Neighbor-joining (NJ) tree obtained with Rubus GBSSI-1 exon sequence and corresponding published GBSSI-1 and GBSSI-2 sequences from Rosaceae subfamilies, rooted with Pisum and Rhamnus sequences. Brackets on right delimit groups of paralogous sequences, GBSSI-1 and GBSSI-2. Short vertical lines (A and B) indicate a second duplication of the GBSSI gene occurring in some species of subfamily Maloideae. Rubus sequences obtained in this study are underlined in grey. Bootstrap values obtained from 1000 replicates are shown under the branches
