Abstract
As a result of surveys of okra begomoviruses (genus Begomovirus, family Geminiviridae) conducted over the last five years in Central Brazil, we report the complete genome sequence of an isolate of okra mottle virus (OMoV). The DNA-A and DNA-B components were 2660 and 2653 nucleotides (nt) long, respectively, and they were most closely related to the DNA-A (~99 % nt identity) and DNA-B (~98 % nt identity) components of an OMoV isolate from a soybean plant. A phylogenetic tree was generated based on these sequences, and it was shown that both of the OMoV DNA components were grouped in a branch with Brazilian begomoviruses known to infect weeds. By recombination analysis, strong evidence was observed that the OMoV genome may have been the product of a double inter-species recombination event.
