 | | For 28 genera, including all genera (except Hesperomeles) and major generic segregates of Maloideae, we obtained about 7500 bp of sequences from four chloroplast DNA regions: the atpB-rbcL intergenic spacer, trnK intron plus matK gene, trnT-L-F region, and rps16 intron. |
 | | For outgroups we used Kageneckia, Lindleya, and Vauquelinia, the closest relatives of the traditionally circumscribed, pome-fruited subfamily. |
 | | The pattern of short internal branch lengths that we have reported for nuclear data also characterizes the most parsimonious cpDNA trees, frustrating efforts to understand higher-level relationships in the subfamily. |
