URP primers that were derived from repetitive DNA sequence of rice weedy rice have been applied for producing PCR polymorphisms in different fungal species. URP-PCR protocol employed stringent PCR with high annealing temperature over $55^{\circ}C$ throughout the thermo-cycling reaction, giving high reproducibility. Under the PCR condition, Each single URP primer produced characteristic fingerprints from diverse genomes of different fungal species, indicating its universal applicability. URP-PCR has been accessed for applicability to various fungal species with 33 genus, 142 species and 1,489 isolates. Numerous related papers have demonstrated that URP-PCR profiles of fungal species are very useful for identifying fungal species at intra and inter species levels. The results were reviewed in this paper.

Genetic variation of Perilla germplasms was investigated using RAPD markers. Forty-two Perilla frutescens lines and cultivars collected form locals were subjected to RAPD analysis using 220 primers. Among them only 13 primers showed polymorphic bands and these 13 primers provided a total of 144 bands, consist of 115 polymorphic and 29 monomorphic ones. The polymorphic bands were subjected to phylogenetic analysis using UPGMA and maximum parsimony (MP) methods. In the UPGMA method, similarity coefficiency of 42 Perilla frutescens lines and cultivars ranged from 0 to 0.7842. The dendrogram of 42 lines and cultivars obtained through UPGMA method resulted in two major groups, and the similar clustering pattern was found by MP method, suggesting Perilla germplasms utilized in this study truly can be divided into two major groups. Although the two major groups were consistent roughly with their phenotypes (under of node, weight of 1,000 grains, and oil content), in detail, much inconsistency also was present.
