Figure 2

A phylogenetic tree of DNA helicase of putative autonomous helitrons of maize and other species. The phylogenetic tree was constructed by the neighbor-joining method using MEGA4 software [32] with 1,000 bootstrap replicates, the bootstrap scores < 50% were deleted. The accession numbers and names of the putative helicases of other species were abbreviated as shown in Figure 1, with the addition of the following: Bo, Brassica oleracea (ABD65117); Mt, Medicago trunculata (ABE82731) [10].
