참다래 육종을 위한 종 분류와 분자 표지인자로서 유용하게 이용될 수 있는 primer를 개발하기 위하여 참다래 genome 특이 반복 염기서열로부터 19∼20base 크기로 18개의 primer를 제작하여 kiwifruit target primer(KT primer)라 명명하였으며, 동아시아 지역에서 수집된 7종 22계통의 다래나무 속 식물을 이용하여 활용 가능성 을 조사하였다. 유연관계 분석을 위하여 7개의 primer가 선발되었으며, 이를 이용한 RAPD 결과 크게 2개의 군으로 나뉘어 졌다. 제 1 군(A. arguta, A. melanandra, A. kolumikta와 A. marcrosperma)은 주로 과실에 전혀 털이 없으며 잎에는 털이 전혀 없거나 어렸을 때 극소량의 연모가 있다가 없어지는 그룹으로서 Leiocarpae 절에 속하였다. 제 2 군(A. chinensis, A. deliciosa 및 A. eriantha)은 어린 과실에서는 털이 많았다가 성숙하면서 털이 없어지는 계통 및 잎과 줄기에 털이 아주 많거나 조밀한 솜털이 있는 그룹으로서 Stellatae절에 속하였다. 제 2 군은 Stellatae 절에서도 Pefectae 아절에 속하는 것으로 A. chinensis, A. deliciosa 및 A. eriantha가 포함되었으며, 다시 A. chinensis와 A. deliciosa를 포함하는 그룹과 A. eriantha 등 2개의 그룹으로 나뉘어졌다. 같은 부모로부터 유래된 것으로 알려진 A. chinensis와 A. deliciosa는 80％의 유사도에서 두 개의 그룹으로 나뉘어졌다. 또한 PCR 결과 A. deliciosa 종 및 헤이워드와 토무리 계통 특이 밴드가 KT12F와 KT6F에서 나타났으며, 유전양상 분석에서 KT7F와 KT12F가 유용하였다. 본 연구 결과 KT primer는 참다래의 유전양상 분석과 특이한 유전양상을 나타내는 개체선발 및 도태에 유용하게 이용될 수 있고, 또한 참다래 육종 효율향상에 많은 도움을 줄 수 있다고 판단되었다.

AFLP(Amplified Fragment Length Polymorphism) analysis was conducted to cultivars of tobacco, Nicotiana tabacum in order to select the cultivar-specific markers. AFLP results using 12 primer sets revealed genetic diversity among 12 field grown tobacco cultivars. Polymorphic fragments amplified by PCR was purified and cloned to identify their nucleotide sequences. From the sequences of them, 40 primer sets were designed to select cultivar-specific markers. When genomic DNA isolated from tobacco were used as PCR template, a set of primers, BrSF/BrSR showed Burley-specific band patterns. The results indicate that AFLP technique used in this experiments is useful for identifying tobacco cultivars in a rapid manner.

A large number of individual ginseng plants have been selected in the farmer's fields to develop new ginseng varieties with desirable traits since 1970s. Among them, Hwangsukjong with green stem and yellow berry was selected as a ginseng germplasm. The phenotype of Hwangsukjong is quite different from Jakyungjong that has violet stem and red berry and has been cultivated in most of ginseng fields. Therefore, Hwangsukjong was crossed with Jakyungjong to clarify the inheritance of stem color and then the characteristics of $F_1\;and\;F_2$ hybrids were investigated. $F_1$ hybrid plants were similar to Jakyungjong in most of aerial part characters and showed hybrid vigor in fresh weight of root and weight of 100 seeds. In $F_2$ generation, the stem color was segregated in a ratio of 3 violet to 1 green. From this result, it was elucidated that violet color was controlled by single dominant gene. In another experiment, DNA was extracted from parents (Jakyungjong and Hwangsukjong) and $F_1$ hybrid. For each primer evaluated, multiple band profile was produced comprising from one to five major bands plus a varying number of minor bands and amplified bands were detected among most primers. In case of UBC primer number 13, 17, 30, 31, and 43, band patterns of parents and $F_1$ hybrid were very similar, but the others were not. Especially, in {\sharp}1$, {\sharp}4$, and {\sharp}33$, specific band was produced in Hwangsukjong and $F_1$ hybrid while in {\sharp}6$, another specific band was produced in Jakyungjong and $F_1$ hybrid. Therefore, $F_1$ hybrid had all specific bands at these primers. So, these selective markers could be used for identification of characteristics of $F_2$ hybrids

The Korean ginseng, Panax ginseng C. A. Meyer is a popular medicinal herb in Araliaceae. Genetic map in crops provides valuable information for breeding, genetic and genomic researches. However, little information is available for construction of genetic map in ginseng. Up to now, we have produced large amounts of expressed sequence tags (ESTs) from four ginseng cultivars (37Mb, 49Mb, 39Mb, 47Mb from Gopoong, Gumpoong, Chunpoong and Yunpoong respectively using pyrosequencing technique and 5Mb from normalized full-length cDNA library of Chunpoong) to obtain comprehensive information of gene expression, and constructed EST database including ESTs from public database. Till now, we designed 261 SSR primer sets using EST sequences and identified 106 intergenic polymorphic markers. And 44 of the 106 showed polymorphisms among panax ginseng cultivars. Among 44 markers, 27 SSR polymorphic markers were inspected to 51 $F_2$ population from Yunpoong x Chunpoong, which showed good at the fitness of Mendellian segregation ratio 1:2:1. To enrich the number of markers, and thus construct high resolution genetic map which can be used as frame map for further genome sequencing. we are planning to develop large scale EST-derived SNP markers which are available in the F2 population. This study provides genetic information as well as foundation for ginseng researches such as genetics, genomics, breeding, and the final goal for whole genome sequencing.
