Phylogenetic relationship between the GGERV10 elements. Based on the LTR sequence, neighbor-joining phylogenetic tree of full-length GGERV10 elements was constructed. Evolutionary distances were constructed using the Kimura 2-parameter method [38]. The result of bootstrap calculations (bootstrap value >70%) based on 1,000 replications is shown. The black bar indicates 0.005 nucleotide substitutions per nucleotide position
