| Abstract: | In 2005, Eclipta prostrata plants exhibiting yellow vein symptoms were observed in Guangzhou, Guangdong province, China. A virus isolate G8 was cloned from a symptomatic plant. The complete nucleotide sequence of G8 DNA-A was determined to be 2745 nucleotides, which had typical characteristics of Begomovirus genome organization. The comparison of complete nucleotide sequence of DNA-A showed that isolate G8 shared the highest sequence identity with Alternanthera yellow vein virus (AlYVV) isolates G38 and Hn51 at 95.9% and 94.3%, respectively. These results show that G8 infecting E. prostrata in Guangdong is a strain of AlYVV. |
