Molecular classification of wild roses using organelle DNA probes

Abstract

Chloroplast and mitochondrial DNA probes were used to deduce molecular systematics of 17 wild rose species by restriction fragment length polymorphism. Phylogenetic trees divided these genotypes into two to three groups of cytoplasmic relatedness depending upon the probe. The data indicated differential maternal inheritance of mitochondrial and chloroplast DNA in rose. The species forming a clade on phylogenetic trees also differed from one another phenotypically and belonged to different sections.
