Abstract

Geminivirus is a kind of single-stranded DNA virus. Experimental results from tomato golden mosaic virus (TGMV) showed that expression pattern of coat protein gene (cp) promoter was phloem specifically expressed. In this note, the studies on cp promoter of cotton leaf curl virus (CLCuV) which is found and identified recently suggest that the promoter is not phloem specifically expressed. The expressing activity of gus gene driven by the promoter exists not only in phloem but also in mesophyll tissues and root tip meristem. Transient expression suggests that cp promoter transactivated by AC2 shows expressing activity in mesophyll and vascular tissue of leaf vein.
