Phylogenetic trees of several MuLE elements. A, Phylogenetic tree of MuLE elements in rice (MoOS-521, MoOS-J1, and RMu1-IR136), maize (Trap, MuDR, and Jittery), and Arabidopsis (Far1). The tree is derived from parsimony analysis of amino acids from the conserved transposase domain (see Fig. 6) of these sequences. All nodes of this tree had bootstrap values of 100 with the exception of that leading to MoOS-J1 and Jittery, which had a bootstrap value of 85. The numbers refer to the branches. 1, MuDR; 2, Trap; and 3, Jittery. B, A phylogenetic tree of the TIRs of several distinct MuLE elements. Bootstrap values are as indicated at the nodes. Nodes without values ascribed had a value of 100.
