| Abstract: | We report eight variable dinucleotide microsatellite loci cloned from flowering dogwood (Cornus florida L.) using a biotin enrichment protocol. Degenerate oligonucleotide primer‐polymerase chain reaction (DOP‐PCR) was used to generate a population of DNA fragments, from which adenine‐cytosine dinucleotide (AC) and adenine‐guanine dinucleotide (AG) repeats were captured using biotinylated probes and streptavidin coated magnetic particles. The captured fragments were cloned into plasmids, and the plasmid library was screened for microsatellites using a simple PCR technique. Selected plasmids were sequenced, and PCR primers were designed and optimized using a thermal‐gradient thermocycler. The loci reported are highly variable with an average of 9.25 allele per locus and an average heterozygosity of 0.84. |
