白基因、菌毛蛋白基因、共生作用相关基因、溶血素相关基因、杀虫毒素蛋白基因、抗生素相关基因以及专利申请基因的研究进展。

| Abstract: | Xenorhabdus are Gram-negative bacteria that live in symbiosis with Steinernema nematodes. During recent decades, more and more researches are focused on the molecular biology of these bacteria. This paper reviews the advances in some functional genes of Xenorhabdus, including outer member protein genes, mobility protein genes, symbiosis-associated genes, insecticidal toxin protein genes, hemolysin genes, antibiotics-related genes, and some patented genes. |
