In order to estimate the relationships among four taxa (Styrax japonicus, Styrax obassia, Styrax shiraianus and Pterostyrax hispidus) of two genus in the Styracaceae and their regional populations, RAPDs analysis was performed. Fifteen random primers generating 238 RAPD bands were enough to reveal differences in genotype bands. They were clustered into three groups by the UPGMA phenogram. The first group was Styrax japonicus populations, the second group was consisted of Styrax obassia populations and S. shiraianus populations, and third group was Pterostyrax hispidus population. The UPGMA phenogram based on RAPD analyses showed that Styrax obassia and S. shiraianus had the closest relationship among four taxa. Species as well as genera of the Korean Styracaceae were well discriminated by the RAPD analyses.

Styrax japonicus is a deciduous shrub or a small tree belonging to the family Styracaceae. Since 1990, a rust fungus has continuously been found on S. japonicus leaves across the country. The morphological characteristics of the rust fungus were most consistent with those of Pucciniastrum styracinum reported on Styrax obassia in Japan. The species identification was confirmed by molecular phylogenetic analysis of the internal transcribed spacer and large subunit rDNA sequences. The current study provides mycological information with morphological measurements and molecular phylogenetic data of P. styracinum found on S. japonicus in Korea. Therefore, this is the first confirmed report on the presence of P. styracinum on S. japonicus in Korea.
