To study the effects of metal ions on the activity of anti-oxidase enzymes, the activity of superoxide dismutase (SOD) and peroxidase (POD) and isozyme patterns of Brassica juncea have been studied after treating with CD, Cu, Zn, and Al. The activity of SOD after treating with metal ions was higher than that of untreated control. SOD activity in leaves increased by treatment of 50 ppm of Zn and 500 ppm of Al. POD in stems gave highest activity after treating with 500 ppm of Cu. When the activity was compared by plant parts, lowest POD activity was observed in leaves in which protein content was higher than other tissues. When the activity was expressed as percentage of control, SOD activity was increased after treating with metal ions. SOD activity in leaves and roots of metal treated plant was significantly increased under the metal ions stress conditions. In the roots of 50 ppm of Zn treated plant, SOD activity was extremly high. POD activity was inhibited with Cd and Zn treatment in all parts of the plant. However, in leaves and stems, there was marked increase in activity after treating with Cu. The patterns of SOD isozyme after metal treatment show that two bands were stained in all metal ion treated and that no new band appeared. POD isozyme band intensity resulting from the treatment of metal ions was in order of roots > stems > leaves, but there was no significant difference.

The genetic variability and population structure of apple mosaic virus (ApMV) have been studied; however, synonymous codon usage patterns influencing the survival rates and fitness of ApMV have not been reported. Based on phylogenetic analyses of 52 ApMV coat protein (CP) sequences obtained from apple, pear, and hazelnut, ApMV isolates were clustered into two groups. High molecular diversity in GII may indicate their recent expansion. A constant and conserved genomic composition of the CP sequences was inferred from the low codon usage bias. Nucleotide composition and relative synonymous codon usage (RSCU) analysis indicated that the ApMV CP gene is AU-rich, but G- and U-ending codons are favored while coding amino acids. This unequal use of nucleotides together with parity rule 2 and the effective number of codon (ENC) plots indicate that mutation pressure together with natural selection drives codon usage patterns in the CP gene. However, in this combination, selection pressure plays a more crucial role. Based on principal component analysis plots, ApMV seems to have originated from apple trees in Europe. However, according to the relative codon deoptimization index and codon adaptation index (CAI) analyses, ApMV exhibited the greatest fitness to hazelnut. As inferred from the results of the similarity index analysis, hazelnut has a major role in shaping ApMV RSCU patterns, which is consistent with the CAI analysis results. This study contributes to the understanding of plant virus evolution, reveals novel information about ApMV evolutionary fitness, and helps find better ApMV management strategies.

Hypersensitive cell death of plants during incompatible plant-pathogen interactions is one of the efficient defense mechanisms of plants against pathogen infections. For better understanding of the molecular mechanisms involved in the plant hypersensitive response (HR), TMV-induced biotic plant cell death and CuSO4-induced abiotic plant cell death were compared in terms of expression patterns of ten different defense-related genes as molecular markers. The genes include five pathogenesis-related protein genes, two plant secondary metabolite-associated genes, two oxidative stress-related genes and one wound-inducible gene isolated from tobacco. Northern blot analyses revealed that a same set of defense-related genes was induced during both biotic and abiotic cell death but with different time and magnitude. The expression of defense-related genes in tobacco plants was temporarily coincided with the time of cell death. However, when suspension cell cultures was used to monitor the expression of defense-related genes, different patterns of the gene expression were detected. This result implies that three are common and, in addition, also different branches of signaling pathways leading to the induced expression of defense-related genes in tobacco during the pathogen- and heavy metal-induced cell death.

The purpose of this study is to analyze the characteristics of the Chinese Miao people's Batik patterns and provide data in the field of fashion design for the utilization of the traditional patterns. This study investigated and analyzed the regional characteristics of Batik dyeing, which was listed on China's national intangible cultural heritage list; Danzhai, Anshun, Huangping, and Gonghyeon. The expressive characteristics were classified into four categories: symbolism, abstraction, decorativeness, and playfulness. The results are as follows. First, symbolism can be classified into the origins of the Miao, symbols of faith, history of migration, and the symbols of status with Batik patterns from different regions, seemingly involving various symbolic implications. Due to the absence of letters, Miao people expressed their emotions and history in the design patterns. A series of developments in recent years has led to incorporating the temperament of the Miao people, history of migration, expression of emotions, and ideal hopes in Batik dyed design patterns and the symbolic functions have been significantly emphasized. Second, the decorativeness is mainly characterized by repeated patterns of the Miao Batik dyeing design. The overall patterns demonstrate design features characterized by regularization and simplification, along with a sense of rhythm with the unique arrangement of patterns. Third, the abstractness of the Batik dyeing design patterns is often found in plant and animal patterns, properly delivering new designs created by Miao women by extracting and rearranging various elements, including dots, lines, and faces shown in natural images. Fourth, playfulness is expressed by the transformation and distortion of Miao Batik patterns, and were created by applying patterns or other elements to original forms to express animal or plant patterns in a playful way.

The purpose of this study was to evaluate the preference of image for modern application of Korean traditional patterns. A survey was conducted using the randomly selected 292 undergraduate women students of Taegu city. The degree of interest and preference in Korean traditional style or something like that had measured by 5 scale method. And then they had two groups which are interest/non-interest group, and preference/non-preference group in Korean traditional style. Also, preference of Korean traditional patterns was measured by 5 scale method. The image of Korean traditional patterns consisted of semantic differential scales. Analysis was by frequency, percentage, and mean. For difference of groups analysis was by t-test. The results were as follows:1. For the survey, 53.8% showed the interest and 40.4% did the preference for the traditional patterns. There was the positive correlation(0.782) between the degree of the interest and preference. 2. Among twenty traditional patterns, the patterns of plants and nature were very preferred, but the patterns of geometrical things was not preferred. 3. For the nature pattern, the image seemed to be elegant and feminine(womanly). For the plant pattern, the image seemed to be feminine, neat, weak, light and mild. For the animal pattern, the image seemed to be heavy, gorgeous, deluxe, virile(manly), strong and active. Last, for the geometrical pattern, the image seemed to be elegant, deluxe, rigid and strong. 4. Between the interest／non­interest groups, there was the significant difference in pattern of cloud, mountain, lotus flower, plum blossoms, orchid, dragon, chinese phoenix and bogy. Especially, for the orchid pattern, the preference difference between these groups was large. 5. For the plant pattern, the image difference between these groups was very large as the elegant-rustic image. Especially, the interest group evaluated as the elegant image. 6. Between the preference／non­preference groups, there was the strongly significant difference in the preference for the orchid pattern. 7. For the geometrical pattern, the image difference between these groups was very large as the mild­cold image. Especially, the preference groups evaluated as the cold image.
