Neighbor-joining (NJ) tree based on amino acid sequences of Adh loci from diverse plant taxa. ADH sequences in Rosaceae are highlighted in blue. Numbers above the branches or near the branch nodes indicate bootstrap values (1000 replicates). GenBank accession numbers are in brackets. Multiple intra-individual clones for Adh1 (Adh1-1 and Adh1-2) and Adh2 (Adh2-1 and Adh2-2) are differentiated by the number in the parenthesis following the taxa name. *: Though Adh2-1 was not obtained by G-PCR in Malus, its transcription was detected by RT-PCR in 'Fuji' (M. domestica).
