Highly supported leaf-to-leaf HGTs are consistent with sequence similarity. We present a case study of a leaf-to-leaf HGT between the donor Rp3 (orange) and recipient Rm1 (green). (a) The inferred HGT from Rp3 to Rm1 in the spike gene has a support of 1000, shown on a subtree of the full species tree. (b) Sequence similarity of the donor Rp3 to its sibling GX2013 (purple) and the recipient Rm1. Rp3 and GX2013 are highly similar throughout the length of the genome, and Rm1 is more divergent throughout but equally similar in the spike region. (c) Sequence similarity of the recipient Rm1 to its sibling HuB2013 (blue) and the donor Rp3. Rm1 and HuB2013 are highly similar throughout the length of the genome except in the spike region, where Rm1 has received genetic material from Rp3. Thus, Rp3 and Rm1 are more similar in the spike region.
