| 摘 要： | 通过农杆菌介导的转基因烟草研究表明，棉花曲叶病毒外壳蛋白基因启动子驱动的ＵＧＳ基因表达活性不仅存在于韧皮部，而且出现在叶肉组织和根尖分生组织中，基因抢轰击的瞬时表达研究表明，ＡＣ２激活后的ＣＰ启动子在叶肉及叶脉均有表达活性，暗示该启动子为近组成型的启动子。

| Abstract: | The promoter fragment of coat protein gene(CP) from cotton leaf curl virus w as f used to the GUS reporter gene and transferred to tobacco by Agrobacterium-med iat ed transformation to test promoter expression. Results showed that CP prom oter w as active not only in phloem, but also in mesophyll and root tip meristem. Trans ient expression by particle bombardment demonstrated that activated CP promo ter by AC2 was active in both leaf vein and mesophyll, suggesting that CPpromot er was a near constitutive promoter. |
