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.
