摘　　要：综述了近１０年来杆状病毒基因的调控研究进展，包括６种与调控有关的基因及１１种晚期表达因子基因的功能．杆状病毒基因组中的同源区为其顺式作用元件（ｃｉｓ－ａｃｔｉｎｇｅｌｅｍｅｎｔ）或增强子，对基因的表达起正调作用，而病毒编码的反式激活因子（ｔｒａｎｓａｃｔｉｖａｔｏｒ）则决定着病毒基因表达的调控以级联方式进行．The present paper reports about the regulation of baculovirus over the past ten years. It has been found that the homologous regions in the genome of baculovirus are its cisacting element or enhancer whose function is positive regulation; while the transactivator which is encoded by virus decides that baculovirus genes are transcribed in a regulated cascade. Six genes related to the regulation and 11 genes of expression factors in late phase are reported respectively.
