  • The spionid polychaete Scolelepis geniculata, originally described in Japan, is newly recorded in the Korean fauna. Specimens collected from the eastern and southern coasts of Korea between May 1999 and October 2002, stored in the invertebrate collection of the National Institute of Biological Resources, were examined based on their morphology. Scolelepis geniculata is morphologically most similar to S. yamaguchii from Japan and Korea but is distinguished by having branchiae separated from the notopodial lamellae in posterior chaetigers and notopodial prechaetal lamellae digitiform in anterior chaetigers instead of subtriangular. A detailed morphological description of S. geniculate, and an amended identification key to all Korean Scolelepis species is provided.

  • Vulpia octoflora (Walter) Rydb., a newly identified invasive alien species, was found in Gangcheon-ri, Yeoju-si, Gyeonggi-do, South Korea. It is native to North America and has been reported to be an invasive alien plant in Japan, Australia, and Ukraine. Vulpia octoflora is a weed that grows mainly in dry sandy or rocky soil and is frequently found along the roadside in open areas or in artificially disturbed sites. This species is similar to the recently confirmed alert alien species, V. bromoides (L.) Gray, but is readily distinguishable due to more florets per spikelet and a short awn of the lemma. A detailed species description, the geographical distribution, illustrations, photographs, and an identification key for all species of Vulpia that occur in Korea are provided.

  • The fish species Uraspis helvola and U. uraspis (family Carangidae, Perciformes) were collected from Korea, and described and compared based on morphological and molecular characters. Uraspis helvola and U. uraspis were clearly distinguished by differences in the beginning point of the straight lateral lines scales (dorsal fin soft rays 12th~13th in U. helvola vs. 15th~16th in U. uraspis), and in the naked area on the breast extends to the pectoral fin base (naked area half way in U. helvola vs. naked area widely connected in U. uraspis). Molecular analysis using 530 base-pairs of mitochondrial DNA cytochrome c oxidase subunit I gene strongly supported the morphological identification. We described it as the new Korean record, and proposed the new Korean name "min-jeon-gaeng-i-sok" for the genus Uraspis, and "heuk-gi-min-jeon-gaeng-i" for the species U. uraspis.

  • Free amino acid in ethanol extracts and total amino acids in hydrolysates of eleven species of edible mushrooms were analyzed and determinated the contents five kind of new amino acid by means of amino acid autoanalyzer and gas liquid chromatography. The result obtained from this study are as follows. 1) Five kind of new amino acid turned out to be ${\alpha}$-aminobutyric acid, allo-isoleucine, ethanolamine, $\gamma$-aminobutyric acid and ornithine. 2) By means of amino acid autoanalyzer, the monoethanolamine was identified on the chromatogram ahead of alanine, ${\alpha}$-aminobutyric acid between peak of threonine and glycine, allo-isoeleucine between peak of valine and leucine, isoleucine, ${\gamma}$-aminobutyric acid followed by proline between peak of leucine, isoleucine and methionine and ornithine between peak of phenylalanine and tyrosine 3) By means of Gas liquid chromatography, the ${\alpha}$-aminobutyric acid was identified on the chromatogram between peaks of alanine and valine, allo-isoleucine between peaks of methionine and isoleucine, monoethanolamine followed by ${\gamma}$-aminobutyric acid between peaks of phenylalanine and ammonia, ornithine between the peaks of ammonia and lysine. 4) Of five amino acids which were identified, ornithine was the highest of its content in the mushroom extracts, and allo-isoleucine, ethanolamine, and ${\gamma}$-aminobutyric acid came next in decreasing order. 5) Also which were identified, ornithine was the highest of its content in the hydrolysates, and ${\alpha}$-aminobutyric acid, ${\gamma}$-aminobutyric acid, allo-isoleucine came next in decreasing order, ethanol extracts and hydrolysates of Auriculariaauricula-Judae(Fr.) $Qu\acute{e}l$ species didn't contain any of five kind of new amino acid. Ornithine also was the highest in the hydrolysates of ll mushrooms.

  • We isolated and confirmed two S-RNases, denoted as mpS1 and mpS2, from apple rootstock 'Marubakaido' (Malus prunifolia Borkh. Var. ringo Asami). These S-RNases contained and conserved five cysteine residues and two histidine residues, which are essential for RNase activity. The mpS1 showed high similarity to S5 (99.1%) of Malus spectabilis, whereas the mpS2 showed 99.5% nucleotide sequence similarity to S26 of (Malus ${\times}$ domestica) and 99.6% to S35 of (Malus sieversii) when compared with reported S-RNases. In amino acid sequences, the mpS1-RNase was almost similar to the S5-RNase of Malus spectabilis, and the mpS2-RNase was similar to the S35 of Malus sieversii, with only one bp being different from the S26-RNase of Malus ${\times}$ domestica. The 57 S-RNases of Malus species were renamed and rearranged containing the new S-RNases, as mprpS35 (mpS2) and mprpS57 (mpS1), for determining S-genotypes and identifying new alleles from apple species (Malus spp.).

  • Capparis pubifolia B. S. Sun is reported here as a new addition to the flora of Vietnam. It is morphologically allied to C. sikkimensis Kurz but differs due to the gray-yellow color of the hair of the twigs, having more secondary veins on the leaf, trichomes on both surfaces of the petal, and a globose shape of the fruit. Thus far, it was only reported in the Guangxi and Yunnan areas of China. A description, a line drawing and color photographs are provided for species identification. Furthermore, a comparison of the diagnostic characters with those of related species is made.

  • The introduced exotic species has often caused severe problems to the native ecosystem. One of such species is the freshwater fish gengorobuna (Carassius cuvieri) introduced from Japan. The first step to assess harmful effects of this species on the Korean freshwater ecosystem is to discriminate it from the most similar native crucian carp (Carassius auratus). Because traditional morphological identification often gives unreliable results due to their highly similar phenotype, a new more efficient method is needed. For this purpose, molecular markers produced by the efficient one-step PCR method using three primers (DDF, DDR and DDR1) were developed and tested in the present study. This molecular marker will play an important role in monitoring fish community of Korean freshwater ecosystem.
