Initial sequencing of the internal transcribed spacer (ITS) region of this species generated unreadable sequences due to continual polymorphic positions. Cloning and sequencing the ITS region as well as sequencing the mitochondrially encoded cyt...
متن کاملGenotyping Phytophthora ramorum Isolates From Nurseries in the United States Using PCR- RFLP and Microsatellite Analyses
