The present researches were carried out to investigate the effects of gibberellic acid on the appearance of isozyme patterns of esterase, phosphatase, amylase and peroxidase, also to investigate if there were any differences of the isozyme patterns among root, shoot and seeds of rice plants. It was noticed that the isozyme patterns of the above tested enzymes were differ among the organs, root, shoot and seed. The GA treated plants showed difference of esterase patterns in root from Akibare and the difference in shoot and root from Yushin, phosphatase patterns in root from Akibare. However, the GA did not affect isozyme patterns of amylase or peroxidase. The seed should be the suitable organ to study isozyme patterns for genetics or variety characterization of rice plant.

The microtuber was efficiently formed on SH medium containing 9% sucrose from the in vitro propagated shoot of potato (Solanum tuberosum cv. Sumi). In order to investigate gene expression depending on the development stage of microtuber, we examined the changes of peroxidase and esterase activities, and their isozyme patterns as well. Peroxidase and esterase activities were the highest at the 7 day-culture of the microtuber and subsequently decreased on the stage of microtuberization, whereas esterase activity increased at the stage of 60 day-culture. However, their activities in the ordinary tuber were higher than those of 60 day-cultured microtuber. In addition, in the peroxidase isozyme pattern two new bands of pI 7.05 and pI 4.65 were appeared at the 15- day and 60 day-cultures, respectively, as shown by isoelectric focusing. Various bands in the sterase isozyme pattern were shown at the 7 day-culture, and the band patterns were a large difference, comparing those of shoot and tuber. New bands in the esterase isozyme pattern also appeared at the 15 day- (pI4.52) and 60 day-cultures (pI 4.48). These results suggest that the changes of peroxidase and esterase activities and isozyme patterns are an important factor in the differentiation and development of potato.

Ten soybean varieties were cultivated to know the varietal differences of lodging patterns of soybean plants under three different plant populations in two growing seasons in 1981. Lodging plant percentage was increased in higher plant populations and lodging responses to plant populations were different between soybean varieties. Lodging plant percentage was also increased by the growth of soybean plant and the patterns of lodging development along with the growth stages could be classified into four types by the varieties used, relatively lwoer iodging plant percentage from early to later growth stage but high in late and relatively high in middle stage but low in later stage. Williams, indeterminate type, and Kang-lim, determinate type, showed resistance to lodging under six different cultural practices, but Jang-yeop-kong, Dan-yeop-kong and Hwang-keum-kong showed resistance to lodging under specific cultural conditions among ten varieties used. Most of the plants lodged showed main stem bending in parts above first stem node in higher plant population and lodging resistant varieties showed lower frequency of stem bending lodging compared with those of lodging susceptible varieties.

Many of plant defense responses are consequence of transcriptional activation of related genes. We have developed a modified differential screening procedure to isolate tobacco genes that are involved in the defense responses against TMV infection. A cDNA library was constructed from Nicotiana glutinosa leaves infected by TMV under temperature shift conditions. Each of plasmid DNA in the library was hybridized on a set of slot blots to a pool of cDNA probes prepared from either TMV-infected or mock-treated tobacco leaves. Among 900 plasmid DNAs, 81 clones exhibiting significantly enhanced or reduced level of hybridization to either probe were selected for nucleotide sequencing. The clones were listed into 61 genes considering redundancy between the sequences. The genes were identified to be defense-related genes including PR-genes and genes involved in primary or secondary metabolisms. This results supports the implication that plant defense process entails a major shift in total cellular metabolisms rather than activation of a limited number of defense-related genes. Expression patterns of a number of defense-related genes. Expression patterns of a number of selected genes were examined in northern blot analyses. It is notable that the clone 630 of unknown function exhibits expression pattern similar to those of previously known PR-genes. Experiments to elucidate the roles in defense mechanism of a couple of genes newly identified in this study are in progress.

Using the knowledge base which contains the patterns and data of the past experience of a plant, a learning control method is suggested. The knowledge for controlling a plant is stored to the knowledge base and continually modified after performance evaluation of an applied control input. The performance of the resultant knowledge based control system is examined by an application to process.

Giemsa C-banding analysis with Korean rye strain revealed that individual chromosomes had characteristic banding patterns making it possible to distinguish the seven rye chromosomes one from another. It seems to be evident that B-chromosomes in rye contain proportionally more heterochromatin than autosomes.

This study examined the kinds, expression, techniques and arrangement of patterns for the traditional women's costume from 1995 to 2002 in North Korea. And the results were compared with South Korean. Conclusions are as follows : In the kinds of patterns the natural plant patterns were much more frequently used in North Korea. These tendency was same to South Korea. And the geometric patterns were more frequently used in South Korea. According to frequency in the expression of patterns, it was the realistic, geometric, stylized shape in North Korea. To the contrary it was the stylized, geometric, realistic shape in South Korea. In terms of decorative techniques, not only the traditional embroidery, gold leaf, multicolored stripes, but also modern collages, painting, beads, applique, flounce, ruffle were used in North Korea. Modern techniques were found comparatively a lot in North Korea, traditional techniques were found comparatively a lot in South Korea. In terms of arrangement of patterns, the modern arrangement was much more frequently used. And localized type of modern arrangement was found comparatively a lot in South and North Korea. Therefore traditional beauty was generally expressed by natural patterns, realistic shape and modern beauty was generally expressed by modern techniques and arrangement of patterns in North Korea.

Soybean (Glycine max (L.) Merr.) is a representative food resource. To preserve the integrity of soybean, it is necessary to protect soybean yield and seed quality from threats of various pests and diseases. Riptortus pedestris is a well-known insect pest that causes the greatest loss of soybean yield in South Korea. This pest not only directly reduces yields but also causes disorders and diseases in plant growth. Unfortunately, no resistant soybean resources have been reported. Therefore, it is necessary to identify the distribution and movement of Riptortus pedestris at an early stage to reduce the damage caused by insect pests. Conventionally, the human eye has performed the diagnosis of agronomic traits related to pest outbreaks. However, due to human vision's subjectivity and impermanence, it is time-consuming, requires the assistance of specialists, and is labor-intensive. Therefore, the responses and behavior patterns of Riptortus pedestris to the scent of mixture R were visualized with a 3D model through the perspective of artificial intelligence. The movement patterns of Riptortus pedestris was analyzed by using time-series image data. In addition, classification was performed through visual analysis based on a deep learning model. In the object tracking, implemented using the YOLO series model, the path of the movement of pests shows a negative reaction to a mixture Rina video scene. As a result of 3D modeling using the x, y, and z-axis of the tracked objects, 80% of the subjects showed behavioral patterns consistent with the treatment of mixture R. In addition, these studies are being conducted in the soybean field and it will be possible to preserve the yield of soybeans through the application of a pest control platform to the early stage of soybeans.

Toll-like receptors (TLRs) can recognize conserved molecular patterns and initiate a wide range of innate and adaptive immune responses against invading infectious agents. The aim of this study was to assess the transcript profile of mink TLRs (mTLRs) in mink peripheral blood mononuclear cells (PBMCs) and a range of tissues, and to explore the potential role of mTLRs in the antiviral immune response process. The results indicated that the mTLR partial nucleotide sequences had a high degree of nucleotide identity with ferret sequences (95-98%). Phylogenetic analysis showed that mammalian TLRs grouped into five TLR families, with a closer relationship of the mTLRs with those of ferret than the other mammalian sequences. Moreover, all the mTLRs were ubiquitously expressed in lymphoid organs (spleen and lymph nodes) and PBMCs. Interestingly, the mTLR expression patterns in lung, uterus, and heart showed quite a lot of similarity. Another remarkable observation was the wide expression of mTLR1-3 mRNAs in all tissues. Among the analyzed tissues, skeletal muscle was revealed to being the lowest repertoire of mTLR expression. Additionally, mink PBMCs exposed to the canine distemper virus revealed significant upregulation of mTLR2, mTLR4, mTLR7, and mTLR8 mRNAs, indicating that mTLRs have a role in innate immunity in the mink. Collectively, our results are the first to establish the basic expression patterns of mTLRs and the relationship between mTLRs and a virus, which will contribute to better understanding of the evolution and the functions of mTLRs in the innate immune system in minks.
