  • American ginseng (Panax quinquefolius L.) is grown in some regions of the USA and Canada and marketed for its health promoting attributes. While cultivation of this plant species has taken place in North America for over 100 years, there are many challenges that need to be addressed. In this article, the current production method used by growers is described and the challenges and opportunities for research on this valuable plant are discussed. These include studies on pharmacological activity, genetic diversity within the species, genetic improvement of currently grown plants, molecular characterization of gene expression, and management of diseases affecting plant productivity. The current research developments in these areas are reviewed and areas requiring further work are summarized. Additional research should shed light on the nature of the bioactive compounds and their clinical effects, and the molecular basis of active ingredient biosynthesis, and provide more uniform genetic material as well as improved plant growth, and potentially reduce losses due to pathogens.

  • 밭재배와 논재배처럼 토양환경이 상이한 조건에서 재배된 인삼의 지상부 생육의 경시적 변화 및 근부특성과 성분함량 차이를 비교하기 위해 금산지방의 직파재배 4년근 밭재배 및 논재배 농가포장을 선정하여 시험한 결과는 다음과 같다. 1. 논토양의 미사와 점토함량 그리고 토양수분과 공극율은 밭토양보다 뚜렸히 높았는데, 재배기간 동안의 토양수분함량 범위는 논재매 $17.5{\sim}19.5%$로 적당하였으나 밭재배는 $7.0{\sim}12.8%$로 낮은 수분함량을 보였으며, 논토양은 밭토양보다 인산과 칼슘함량이 적으나 염류농도와 유기물, 질산태질소, 칼륨, 마그네슘 함량이 높아 비교적 양호한 토양조건을 보인 관계로 초장, 생체근중 및 주당건물중 등 지상부와 지하부 생육은 논재배가 밭재배보다 양호한 생육을 보였다. 2. 논 밭재배간 순동화율 (NAR)과 작물생장율 (CGR) 직이 치밀하지 못했다는 Mog et al. (1981)의 보고와 비슷한 결과를 보였다. 표 5와 같이 생체근중의 분포비율은 직파 4년 재배에서 논 밭재배 모두 100 g 이상의 인삼은 생산되지 않았는데, 60 g 이상인 것의 비율이 논재배 5.3%로 밭재배 0.9%에 비해 많았으며 40 g 이상인 것의 비율도 논재배가 밭재배보다 높았다. 은 5월과 9월에 가장 뚜렸한 차이를 보였으며, 논재배시 근중은 9월 수확기에 가장 큰 증가를 보였으나 밭재배는 9 월에 조기낙엽 증가로 인하여 근중비대가 정지되어 뚜렸한 차이를 보였다. 3. 수삼수량은 논재배가 밭재배보다 약간 많으나 유의적인 차이는 없었으며, 적변 발생율도 논 밭재배간 유의적인 차이가 없었다. 4. 논 밭재배간 동체직경과 동체장, 뿌리의 수분함량 및 조사포닌과 50% 에탄올 추출 엑스함량은 유의적인 차이를 보였는데, 조사포닌과 엑스함량은 밭재배가 높았다. 5. 동체의 경도는 $5{\sim}8$월까지 논 밭재배 간에 서로 비슷하였으나 9월에 밭재배는 급격히 감소하여 뚜렸한 차이를 보였다.

  • Background: Wild ginseng, Panax ginseng Meyer, is an endangered species of medicinal plants. In the present study, we analyzed variations within the ribosomal DNA (rDNA) cluster to gain insight into the genetic diversity of the Oriental ginseng, P. ginseng, at artificial plant cultivation. Methods: The roots of wild P. ginseng plants were sampled from a nonprotected natural population of the Russian Far East. The slides were prepared from leaf tissues using the squash technique for cytogenetic analysis. The 18S rDNA sequences were cloned and sequenced. The distribution of nucleotide diversity, recombination events, and interspecific phylogenies for the total 18S rDNA sequence data set was also examined. Results: In mesophyll cells, mononucleolar nuclei were estimated to be dominant (75.7%), while the remaining nuclei contained two to four nucleoli. Among the analyzed 18S rDNA clones, 20% were identical to the 18S rDNA sequence of P. ginseng from Japan, and other clones differed in one to six substitutions. The nucleotide polymorphism was more expressed at the positions 440-640 bp, and distributed in variable regions, expansion segments, and conservative elements of core structure. The phylogenetic analysis confirmed conspecificity of ginseng plants cultivated in different regions, with two fixed mutations between P. ginseng and other species. Conclusion: This study identified the evidences of the intragenomic nucleotide polymorphism in the 18S rDNA sequences of P. ginseng. These data suggest that, in cultivated plants, the observed genome instability may influence the synthesis of biologically active compounds, which are widely used in traditional medicine.

  • Lime-bordeaux mixture (LBM) has been used instead of pesticides in ginseng field and orchard since the 1960's in Korea. In this experiment, LBM was made with different concentrations and sprayed in the field of ginseng for eco-friendly cultivation. Growth characteristics and disease such as alternaria blight, anthracnose, and gray mold were investigated in 4-5 year old ginseng after spraying LBM. LBM caused a little damage on leaf when it was sprayed at the time of leafing stage, late April and early May. Root weights of five-year-old ginseng were 43.1~51.5 g and 41.2~46.6 g in the plot of mid-April and mid-May treatments, respectively. These growth levels were further reduced as compared with that of the chemicals treatment plot. The rate of diseases in the plot of 6-6 and 8-8 ratio were 0.0~4.8% and 0.0~4.4%, respectively, which was similar with that in the plot of chemical control for alternaria blight and anthracnose. However, LBM had little effect on controling gray mold. It showed lower control effect in the plot of 4-4 ratio than that of chemical control. This result will be expected to be a useful guide that can be used in the field to the farmers of the ginseng.

  • Background: Panax ginseng, one of the valuable perennial medicinal plants, stores numerous pharmacological substrates in its storage roots. Given its perennial growth habit, organ regeneration occurs each year, and cambium stem cell activity is necessary for secondary growth and storage root formation. Cytokinin (CK) is a phytohormone involved in the maintenance of meristematic cells for the development of storage organs; however, its physiological role in storage-root secondary growth remains unknown. Methods: Exogenous CK was repeatedly applied to P. ginseng, and morphological and histological changes were observed. RNA-seq analysis was used to elucidate the transcriptional network of CK that regulates P. ginseng growth and development. The HISTIDINE KINASE 3 (PgHK3) and RESPONSE REGULATOR 2 (PgRR2) genes were cloned in P. ginseng and functionally analyzed in Arabidopsis as a two-component system involved in CK signaling. Results: Phenotypic and histological analyses showed that CK increased cambium activity and dormant axillary bud formation in P. ginseng, thus promoting storage-root secondary growth and bud formation. The evolutionarily conserved two-component signaling pathways in P. ginseng were sufficient to restore CK signaling in the Arabidopsis ahk2/3 double mutant and rescue its growth defects. Finally, RNA-seq analysis of CK-treated P. ginseng roots revealed that plant-type cell wall biogenesis-related genes are tightly connected with mitotic cell division, cytokinesis, and auxin signaling to regulate CK-mediated P. ginseng development. Conclusion: Overall, we identified the CK signaling-related two-component systems and their physiological role in P. ginseng. This scientific information has the potential to significantly improve the field-cultivation and biotechnology-based breeding of ginseng.

  • The abolishment of the red ginseng monopoly act by the Korean government in 1996 resulted in a drastic change in the Korean ginseng industry, leading to a significant increase in the market size and consumption of ginseng products. Red ginseng is most popular type, with approximately 74% of harvested fresh ginseng being processed into various red ginseng products. Since 1997, there has been a substantial increase in the cultivation of ginseng for production of red ginseng, which, in turn, has contributed to the proliferation of ginseng processing companies. To investigate the products of ginseng manufacturing businesses, we select 200 companies primarily engaged in ginseng processing or specializing solely in ginseng. Our survey on the status of ginseng industry covered 8 different categories. 1) Root ginseng: There were 66 companies involved in manufacturing red ginseng root, accounting for 33.0% of all surveyed companies. This was followed by black ginseng root with 36 companies (18.0%) and red ginseng fine roots with 22 companies (11%). 2) Red ginseng products: A total of 144 companies were involved in manufacturing red ginseng pouches, making it the most common product category. This was closely followed by 142 companies producing pure(100%) red ginseng extract concentrate. 3) Fermented red ginseng products: Companies producing fermented red ginseng extract concentrate products were the most numerous, totaling 26. Following this, companies producing fermented red ginseng stick and pouch products were next in line. 4) Ginseng products: There were 15 companies involved in the production of ginseng products, with the majority focusing on ginseng tea. 5) Black ginseng products: Companies producing black ginseng extract concentrate were the most numerous, with 31 companies, followed by 26 companies producing black ginseng extract pouches. 6) Taegeuk ginseng products: Only 5 companies were involved in the production of taegeuk ginseng products. 7) Fermented black ginseng, and 8) Ginseng berry products: These categories are manufactured by less than 5 companies each. However, the variety in ginseng berry products suggests the potential for future growth. In the 2000s, a trend emerged with the development of new processed products aimed at enhancing the functional components of red ginseng, and these products have captured the attention of consumers. However, this study primarily focuses on black ginseng, fermented red ginseng/fermented black ginseng, and ginseng berry products as they have exerted a significant influence on the overall ginseng industry.

  • 생물검정에 의한 유묘 이병율의 직접 조사치, 또는 근면 및 토양요인에 의한 이병율의 추정치를 이용하여 포장내에서의 년생별 지상부 결주율을 추정함으로써 토양에서의 인삼 뿌리썩음병 발병을 예측할 수 있는 시험 모형을 개발하였다. 그리고 발병예측 모형의 용인별 결주율 추정치와 포장에서 결주율 조사치간의 적합성을 통계분석을 통해 조사한 결과, 유묘 이병율에 의한 결주율 추정치는 근권요인(토양 이화학성 및미생물상 밀도)에 의한 추정치에 비해 결주율 조사치에 대한 적합성이 더 높았다. 조사 포장수를 확대하여 유묘이병율에 의한 발병예측 모형식의 적합성을 재확인한 결과, 저년생 인삼의 결주율 추정치는 3년생 포장, 그리고 고년생 인삼의 결주율 추정치는 5년생 포장에서의 실제 결주율 조사치와 1% 통계적 유의수준에서 일치하였다. 유묘 이병율에 의한 발병예측 모형식은 인삼 뿌리썩음병에 대한 토양 검정 차원에서 적용할 경우 재배예정지의 적지 여부를 판정할 수 있고, 인삼 생육기간 중에 적용할 경우 고년생 포장에서의 병진전을 예측할 수 있어 조기수확 여부를 판정할 수 있을 것으로 사료된다.
