Haplotyping of Cornus florida and C. kousa chloroplasts: Insights into species-level differences and patterns of plastic DNA variation in cultivars.

ABSTRACT: Chloroplast DNA is a part of plant non-nuclear genome, and is of particular interest for lineage studies. Moreover, the non-coding regions of cpDNA display higher mutation rates than the conserved coding cpDNA, which has been employed for phylogenetic and population research. We analyzed the cpDNA of 332 gDNA samples from collections of Cornus florida and C. kousa (commercial cultivars, breeding selections, and wild kousa accessions from Asia), using the chlorotyping system developed on North America-native, wild accessions of C. florida. Our results indicated significant differences in chlorotype frequencies between the two species. Cornus florida samples were represented by all major chlorotypes previously described, whereas all C. kousa samples analyzed had only one of the chlorotype pa
