  • Glucosinolates (GSLs), beneficial secondary metabolites for human health are abundantly present in radish vegetable. Radish is a member of Brassicaceae family and its seed, leaf and root contain very important GSLs. The objective of this study was to determine the variation of individual and total GSL contents in leaves and roots of 44 radish (Raphanus spp.) germplasm (26 R. sativus L., 3 R. raphanistrum, and 15 R. sativus L. var. raphanistroides Makino), and compare the GSL contents between leaves and roots among three Raphanus species. Thirteen GSLs were identified, being the glucoraphasatin (GRS) and glucobrassicin (GBS) the most abundant aliphatic and indolyl GSLs in both the leaves and roots. Variation in individual and total GSL contents was found among the germplasm of three Raphanus species. The GRS content was higher in roots than that of leaves in all three Raphanus species but the GBS content was higher in leaves than roots. GRS was represented 87.0%, 92.7% and 94.7% of the total GSL in roots of R. sativus L., R. raphanistrum and R. sativus L. var. raphanistroides (Makino) germplasm, respectively. Germplasm of R. raphanistrum exhibited the highest (average, $79.5{\mu}mol/g\;dw$) total GSL with a ranged from 62.7 to $92.9{\mu}mol/g\;dw$. The germplasm IT119288, Joseonmu and IT119262 from R. sativus L., RA 504 and K046542 from R. raphanistrum, and Gyeongju-2003-32 (G2003-32) and IT302373 from R. sativus L. var. raphanistroides (Makino) had high total GSL contents and these could be good candidates for developing the functional compounds-rich varieties in radish breeding program.

  • 무(Raphanus sativus L.)는 세계적으로 중요한 작물 중의 하나이다. 십자화과 식물 종자 생산에서 원하지 않은 내교잡에 의한 종자 결실로 오염이 발생하므로 씨의 순수성 검증은 매우 중요하다. 재배종 진주 대평 무(R. sativus cv. Daepeng)와 백자 무(R. sativus cv. Backza)의 교잡 분석을 실시하였다. 알로자임으로 상업적으로 이용되는 잡종 제1세대($F_1$) 무에 있어서 씨의 순수성을 평가하였다. 웅성과 자성 양친 360개체에 27개 대립유전자좌위를 조사하였다. 특히 Par-1 ($aa{\times}bb$), Lap-1($aa{\times}bb$), Est-1 ($aa{\times}bb$)에서 명확한 잡종 밴드를 나타내었다. Est-1 대립유전자좌위에서 자성 배우체로부터 기원된 것이 15개체(8.3%)가 발견되었고, 웅성 배우체로부터 기원된 것이 26개체(14.4%)가 발견되었다. 또한 다양도 측면에서 양친 계통에 비해 잡종 계통에서 높은 유전적 다양도를 유지하고 있었다. 샤논의 정보지수(Shannon's index)를 이용한 표현형 다양도는 교잡 계통이 가장 높았다. 알로자임에 의한 무 계통의 교잡에 의한 종자 생성에서 씨에 대한 순수성 검증이 효과적으로 탐지되어 육종 연구에 기여할 수 있을 것으로 판단된다.

  • Raphanus sativus L. has been reported to have anti-inflammatory and anti-tumor activity. However, the anti-inflammatory effect and mechanism of action of the Raphanus sativus L. seeds (RSS) with or without oil are still unknown. This study was undertaken to investigate the in-vitro anti-inflammatory effect with or without oil in the RSS on RAW 264.7 cells stimulated by lipopolysaccharide (LPS). Results showed the suppressed LPS-induced secretion of pro-inflammatory mediators such as nitric oxide (NO), inflammatory cytokine (IL-6, TNF-α). Additionally, a decrease in protein expression of iNOS was observed, but nuclear translocation of NF-κB p65 was not inhibited. To elucidate the underlying mechanism of the anti-inflammatory effect of RSS, the involvement of mitogen-activated protein kinase (MAPK) signaling pathways was examined. We also found that RSS blocked LPS-induced phosphorylation of c-Jun N-terminal kinase/stress-activated protein kinase (JNK) signaling but did not affect the phosphorylation of p38 MAPK and extracellular signal-regulated kinase (ERK) 1/2. These results suggest that RSS may have potential as an anti-inflammatory agent through the inhibition of LPS-induced inflammatory cytokine production via regulation of the JNK pathway.

  • To isolate antifungal substances from Korean radish (Raphanus Sativus L.) seeds, various purification techniques such as DE52 cellulose anion exchange, SP-Sephadex C-25 cation exchange, and Sephadex G-50 gel filtration chromatographies were used. The molecular masses of two purified R. sativus antifungal proteins (RAPs) were estimated to be about 6.1 kDa (RAP-1) and 6.2 kDa (RAP-2) by SDS-PAGE, and 5.8 kDa(RAP-1) and 6.2 kDa (RAP-2 by a gel filtration chromatography, respectively. Purified proteins RAP-1 and 2 clearly exhibited different growth inhibitory activities against other microorganisms like Candida albicans and Saccharomyces cerevisiae. Although they have similar molecular masses, both RAP-1 and 2 proteins are not identical because their microbial inhibitory actions were different. Therefore, RAP-1 could be a new antifungal protein when compared with the antifungal activities of 2S albumins, Rs-AFPs, Mj-AMPs, chitinase, glucanase, permatin, and ribosome inactivating proteins, all of which are anifungal proteins of plants.

  • The uranium removal capacity of radish sprouts (Raphanus sativus L.) in groundwater was calculated on the basis of the amount of uranium accumulated in the radish sprouts rather than the concentration in solution, of which process was very limited in previous studies. Continuous rhizofiltration clean-up system was designed to investigate the feasibility of radish sprouts, applying for uranium contaminated groundwater (U concentration: 110 μg/L) taken at Bugogdong, Busan. Six acrylic boxes (10 cm × 30 cm × 10 cm) were connected in a direct series for the continuous rhizofiltration system and 200 g of radish sprouts cultivars was placed in each box. The groundwater was flushed through the system for 48 hours at the constant rate of 5 mL/min. The rhizofiltration system was operated in the phytotron, of which conditions were at 25℃ temperature, 70% of relative humidity, 4,000 Lux illumination (16 hours/day) and 600 mg/L of CO2 concentration. While 14.4 L of contaminated groundwater was treated, the uranium removal efficiency of the radish sprouts (1,200 g in wet weight) was 77.2% and their removal capacities ranged at 152.1 μg/g-239.7 μg/g (the average: 210.8 μg/g), suggesting that the radish sprouts belong to the group of hyper-accumulation species. After the experiment, the sum of U amounts accumulated in radish sprouts and remained in groundwater was 1,472.2 μg and the uranium recovery ratio of this rhizofiltration experiment was 92.9%. From the results, it was investigated that the radish sprouts can remove large amounts of uranium from contaminated groundwater in a short time (few days) because the fast growth rate and the high U accumulation adsorption capacity.

  • Effects of triacontanol(TRIA) on several parameters of senescence including the changes of related enzyme activities were investigated in radish(Raphanus sativus L._ cotyledons developing in light. In senescing radish cotyledons, 1.0mg TRIA/1 retarded the degradation of chlorophyll content. Moreover, it depressed the increases of malondialdehyde and H2O2 contents compared to the control. Catalase and superoxide dismutase activities were highly maintained but the increase of peroxidase activity was inhibited remarkably under the TRIA application. These results suggested that TRIA participated in the regulation of senescence during the late part of cotyledon development where it delayed senescence through its action on free radical-associated enzymes and consequent metabolic turnover.
