A quick and reliable method for identifying meat origin is developed to ensure species origin of livestock products for consumers. The present study examined the identification of meat sources (duck, chicken, goat, deer, pig, cattle, sheep, and horse) using PCR by exploiting the mitochondrial 12S rRNA and mitochondrial cytochrome b genes. Species-specific primers were designed for some or all mitochondrial 12S rRNA nucleotide sequences to identify meat samples from duck, chicken, goat, and deer. Mitochondrial cytochrome b genes from pig, cattle, sheep, and horse were used to construct species-specific primers, which were used to amplify DNA from different meat samples. Primer sets developed in this study were found to be superior for detecting meat origin when compared to other available methods, for which the discrimination of meat origin was not equally applicable in some cases. Our new development of species-specific primer sets could be multiplexed in a single PCR reaction to significantly reduce the time and labor required for determining meat samples of unknown origin from the 8 species. Therefore, the technique developed in this study can be used efficiently to trace the meat origin in a commercial venture and help consumers to preserve their rights knowing origin of meat products for social, religious or health consciousness.

The liverwort Pellia borealis is a diploid, monoecious, allopolypliod species (n=18) that as it was postulated, originated after hybridization and duplication of chromosome sets of two cryptic species: Pellia epiphylta-species N (n=9) and Pellia epiphylla-species 5 (n=9). Our recent results have supported the allopolyploid origin of P.borealis. We have shown that the nuclear genome of P.borealis consists of two nuclear genomes: one derived from P.epiphylla-species N and the other from P.epiphylla-species 5. In this paper we show the origin of chloroplast and mitochondrial genomes in an allopolyploid species P.borealis. To our knowledge there is no information concerning the way of mitochondria and chloroplast inheritance in Brophyta. Using an allopolyploid species of p. borealis as a model species we have decided to look into chloroplast and mitochondrial genomes of P.borealis, P.epiphylla-species N and P.epiphylla-species S for nucleotide sequences that would allow us to differentiate between both cryptic species and to identify the origin of organelle genomes in the alloploid species. We have amplified and sequenced a chloroplast $tRNA^{Leu}$ gene (anticodon UAA) containing an intron that has shown to be highly variable in a nucleotide sequence and used for plant population genetics. Unfortunately these sequences were identical in all three liverwort species tested. The analysis of the nucleotide sequence of chloroplast, an intron containing $tRNA^{Gly}$ (anticodon UCC) genes, gave expected results: the intron nucleotide sequence was identical in the case of both P.borealis and P.epiphyllaspecies N, while the sequence obtained from P.epiphyllasperies S was different in several nucleotide positions. These results were confirmed by the nucleotide sequence of another chloroplast molecular marker the chloroplast, an intron-contaning $tRNA^{Lys}$ gene (anticodon UUU). We have also sequenced mitochondrial, an intron-containing $tRNA^{Ser}$ gene (anticodon GCU) in all three liverwort species. In this case we found that, as in the case of the chloroplast genome, P.borealis mitochondrial genome was inherited from P.epiphylla-species N. On the basis of our results we claim that both organelle genomes of P.borealis derived from P.epiphylla-species N.

This paper provides a basis for investigating 'The Origin of Artificial Species,' as a robot can be considered as an artificial creature. To design an artificial creature, its general internal architecture is presented and its artificial chromosomes are proposed as its essential components. Rity as an artificial creature is developed in a virtual world of PC to test the world's first robotic 'chromosomes,' which are a set of computerized DNA (Deoxyribonucleic acid) codes for creating robots (artificial creatures) that can have their own personality, and can ultimately reproduce their kind, or even evolve as a distinct species. The effectiveness of the artificial chromosomes is demonstrated by implanting the genetic code into two Ritys living in a virtual world, in order to define their personality.

Chinese crude drug 'Se Sin'(細辛)has been used to cure headache, cough and expectorant. To the botanical origin of 'Se Sin', Zhong-yao-zhi(中葯志) reported Asarum heterotropoides var. mandshuricum. A. sieboldii and A. sieboldii var. seoulensis, and Zhong-yao-da-ci-dian(中葯大辭典) reported Asarum heterotropoides var. mandshuricum and A. sieboldii of Aristolochiaceae. In Korea, this crude drug has been used as a Korean folk remedy for tothache and aromatic. The botanical origin of 'Se Sin' is considered to be Asarum species of Aristolochoaceae. But there has no pharmacognostical confirmation on it. To clarify the botanical origin of 'Se Sin', we studied on the anatomical characteristics of Asarum species growing wildly in Korea i.e. A. maculatum, A. sieboldii, A. sieboldii var. seoulensis, and of 'Se Sin' from Korea on Korean market. Through our studies, the botanical origin of 'Se Sin' from Korea was proved to be whole plant of Asarum sieboldii and A. sieboldii var. seoulensis.

To elucidate the ancestry of the allopolyploids E. stevenii and E. boöphthona, I examined eleven isozyme loci and 24 morphological characters from 28 populations representing five related Euphorbia species from Australia. According to an analysis of genetic and morphological data, three diploid species differentiated recently, but two independent polyploid species are estimated to have differentiated a relatively long time ago. Fixed heterozygosity for most isozymes in E. stevenii and E. boöphthona strongly suggests that these two species are allopolyploids rather than autopolyploids. The isozyme profiles of E. stevenii indicate that it is an allopolyploid that evolved from interspecific hybridization between the diploid E. tannensis and unidentified or extinct tetraploid species. In addition, isozyme patterns strongly suggest that E. stevenii was one of the ancestors of E. boöphthona. However, E. boöphthona showed a large number of fixed alleles that were not detected in any other Australian Eremophyton species. The most likely hypothesis for the origin of E. boöphthona is that it was formed by hybridization and chromosomal doubling between an extinct diploid species and the hexaploid E. stevenii.

Objects : This study aimed to identify the origin species of Ulmi Cortex and Ulmi Semen Pasta. Methods : I searched for different types of 'Yu(楡)' from Zhong Xiu Zheng Huo Jing Shi Zheng Lei Bei Yong Ben Cao (重修政和經史證類備用本草) of the Song Dynasty, then compared the descriptions of Yu with real life species. Items that were inconsistent were sequentially deleted to finally find the original species that satisfies all conditions. Results : There were five types of Yu : Jiyu(地楡), Jayu(刺楡), Langyu(郞楡), Goyu(姑楡), and Baekyu(白楡). Jiyu was Sanguisorba officinalis or Sanguisorba officinalis var. longifolia which was a herb. Jayu was Hemiptelea davidii (Hance) Planch. which had thorns on its branches. Ulmus laciniata had leaves that split into three branches. Langyu was Ulmus parvifolia which beared fruit in the fall. For these reasons, the four items above were ruled out. The fruit of Goyu was Ulmi Semen Pasta, which was the largest among fruits and was therefore Ulmus macrocarpa. The fruit of Baekyu was Yuhyup(楡莢) and the ancient coin Yuhyupjeon(楡莢錢) was resembled Yuhyup. The normal pulse of the lung resembled the appearance of falling Yuhyup. The peel of Baekyu was Yubaekpi(楡白皮), and when it was removed from coarse bark, contained an abundance of white sap; the place where this sap overflowed on the stem bark was white, therefore Baekyu was identified as Ulmus pumila. Conclusions : From the results above, the origin species of Ulmi cortex was Ulmus pumila and the origin species of Ulmi Semen Pasta was Ulmus macrocarpa.

The Chinese crude drug, 'Yong Dam (龍膽)' which is derived from the root of Gentiana plants of the family Gentianaceae, has been used as remedy for stomachic, intestinal catarrh, convulsion, etc. With regard to the botanical origin of 'Yong Dam', it has been considered to be Gentiana species of Gentianaceae, especially Gentiana scabra, but there has no pharmacognostical confirmation on it. To clarify the botanical origin of 'Yong Dam' from Korea, we studied on the anatomical characteristics of Gentiana species growing wild in Korea i.e. Gentiana scabra var. buergeri, G. uchiyamai, G. triflora, G. axillariflora var. coreana and of 'Yong Dam' from Korea on Korean market. Through our studies, the botanical origin of 'Yong Dam' from Korea was proved to be Gentiana scabra var. buergeri and Gentiana axillariflora var. coreana.
