DNA samples of oaks from the collection at the University of California, Davis Arboretum have been isolated, and partial sequences determined for genes of ribulosebisphosphate carboxylase large subunit and for internal transcribed sequences of ribosomal RNA genes. A comparison of these sequences contributes to an elucidation of the phylogeny of this important plant genus. The agreement between the patterns with rbcL and ITS sequences strengthens considerably the conclusion that these molecular data can reveal the actual pattern of evolutionary relationships among the Quercus species.
