Genetic variation in chloroplast and nuclear ribosomal DNA in Utah juniper (Juniperus osteosperma, Cupressaceae): Evidence for interspecific gene flow
Terry RG, Nowak RS, Tausch RJ. 2000. Genetic variation in chloroplast and nuclear ribosomal DNA in Utah juniper (Juniperus osteosperma, Cupressaceae): Evidence for interspecific gene flow. American Journal of Botany. 87(2):250-258
Geographic patterns of genetic variation in chloroplast (cpDNA) and nuclear ribosomal (nrDNA) DNA were examined to test the hypothesis of hybridization between Juniperus osteosperma and Juniperus occidentalis in the Great Basin of western Nevada. Genetic relationships based on DNA sequences and geographic patterns of genetic variation in chloroplast and nrDNA are consistent with morphology in suggesting interspecific gene flow between J. occidentalis and J. osteosperma.
