한국산 흰명아주(Chenopodium album var. album), 명아주(var. centrorubrum), 가는명아주(var. stenophyllum)를 대상으로 aceto-orcein에 의한 염색체 수와 모양을 조사하였고, 45S rDNA 유전자를 이용한 FISH (fluorescence in situ hybridization) 방법을 수행하여 세포유전학적 유연관계를 고찰하였다. 체세포 염색체 수는 흰명아주와 명아주는 모두 2n = 6x = 54개인 반면에 가는명아주는 2n = 4x = 36으로 뚜렷이 구별되었으며, 기본염색체수는 x = 9 개였다. 명아주속의 염색체에서 45S rDNA의 위치를 알아보기 위한 FISH 결과는 흰명아주의 경우 8개의 signal이, 가는명아주에서는 2개의 signal이 관찰되어 종간 차이를 보였으며, 모두 염색체 말단부위에서 관찰되었다. 염색체의 수와 형태, 45S rDNA를 이용한 FISH 결과는 명아주가 흰명아주에 통합되지만, 가는명아주와는 뚜렷이 구별됨을 지지해 주었다.

An antiviral protein (CAP30) with ribosome-inactivating activity was purified from the leaves of Chenopodium album L. through ammonium sulfate precipitation and column chromatography using S-Sepharose, Blue-Sepharose, FPLC Suprose12 HR, and FPLC Mono-S. The molecular wight of CAP30 was estimated to be 30kD. CAP30 was thermostable, maintaing its activity even after incubation at $70^{\circ}C$ for 30 min, and was stable in the pH range of 6 to 9. In a cell-free in vitro translation system using rabbit reticulocyte lysate, protein synthesis was inhibited by the addition of CAP30 with an $IC_{50}$ of 2.26pM. The comparison of N-terminal amino acid sequences of this protein with known ribosome-inactivating proteins (RIPs) revealed that it had some sequence homology with PAP-S and PAP-R from pokeweed (Phytolacca americana)and dodecandrin from P. dodecandra, but had no sequence homology with RIPs from other plants belonging to different orders. The mosaic symptoms on tobacco leaves caused by cucumber mosaic virus infection was completely inhibited by 100 ng/ml of the pure CAP30 protein.

본 연구에서는 참마와 명아주의 항산화 및 항염증 효능을 평가하기 위해 참마와 명아주 에탄올 추출물을 이용하여 free radical 소거활성, enzyme-linked immunosorbent assay (ELISA) 실험을 수행하였다. 참마와 명아주 추출물의 free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) 소거활성($EC_{50}$)에서 각각 2.386, 0.524 mg/mL로 측정되었다. 또한 참마와 명아주 추출물의 혼합 시료의 free radical 소거활성은 참마 추출물:명아주 추출물 비율이 2:1일 때 가장 뛰어난 것으로 나타났다. IL-6와 $TNF-{\alpha}$의 ELISA 실험을 통해 항염증효능을 평가한 결과, 마우스 비장세포에서 IL-6의 경우 1 mg/mL 농도에서 참마 추출물은 대조군과 대비하여 27.17% IL-6 생성을 감소시켰으며, 명아주 추출물은 72.30%의 감소를 나타내었다. $TNF-{\alpha}$의 경우 참마 추출물은 61.97%, 명아주 추출물은 77.85%로 유의성 있는 $TNF-{\alpha}$생성 감소 효능을 나타내었다. 이 결과들을 통하여 참마와 명아주 추출물은 항산화, 항염증 효능을 가지고 있으며, 이를 활용하여 항염증에 효과가 있는 천연물 제제에 응용 가능성이 있음을 확인하였다.

Seed dormancy behavior of weed seeds is a critical determinant of their survival rates in a given cropping system as it helps the weeds to evade herbicides and other weeding practices. We investigated the effects of red light, alternating temperature, stratification duration and different doses of nitrogen containing compounds alone or in combination with red light on breaking seed dormancy of Chenopodium album L. The application of red light(80 ${\mu}mols^{-1}m^{-2}$) significantly increased seed germination of C. album in all treatments. Germination rates of 12 h incubated seeds were highest under 20 min of red light irradiation than 1 min, 5 min and 10 min treated seeds. Germination rate was significantly higher at alternating temperatures of $25^{\circ}C\;and\;5^{\circ}C$ for 12 h each with an irradiation of red light(80 ${\mu}mols^{-1}m^{-2}$) for 10 min than other treatments. Stratification period of 15 days significantly stimulated germination percentage of seeds incubated in dark, although 5 days of stratification along with red light application for 10 minutes exhibit similar effects on seeds. Seed germination was also enhanced by nitrogen containing compounds like $NaNO_2,\;KNO_3,\;NH_4Cl\;and\;NH_4NO_3$. We observed that seed germination increased significantly with 25 mM $KNO_3$ and 10 mM $NH_4NO_3$ in dark condition, while $NaNO_2$ and $NH_4Cl$ enhanced seed germination under red light irradiation. It was concluded that red light alone or synergized with alternating temperatures, stratification and nitrogen compounds, especially nitrite and ammonium enhanced seed germination of C. album. Thus, the red light can play a vital role in present and future weed management strategies.

The antiviral activity of CAP30 from Chenopodium album, a type1 ribosome-inactivating protein (RIP), was examined against 5 different plant viral pathogens, and its activity against Tobacco mosaic virus was compared to those of well known antiviral proteins such as Pokeweed Antiviral protein from leaves and seeds. When the inoculating concentration of Tobacco mosaic virus was varied from 0.4 to $400{\mu}g/ml$, it was observed that CAP30 at the concentration of $1{\mu}g/ml$ suppressed the viral infection of C. amaranthicolor and C. quinoa almost completely up to $40{\mu}g/ml$ Tobacco mosaic virus. Results from the assays for the inhibitions of in vitro translation of rabbit reticulocyte lysate and the suppression of Tobacco mosaic virus infection ($10{\mu}g/ml$) to C. quinoa indicated that CAP30 is a strong inhibitor of protein synthesis and virus infection. The infection of several viruses other than Tobacco mosaic virus to host plants were also inhibited by $5{\mu}g/ml$ CAP30, suggesting that a gene encoding CAP30 can be used to develop transgenic virus-resistant plants.

2005년 11월부터 2006년 11월까지 총 4회에 걸쳐 독도의 유관속식물상을 조사하였다. 독도에서는 26과 44속 46종 1아종 1변종으로 총 48분류군이 확인되었는데, 이는 양치식물 1분류군, 쌍자엽식물 36분류군, 단자엽식물 11분류군으로 이루어져 있다. 식물구계학적 특정식물로는 V등급종인 초종용(Orobanche coerulescens Stephan)과 IV등급종인 왕호장근[Fallopia sachalinensis (F.Schmidt) RonseDecr.], 섬괴불나무(Lonicera insularis Nakai), 섬초롱꽃(Campanula takesimana Nakai), 왕김의털(Festuca rubra L.) 등 총 13분류군이 확인되었다. 식재된 종으로는 곰솔(Pinus thunbergii Parl.), 동백나무(Camellia japonica L,) 보리장나무(Elaeagnus glabra Thunb), 무궁화(Hibiscus syriacus L.) 등이 있다. 분류학적으로 실체가 의심되는 종(species)으로는 가는명아주(Chenopodium virgatum Thunb.), 돌피[Echinochlca crusgalli (L.) P.Beauv.]로써 각각 흰명아주(Chenopodium album L,), 물피[Echinochloa crusgalli var. oryzicola (Vasinger) Ohwi]와 구분되는 형질을 공유하거나 불분명하여 동정에 있어서 혼란이 야기된다. 종유입 방법별로는 풍산포(anemochore) 31분류군, 동물산포(zoochore) 8분류군, 해류산포 (hydrochore) 2분류군인 것으로 판단되며, 이외의 종들은 인위적 수단에 의하여 유입된 것으로 보인다.

In order to investigate the host range of the mosaic disease of black locust in the Chunchon area, the sap of the mosaic-diseased leaves of black locust itself and the cowpea leaves infected with the above mentioned sap, were inoculated to 53 species of plants belong to 12 families. As to the result, no difference in infection was found as related to the virus sources, and the infection was recognized in 4 species of the family Chenopodiaceae and 8 species of the family Leguminosae. The plants recognized as hosts are as follows: the plants which showed local infection are Chenopodium album, Ch. ambrosioides, Ch. quinoa; the plants which showed systemic infection are Chenopodium amaranticolor, Phaseolus vulgaris, Robinia pseudo-acacia, Vigna sinensis; and Astragalus sinicus, Melilotus indicus, Phaseolus angularis, Pisum sativum and Vicia faba were recognized as carriers. Through investigating its host ranges and symptoms, this mosaic virus of black locust seems not to be regarded as the group of the black locust mosaic virus in southeastern Europe reported by Milinko et al (1961). And, too, it is thought hardly to exist in combination with the cowpea mosaic virus. It appears, therefore, that this mosaic virus was confined to that of black locust.

This study was conducted to investigate the heavy metal accumulation in wild plants. The samples from 5 plant species on 14 sites were taken on the roadside where urban and industrial regions in northern Gyeonggi do. Artemisia princeps var. orientalis, Chenopodium album L. var. centrobrum, Erigeron canadensis L., Rumex crispus L. and Taraxacum platycapum H. Dahlst were taken from different parts of the plants gathered in surveyed sites for analysing. This study classified which species were suitable to accumulators, excluders, or indicators which were provided as Phytoremediation for heavy metals(Cd, Cr, Ni, Pb and Zn) and considered the applicability of that work. 1. The mean accumulation of 6 heavy metals in plants was as follows; Zn> Cu> Cr> Pb> Ni> Cd in rows except for Ni and Pb in Erigeron. 2. The highest heavy metal accumulators were Taraxacum and Artemisia. 3. The comparison of heavy metal accumulations between the tops and roots in the plants was as follows; Zn> Cd> Pb> Ni> Cu> Cr. 4. Comparison of heavy metal accumulations between tops and roots, root parts were higher than the top parts in most of the plants. Especially, in Taraxacum, a ratio was over 1.0 in Cr, Ni, and Zn. Therefore, Taraxacum was an accumulator for 3 heavy metals. And Erigeron, Chenopodium, Rumex, Artemisia were good for excluders which had lower than 1.0.
