  • The dyeability of the cotton fabric with Brassica campestris extract was investigated. The colorant was extracted with methanol. Cotton fabrics were dyed at various conditions such as temperatures, concentrations, dyed times, and mordanting methods. The maximum wavelength of extract was 421nm. The highest K/S value was showed at 200% dye concentration at $60^{\circ}C$, 45 minutes. As the effect of dyed temperature and mordanting on dyeability was not great, the Brassica campestris was one-color dyestuff.

  • This study was investigated to establish the optimum conditions of dyeing silk fabric with Brassica campestris. This experiment was done under different dyeing conditions of dye concentration, dyeing temperature, dyeing time, dyeing repeating times, and mordants which were treated pre, syn, and post methods. The effects of dyeing conditions and mordanting were evaluated in terms of dyeaffinity(K/S value) and CIE-Lab color factors. Also, the effect of mordanting on color fastnesses was assessed. The dyeaffinity increased remarkably as dye concentration increased up to 200% owf. The dyeaffinity increased continuously with dyed temperature and reached dyeing equilibrium at $80^{\circ}C$. The maximum dyeaffinity was observed at 30minutes of dyeing time. In the relationship between the K/S value and dyeing repeating times, the K/S value became higher as repeating time was increased. The changes of surface color and colorfatness of dyes were not increased greatly on all mordanting states. The extracts of Brassica campestris produced mainly yellow color in silk fabric. The antimicrobial activity existed slightly as the ratio of 22.7%.

  • Tah tasai chinese cabbage (Brassica campestris var. narinosa), a vegetable plant popularly consumed as several-days-old seedlings in oriental countries, can be easily cultivated using a simple appliance. We demonstrated that Agrobacterium-mediated transformation via vacuum infiltration (agroinfiltration) resulted in a successful transient GUS gene expression in tah tasai chinese cabbage seedlings. Pre-germinated seeds were found to be more susceptible to Agrobacterium infection than one-day-old or two-days-old seedlings. We also demonstrated that hydrogen peroxide (HPO) treatment increased GUS expression especially for two-days-old seedlings. In ELISA using seedlings transformed with hepatitis B surface antigen (HBsAg) DNA by agroinfiltration, HBsAg protein synthesis increased more than two folds by HPO treatment to two-days-old seedlings in comparison to the mock-treated pre-germinated seeds.

  • This study was performed to evaluate the remediation efficiency by Helianthus annuus, Brassica juncea and Brassica campestris on the soil contaminated with nickel, zinc and lead, respectively. The growth rates fell down under 60% in the condition of over 700 mg/kg of zinc for Brassica campestris, 300 mg/kg of lead for Helianthus annuus, and 150 mg/kg of nickel for Brassica juncea on the basis of heavy metal concentration in the soil, because of its toxicity. Also, the hyperaccumulators showed the maximum heavy metal contents in their biomass after 90 days of cultivation. The accumulated heavy metal content per kilogram of hyperaccumulator was 0.65 mg of nickel in Brassica juncea, 0.14 mg of zinc in Brassica campestris, and 0.06 mg of lead in Helianthus annuus, respectively. Additionally, 73.2% of nickel accumulated in Brassica juncea and 95.1% of zinc accumulated in Brassica campestris were concentrated in the upper site of crop like stem and leaves. However, in the case of Helianthus annuus, 83.7% of lead was accumulated in the root.

  • Protoplasts isolated from inbred lines of Brassica oleracea L. var capitata (cabbage) and Brassica campestris L. ssp. pekinensis (Chinese cabbage) were fused by PEG-mediated method, and somatic hybrid cells were differentiated into plants. for the identification of somatic hybrid plants, ploidy level, plant morphology, and cytological analysis were performed. All of the regenerated plants derived from fused protoplasts were shown to be 2X-4X, or higher ploidy level, presumably due to somatic hybridization or chromosome doubling. The morphology of leaves, petioles, and flowers showed an intermediate phenotype between Chinese cabbage and cabbage. Chromosome numbers in these somatic hybrids ranged mostly from 33 to 38. According to Genomic in situ hybridization (GISH) pattern, signals from both fusion parents of B.campestris or B.oleracea were detected in different colors when chromosomes of putative somatic hybrids were observed.

  • Members of the genus Brassica, which are known as oil crops or cruciferous vegetables, are widely cultivated in Canada, Australia, Asian and Europe. Because Brassica species have high yields, are well adapted to their environments, and are self-incompatible, the germplasm is abundant. Previous studies have reported abundant genetic diversity even within Brassica subspecies. In Korea, fresh cabbage leaves are eaten with roast meat, and to meet the current popular demand, new varieties are being increasingly bred. To determine the genetic diversity and relationships among the cabbage vegetables in Korea, we evaluated the genetic variation of 18 accessions based on 5S and 18S ribosomal RNA (rRNA) gene sequences. We detected many variable nucleotide sites, especially in the 5S rRNA gene sequences. Because the length of the 18S rRNA gene might influence the dissimilarity rate statistics, we used both the 5S and 18S sequences to analyze the phylogenetic relationships. S7 (B. oleracea) showed the most distant phylogenetic relationship with the other Brassica species. Interestingly, B2 (B. oleracea), B15, and B18 (B. campestris) have three different types of leaf profiles, and were divided into one group, and the other Brassica species formed another group. Statistical analysis of interspecies and intraspecies genetic distances revealed that B. campestris L. showed higher genetic diversity than B. oleracea L. This work provides additional data that facilitates the evaluation of the genetic variation and relationships among Brassica species. The results could be used in functional plant breeding programs to improve Brassica crops.

  • Objectives : Brassica campestris var narinosa (BCN), Canavalia gladiata DC semen (CGD) and their combinational prescription (BCN+CGD) have been use to demonstrate to regulate hematopoiesis. In the current study, we investigated whether Brassica campestris var narinosa, Canavalia gladiata DC semen and their combinational prescription is related to hemato-potentiating function using Sca-$1^+$ hematopoietic stem cells (Sca-$1^+HSCs$) as a testing system. Methods : Sca-$1^+HSCs$ isolated from femur in C57bl/6 mice with leukopenia and thrombocytopenia induced by cyclophosphamide (CTX). Then, Real-time PCR was performed to measure the mRNA expression, ELISA and haematopoiesis-related gene (EPO, TPO, IL-3, SCF, c-kit, GM-CSF), the phosphorylation of JAK2, GATA-1 and STAT-5a/b were observed by western blot, and the numbers of $CD117^+/Sca-1^+$ cell and the number of granulocyte erythrocyte monocyte macrophage colony-forming units (CFU-GEMM) and erythroid burst forming units (BFU-E), semisolid clonogenic assay was performed. Result : When Sca-$1^+HSCs$ were treated with Brassica campestris var narinosa, Canavalia gladiata DC semen and their combinational prescription with rIL-3/rSCF, the expression of haematopoiesis-related (EPO, TPO, IL-3, SCF, c-kit, and GM-CSF) were significantly increased at the levels of mRNA as well as production in Sca-$1^+HSCs$. Additionally, CGS enhanced phosphorylation of JAK2, GATA-1, and signal transducer and activator of transcription-5a/b (STAT-5a/b) in Sca-$1^+HSCs$. Furthermore, their combinational prescription (BCN+CGD) significantly enhanced the growth rate of granulocyte erythrocyte monocyte macrophage colony-forming units (CFU-GEMM) and erythroid burst forming units (BFU-E) in vitro. Conclusion : These result suggest that Brassica campestris var narinosa (BCN) and Canavalia gladiata DC have hematopoietic enhancement via hematopoietic cytokine-mediated JAK2/GATA-1/STAT-5a/b pathway, and their combinational prescription (BCN+CGD) has superior hematopoietic enhancement to those of individual extracts.
