摘要: A Begomovirus isolate JH1 was obtained from Crassocephalum crepidioides showing yellow vein symptoms in Jinghong of Yunnan province, China. The complete sequence of Begomovirus DNA-A-like molecule of JH1 was determined to be 2745 nucleotides long. When compared with other begomoviruses, JH1 DNA-A has the highest nucleotide sequence identity (86.4%) with that of Tobacco curly shoot virus. Comparisons of individual encoded proteins with other begomoviruses show that different parts of JH1 DNA-A have different ancestors. The molecular data show that JH1 is a distinct Begomovirus species, for which the name Crassocephalum yellow vein virus is proposed.
