A total of 61 recombinants from nine putative recombination events were detected with RDP3, especially the breakpoints of six events which have both two parental sequences that can be determined precisely with Simplot. To our knowledge, 53 recombinants were found for the first time. Our study also suggests that a relatively high recombination frequency occurs in the PreC/C gene region and the position near gene boundaries.展开更多
