Mitochondrial DNA Diversity in Oat Cultivars and Species

Electrophoretic gel patterns of endonuclease restriction digests of mitochondria! DNA (mtDNA) isolated from oat ( Arena sativa L.) cultivars and other Avena spp. were examined for banding pattern differences indicative of cytoplasmic diversity. A knowledge of oat cytoplasmic diversity would he useful for assessing vulnerability of cultivars to pathogens, for elucidating phylogenetic relationships among Avena spp., and in testing for …
