An expression vector was constructed with a safe marker gene, 6-phosphomannose isomerase, and an insect-resistant gene, Galanthus nivalis agglutinin, was used in rice genetic transformation in the present study.

采用农杆菌介导法将来源于大肠杆菌的6-磷酸甘露糖异构酶安全选择标记基因和雪花莲凝集素抗虫基因构建于同一表达载体上进行遗传转化，获得带有安全标记基因的抗褐飞虱转基因植株。

To solve this problem of keeping date consistence in the heterochronous environment, the paper puts forward a synchronous updating system model, which applied Web Service to capture, store and then transfer updated things in the homogeneous distributed database system and farther implement the system's model of data synchronization, In the design of this model, the concurrency control of distributed things and the method of failure inspection are discussed and solved successfully.
