摘　　要：The diseased sample G7 was collected from Ageratum plants showing yellow vein symptoms in Xialian,Nanning,Guangxi province and tested with primers specific for DNA-A of several geminiviruses by polymerase chain reaction.The results showed that mixed infection of begomoviruses appeared in G7 sample.Partial DNA-A sequence comparison with other geminiviruses showed that G7 sample was infected by 5 dif-ferent begomoviruses,they were Papaya leaf curl China virus(PaLCuCNV),Ageratum yellow vein China virus(AYVCNV),Tomato leaf curl China virus(ToLCCNV),Euphorbia leaf curl virus(EuLCV) and Tobacco leaf curl Yunnan virus(TbLCYNV).The diseased sample G7 was collected from Ageratum plants showing yellow vein symptoms in Xialian, Nanning,Guangxi province and tested with primers specific for DNA-A of several geminiviruses by polymerase chain reaction. The results showed that mixed infection of begomoviruses appeared in G7 sample. Partial DNA-A sequence comparison with other geminiviruses showed that G7 sample was infected by 5 different begomoviruses, they were Papaya leaf curl China virus （ PaLCuCNV）, Ageratum yellow vein China virus （ AYVCNV ）, Tomato leaf curl China virus （ ToLCCNV ）, Euphorbia leaf curl virus （ EuLCV ） and Tobacco leaf curl Yunnan virus （TbLCYNV）.
