  • 본 실험은 양액의 종류와 배지의 종류, 그리고 양액의 농도가 20일 무의 생육과 몇가지 품질에 미치는 영향을 알아보고자 실시하였다. 20일 무의 양액재배시 적절한 양액의 구명을 위하여 기존의 Cooper, Hoagland, Yamazaki양액의 비교실험을 실시한 결과, YamaBaki양액이 엽장, 엽수, 지상부와 지하부 생체중 등 전반적으로 Hoagland와 Cooper 양액보다 좋은 결과를 나타내었다. 근형지수는 모든 처리구에서 약 0.66으로 비교적 낮은 수치를 보였다. 14가지 조합의 배지를 이용하여 고형배지경을 실시하였다. 그 결과 모래 배지가 가장 균일하고도 좋은 생육의 20일 무를 배출하였고, 피트모스는 반대의 생육을 보였다. 근형지수의 경우 전반적으로 고형배지경이 순수수경재배보다 높은 수치를 나타내었다. Yamazaki 양액의 적정농도 수준을 구명을 위하여 모래를 배지로 하여 20일 무의 생육과 품질을 비교 조사한 결과, 1.0mS/cm 이상의 농도에서는 전반적으로 20일 무의 생육이 좋았으며, 특히 1.5mS/cm가 가장 좋은 생육을 보였다. 비타민 C의 함량과 티오시아네이트 함량은 1.0mS/cm이상의 처리구에서는 현저한 차이가 없었으나, 0.5mS/cm는 상당히 높은 수치를 보였다. 또한 무기물 함량의 경우는 모든 처리구에서 통계적 유의성이 없었으나, 칼륨이 1.5mS/cm에서 비교적 높은 함량을 나타내었다.

  • In this study, we investigated the effects of the ethanol extract of aerial parts of Raphanus sativus L. (ERL) on breast cancer cell proliferation and gene expression associated with cell proliferation and apoptosis in MDA-MB-231 human breast cancer cells. The MDA-MB-231 cells were cultured in the presence or absence of various concentrations (100, 200, or 300 ${\mu}g$/mL) of ERL. ERL significantly decreased cell proliferation after 48 h of incubation (P < 0.05). The protein and mRNA expression of $ErbB_2$ were decreased significantly in a dose-dependent manner (P < 0.05). The protein expression of $ErbB_3$ was decreased significantly at an ERL concentration of 300 ${\mu}g$/mL (P < 0.05), and mRNA expression of $ErbB_3$ was decreased significantly in a dose-dependent manner (P < 0.05). The protein expression of Akt was decreased significantly at the ERL concentration of 200 ${\mu}g$/mL (P < 0.05), and the protein expression of pAkt was decreased significantly in a dose-dependent manner (P < 0.05). The mRNA expression of Akt was decreased significantly at the ERL concentration of 200 ${\mu}g$/mL ERL (P < 0.05). The protein and mRNA expression of Bax were increased significantly at ERL concentrations of 200 ${\mu}g$/mL or higher (P < 0.05). The protein expression of $Bcl_2$ was increased significantly at ERL concentrations of 100 ${\mu}g$/mL or higher (P < 0.05), and mRNA expression of $Bcl_2$ was increased significantly at an ERL concentration of 300 ${\mu}g$/mL (P < 0.05). In conclusion, we suggest that Raphanus sativus, L. inhibits cell proliferation via the ErbB-Akt pathway in MDA-MB-231 cells.

  • Two individuals of intergeneric hybrids in the crossing of Brassica pekinensis ♀$\times$Raphanus sativus ♂ were obtained, and among the three kinds of plants, Brassica, Raphanus, and F1, comparison on the mega- and microsporogenesis, megagammetophyte formation, and morphological changes in the developing sporangia, etc., were made. Differences between Brassica and Raphanus were observed in the shape of mega- and microsporangia, their changes in development, and the formation of megagametophyte. Sporangia of the F1 plants, until pre-meiotic stage, show intermediate, maternal, paternal, or vigorous inclination, and the difference of these characteristics when compared with those of the parent is slight. Meiotic irregularity resulted from the intergeneric hybridity of F1 plant gives rise to the abnormal mega- and microspore and accompanied abortive female and male gametophytes, bringing about the remarkable differences from its parent in the morphological changes of the developing mega- and microsporangia.

  • Three catalase cDNA clones were isolated from the small radish (Raphanus sativus L.). Their nucleotide and deduced amino acid sequences showed the greatest homology to those of Arabidopsis. Genomic Southern blot analysis, using RsCat1 cDNA as a probe, showed that catalases are encoded by small multigene family in the small radish. Nondenaturing polyacrylamide gels revealed the presence of several catalase isozymes, the levels of which varied among the organs examined. The isozyme activities were assigned the individual catalase genes by Northern analysis using total RNA from different organs. The three catalase genes were differentially expressed in response to treatments such as white light, xenobiotics, osmoticum, and UV. Their expression in seedlings was controlled by the circadian clock under a light/dark cycle and/or in constant light. Interestingly, RsCat1 transcripts peaked in the morning, while those of RsCat2 and RsCat3 peaked in the early evening. Our results suggest that the RsCat enzymes are involved in defense against the oxidative stress induced by environmental changes.

  • The cultivated radish (Raphanus sativus L.) is a major vegetable crop in the world wide and fast-growing species that grows inhabitats of six continents. It is very important to determine hybrid seed purity in the production of hybrid Brassica vegetable seeds to avoid unacceptable contamination with self-inbred (sib) seeds. The use of random amplified polymorphic DNA (RAPD) markers for evaluating seed purity in $F_2$-hybrid radish cultivars demonstrated. One hundred eighty seeds from the F1 male and female harvest were subsequently screened for seed purity using 13 primers. The 13 primers result in 17 cultivar-specific bands and 23 variable RAPD bands scored for cultivar. RAPD analysis of hybrid seeds from the harvest revealed 128 seeds tested except underdevelopment and decayed seeds were sibs. Especially, $F_2$ hybrids of radish, OPC13, OPD20 were presented clear hybrid bands. It maintains higher than average level of genetic diversity compared with their correspondent parents. RAPD amplification of DNA extracted from germinated individuals from the female harvest reveal that 10 of 208 seeds tested were self-inbred (4.8%). RAPD analysis of hybrid seeds from the male harvest revealed 7 of the 208 seeds tested were sibs (3.4%). The RAPD may lead to a better insight in to the hybrid seed purity.

  • A specific DNA fragment from Korean radish (Raphanus sativus L.) was amplified by performing PCR with oligonucleotide primers which correspond to the highly conserved regions of plant peroxidases. The size of the PCR product was ca. 400 bp, as expected from the known plant peroxidase genes. Comparison of the nucleotide and deduced amino acid sequences of the PCR product to those of other plant peroxidase-encoding genes revealed that the amplified fragment corresponded to the highly conserved region I and III of plant peroxidases. By screening a genomic library of Korean radish using the amplified fragment as a probe, two positive clones, named prxK1 and prxK2, were isolated. Restriction mapping studies indicated that the 5.2 kb Sail fragment of the prxK1 clone and the 4.0 kb EcoRI fragment of the prxK2 clone encode separate isoperoxidase genes. Analyses of the promoter region of the prxK1 clone shows that putative CAAT box, CMT box, and TGA1b binding sequence (5' TGACGT) are present 718 bp upstream from the start codon.
