Unrooted phylogenetic tree of acyl-ACP TEs showing Subfamilies A to J. Those branches falling outside the shaded areas are non-grouped and therefore are not part of any subfamily. Bootstrap values are shown at each subfamily node. Asterisks denote approximate locations of characterized sequences. A detailed tree for each individual subfamily can be found in Additional files 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, Figures A1-A10.
