Background : Cucuma longa L., in the family Zingiberaceae, is distributed in tropical and/or sub-tropical regions mainly in India and China. This species is commonly called tumeric, powder is used as medicinal herbs and/or flavor enhancer. It has been cultivated in southern region mainly Jindo. However, it might be possible to extend cultivation region due to rise in average temperature. In order to select superior lines, agronomic characteristics is commonly used. Because this is not the ultimate solution, the DNA marker approach has benefited the modern plant breeding. Therefore an easy approach by using one kind of primer have been developed from random amplification of polymorphic DNA sequences (RAPD) to discriminate effectively between different cultivars of Cucuma species Methods and Results : DNAs were extracted from the harvested roots of Cucuma sp. using DNeasy plant Mini kit (Qiagen, Hilen, Germany). These plants cultivated from GARES (Hamyang) and used for PCR amplification. The relative concentration of the extracted DNA was estimated Nano Drop ND-1000 (NanoDrop Technologies, Wklmington, De, USA) and final DNA concentration was adjusted to 5.5 ng/㎕. In this study 9 primer pairs were tested on 8 Cucuma sp. These primers showed polymorphism in Cucuma sp. The cluster dendogram showed that the similarity coefficients ranged from 0.68 to 0.87, CUR02 turned out to be CUR11, and CUR16 is similar to CUR17. Conclusion : These finding could be used for further research on cultivar development by using molecular breeding techniques and for conservation of the genetic diversity of Cucuma species. These data on polymorphism difference based on RAPD will be give us invaluable breeding information by selection of superior lines.

Background : Cudrania tricuspidata Bureau is a widely used medicinal perennial woody plant. Obtaining information about the genetic diversity of plant populations is highly important for conservation and germplasm utilization. In this study, we developed single nucleotide polymorphism (SNP) markers derived from chloroplast genomic sequences to identify distinct Korean-specific ecotypes of C. tricuspidata via amplification refractory mutation system (ARMS)-PCR analyses. We performed molecular authentication of twelve C. tricuspidata ecotypes from different regions using DNA sequences in the chloroplast TrnL-F intergenic region. Methods and Results : SNPs were identified based on the results of nucleotide sequence for the intergenic region of TrnL-TrnF gene (chloroplast). Molecular markers were designed for those SNPs with additional mutations on the second base from SNPs for amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). HRM pattern analyses were performed using the Mx3005P QPCR System (Agilent Technologies, CA, USA). Conclusion : We collected 12 individual lines of C. tricuspidata from various region in South Korea and China. Based on the nucleotide sequence in the trnL-trnF intergenic region of these lines, six SNPs and a deletion of 12 bps were identified and 12 individual lines were able to be grouped in one Korean ecotype and two different ecotypes of chinese lines, chinese line 1 and 2. The SNP markers developed in this study are useful for rapidly identifying these specific C. tricuspidata ecotypes collected from different regions.
