  • Temperature affects the firing pattern and electrical activity of neurons in animals, eliciting diverse responses depending on neuronal cell type. However, the mechanisms underlying such diverse responses are not well understood. In the present study, we performed in vitro recording of abdominal ganglia cells of Aplysia juliana, and analyzed their burst firing patterns. We identified atypical bursting patterns dependent on temperature that were totally different from classical bursting patterns observed in R15 neurons of A. juliana. We classified these abnormal bursting patterns into type 1 and type 2; type 1 abnormal single bursts are composed of two kinds of spikes with a long interspike interval (ISI) followed by short ISI regular firing, while type 2 abnormal single bursts are composed of complex multiplets. To investigate the mechanism underlying the temperature dependence of abnormal bursting, we employed simulations using a modified Plant model and determined that the temperature dependence of type 2 abnormal bursting is related to temperature-dependent scaling factors and activation or inactivation of potassium or sodium channels.

  • 도열병균(Pyricularia oryzae) 균사체의 esterase 동위효소 pattern이 배양조건에 의하여 변화되는가를 $10\~25\%$ polyacrylamide gradient slab gel을 사용하여 알아보았다. 배양기간에 따라 배양 24일까지 동위효소 pattern은 변하지 않았지만 특징 band의 효소량에는 차이가 있었다. 탄소원(glucose, fructose, maltose, sucrose, starch), 단포자분리균주간, 계대배양 및 세포벽재생균주간의 동위효소 pattern은 변함이 없었다.

  • 영지(靈芝)버섯(Ganoderma lucidum (Fr.) Karst.)의 16개 균주간(菌株關) 특성을 전기영동법(電氣泳動法)을 사용(使用)하여 단백질(蛋白質) pattern과 esterase, LAP의 동립효소(同位酵素) pattern에 의해 비교(比較) 관찰하여 다음과 같은 결과를 얻었다. 1. 자실체(子實體)의 esterase의 band pattern은 각(各) 균주간(菌株間) 특정 band의 유 무(有 無)와 위치(位置) 등에 의해 분류(分類) 할 수 있었으며 자실체(子實體)의 형태(形態)가 유사한 것은 band pattern에서도 유사하였다. 2. 동일균주(同一菌株)에서 편각(扁角)과 녹각형태(鹿角形態)로 형성(形成)된 자실체(子實體)의 esterase band pattern은 서로 동일(同一)한 pattern을 보였다. 3. 균주간(菌株間) 유연관계인 유사도 지수는 12.5%에서 100%의 변이 폭을 보였다. 특히 6과 7번의 두 균주간(菌株間)과 13,14,15,16번의 4균주간(菌株間)은 유사도지수가 100%이므로 유전적(遺傳的)으로 동일(同一)한 균(菌)이라 사료(思料)된다. 4. 균사(菌絲)의 단백질(蛋白質)과 esterase의 band pattern은 자실체(子實體)의 pattern과는 달랐으며 자실체(子實體)에서 동일(同一)한 pattern을 보였던 균주간(菌株間)에서도 균주간(菌株間) 특성을 가장 잘 보여 주었으므로 영지(靈芝)버섯 분류(分類)에는 균사(菌絲)의 esterase pattern이 가장 적합하다.

  • This study is to examine the characteristics of fabrics in Koryo dynasty by reviewing the fabrics for enshrining oblations inside a buddhist statue in MoonSoo temple, which are currently possessed in SooDuk temple. The research results follows : The fabrics are 33 pieces in total : 28 Pieces of normal fabrics, 5 pieces of fabrics that is used for covering the five grains, and others like variegated silk threads. Out of 33 pieces of fabrics are there 31 pieces of silk and 2 pieces of ramie. The tabby fabrics, which have the most pieces among the fabrics, are 11 pieces in total. There are 1 piece of designed tabby fabri. whose patterns are expressed by dyeing. as well as non-designed tabby fabric. The twill fabrics are 8 pieces in total. Its patterns are mainly the type that small patterns are consecutively reiterated. And they have various patterns including plant patterns, such as lotus pattern, flower pattern. etc., animal patterns such as dragon pattern. etc., geometric patterns. such as turtoise-shell pattern. swastika, etc. The leno and gauze fabrics are 1 piece of 4-end complex designed-gauze and 1 piece of gill gauze. The compound woven fabrics are 2 pieces of brocaded gauze and 3 pieces of brocaded twill. Brocaded gauze is a kind of brocaded fabrics and is made by adding a gold thread between wefts of already weaved gauze. The figured fabrics are 1 piece of tabby fabric, 6 pieces of twill fabrics, 4 pieces of leno and gauze fabrics, and 5 pieces of compound woven fabrics. All of them are 16 pieces out of all 33 pieces and amount to almost 50%. Single-patterned fabrics, that is one pattern is expressed individually, are much more than any others. Plant patterns are the ones that are used the most.

  • In this study, plant regeneration through in vitro culture from plantlet stems of Yooja (C. junos Sieb.) and trifoliate orange (P. trifoliata Rafin.) was attempted to make mass-production system of virus-free plants having the same genotype with mother plant. In order to investigate physiological change depending on the developmental stage of plant regeneration, the changes of total protein, peroxidase and esterase activity and their isozyme patterns as well were examined in 1/2 MS medium. The results are as follows : 1. The MS medium for the optimal callus induction and shoot formation was utilized. The medium was supplemented either with 2,4-D and Kinetin or with BA and NAA. The optimal concentrations were the combination of 1.0mg/ 2,4-D +0.3mg/ Kinetin and 1.0mg BA +0.3mg NAA in callus induction and shoot formation, respectively. 2. For the plant regeneration from somatic embryos, 1/2 MS medium was used with supplements of growth regulators (free, 1.0mg/ IBA +1.0mg/ BA ,0.5mg/ IBA +0.5mg/ BA). Shooting and rooting were the best in the treatment of 0.5mg/ IBA and 0.5mg/ BA combination. 3. The total protein content has a tendency of increase with the developmental stage of embryo, but it was decreased at the plantlet. Also it was the highest at 8 and 6 weeks stage in C. junos Sieb. and P. trioliata Rafin, respectively. In the SDS-PAGE pattern of protein, C. junos Sieb. showed bands of 29.0 and 40kDa at 10 weeks. The 45,66 and 97.4 kDa bands at 10 weeks of culture were shown in P. trifoliata Rafin. 4. The highest esterase activity was shown at the 6 and 8 weeks of culture in C.junos Sieb. and P. trifoliata Rafin.., respectively. 5. Esterase isozyme patterns were shown difference according to the developmental stage. In C. junos Sieb. a new band was observed at pl 7.7 following 4 weeks culture. On the other hand, new bands in P. trifoliata Rafin. were observed at pl 7.5~6.5 following 4 and 6 weeks culture, respectively.

  • Nicotiana ($NR^{-}/SR^{+}$)과 N. glutinosa간 전기적 (0.5 MHz의 AC와 2 ms 동안 1 kV DC) 원형질체 융합에서 선발은 1.2mg/ml의 streptomycin이 첨가된 $MSNO_3$ 배지를 통하여 가능하였으며, 이 융합세포의 분열이 지속되어 형성된 녹색 세포괴를 얻었다. 이 녹색 세포괴에서 재분화된 4개의 식물 계통들은 꽃과 잎에서 모식물체의 특징을 보였으며, 엽조직의 peroxidase 동위효소 유형 분석에서도 양쪽 모식물체의 특성을 갖고 있었다. XhoI의 제한효소 절단에 의해 융합식물체 계통의 엽록체 DNA의 분석에서도 융합체 식물계통들은 N. tabacum과 N. glutinosa에서 공통되는 단편과 모식물체 유래 단편을 보였고, 이 융합식물계통들 중 한 계통은 9개의 공통 단편에 N. tabacum의 1개 단편, N. glutinosa의 2개 단편이 추가되어 있는 유형을 보여 N. tabacum과 N. glutinosa의 엽록체 게놈을 모두 소유하고 있다는 것을 보여주었다.

  • Single-molecule real-time (SMRT) sequencing allows identification of methylated DNA bases and methylation patterns/motifs at the genome level. Using SMRT sequencing, diverse bacterial methylomes including those of Helicobacter pylori, Lactobacillus spp., and Escherichia coli have been determined, and previously unreported DNA methylation motifs have been identified. However, the methylomes of Xanthomonas species, which belong to the most important plant pathogenic bacterial genus, have not been documented. Here, we report the methylomes of Xanthomonas axonopodis pv. glycines (Xag) strain 8ra and X. campestris pv. vesicatoria (Xcv) strain 85-10. We identified $N^6$-methyladenine (6mA) and $N^4$-methylcytosine (4mC) modification in both genomes. In addition, we assigned putative DNA methylation motifs including previously unreported methylation motifs via REBASE and MotifMaker, and compared methylation patterns in both species. Although Xag and Xcv belong to the same genus, their methylation patterns were dramatically different. The number of 4mC DNA bases in Xag (66,682) was significantly higher (29 fold) than in Xcv (2,321). In contrast, the number of 6mA DNA bases (4,147) in Xag was comparable to the number in Xcv (5,491). Strikingly, there were no common or shared motifs in the 10 most frequently methylated motifs of both strains, indicating they possess unique species- or strain-specific methylation motifs. Among the 20 most frequent motifs from both strains, for 9 motifs at least 1% of the methylated bases were located in putative promoter regions. Methylome analysis by SMRT sequencing technology is the first step toward understanding the biology and functions of DNA methylation in this genus.

  • Leaf mesophyll protoplasts of Nicotiana tabacum (nitrate reductase deficient mutant) were fused with cell suspension protoplasts of albino Petunia inflata in an electric field. Hybrid cell colonies were selected for nitrate reductase proficiency and chlorophyll synthesis. Five hybrid plant lines, regenerated from the selected calli lines, were analysed by electrophoresis, number of chromosomes and morphological characters. Somtic hybrid plants showed both parent patterns in the isozymesof isoleucine aminopeptidase and esterase. The hybrids had the expected chromosome number of 62 and exhibited an intermediate floral morphology when compared with the parents, but plant height and leaf arrangement were similar to N. tabacum.
