  • Phenotypes of panicle, hull and seed of mutant rice (Oryza sativa L.) were characterized. Panicle mutants were classified in 4 groups with their internode length of main rachis, primary rachis, secondary rachis and pedicel. Hull and seed mutants were grouped into 12 based on their mutant characters in shape, size and color of seeds. These natural and spontaneous mutant collections showed distinct phenotypes to wild type rice. This might be useful for the identification of the functions of genetic factors in the Mendelian inheritance.

  • Ten species of Galatheoidea (squat lobsters), belonging to two families, were collected in the Korean exclusive economic zone: Galathea balssi Miyake and Baba, 1964, Galathea orientalis Stimpson, 1858, Galathea pubescens Stimpson, 1858, and Galathea rubromaculata Miyake and Baba, 1967 belonging to Galatheidae; Bathymunida brevirostris Yokoya, 1933, Cervimunida princeps Benedict, 1902, Munida caesura Macpherson and Baba, 1993, Munida japonica Stimpson, 1858, Munida pherusa Macpherson and Baba, 1993, and Paramunida scabra (Henderson, 1885) belonging to Munididae. The present study comprises the morphological description of these ten species, including drawings and color photographs, a brief review of their regional records, and a key for their identification. Although all species are common in Japanese waters, G. balssi, G. rubromaculata, B. brevirostris, C. princeps, M. caesura, and M. pherusa are new to Korean marine fauna.

  • Taxonomic studies in external morphology, principal component analysis and cluster analysis were conducted to understand the intraspecific relationship among three habitats (Jirisan, Odaesan and Ulleungdo) of allium voctorialis var. platyphyllum. External morphology such as bulb color, leaf blade length and width, petiole length, total leaf length, peduncle length, perianth lobe length and width, length of anther and filament were useful characters for identification of poplations in three habitats. The results obtained based on the principal component (Pc) analysis of treated 72 OTUs(included outgroup) were divided into three groups by the PC 1 ,2,3 and the sums of contributions for the total variance were 84.1%(PC1 51.0%, PC2 24.9% and PC3 8.2%, respectively). In cluster analysis by the UPGMA and Ward's methods , there was similarities in the compostion of clustered taxa, and only Ulleungdo population was distinctly identified from population of other two habitats.

  • A bactirium prohibiting the growth of fungus Botrytis cineria KT 433 was isolate and identified from soil. The isolated strain was gram positive, aerobic bacteria with cream color, round and mucoid. It showed ord form of 0.45$\times$1.1 ${\mu}{\textrm}{m}$ at the cultivated for 24 hrs and the ellipsoided endospore wer observed after culting for 72 hrs. The optimum growth temperature and pH wer 35$^{\circ}C$ and pH 5.0~8.0, respectively. It could assimilate daxtrin, maltose, glucose, mannose, ribose and collobiose as a sole carbon source. The isolated was confirmed to be a Bacillus sp. strain from the findings. The antibiotic from the isolated strain was stable up to 121$^{\circ}C$. The strain, especially, showed specific activity for mold and yeast. However, there was not significant antibacterial activity.

  • Aspicilia humida Lee is described as a new lichen-forming fungus from a wetland forest, South Korea. The new species is distinguishable from Aspicilia aquatica (Fr.) Körb., the most similar species, by the absence of prothallus, black disk without green color in water, olivebrown epihymenium, shorter hymenium, hymenium I + yellowish blue-green, wider paraphysial tips without a vivid pigment, smaller asci, smaller ascospores, and the presence of stictic acid. Molecular analyses employing internal transcribed spacer (ITS) and mitochondrial small subunit (mtSSU) sequences strongly support A. humida as a distinct species in the A. cinerea group. A surrogate key is provided to assist in the identification of all 28 aspicilioid species of Korea.

  • Edwardsiella (E) tarda belongs to the Enterobacteriaceae family and is a motile, gram-negative, rod-shaped, facultative anaerobe regarded as an opportunistic and food-borne pathogen in animals and humans. A 21-year-old male Eurasian brown bear (Ursus arctos arctos) died suddenly without any preliminary signs. Necropsy performed according to standard protocol revealed swollen abdomen with hemorrhagic congestions of the gastroenteric organs, ascites, and hemorrhagic exudates around the mouth. The liver showed discoloration, along with a severely swollen and multiple hemorrhages of the spleen, an elongated gallbladder, and a congested cortex and medullar lesion of kidneys. The stomach contained semi-liquid exudates and undigested chicken exuding a decayed odor. The stomach membranes were dark-gray in color with several cysts in the fundus lesions. Rod-shaped bacteria were found in the major organs by Giemsa staining, identified as E. tarda using a biochemical rapid diagnostic identification kit.

  • For over five millennia, humans have benefited from the valuable byproducts of Bombyx mori silkworms nourished on mulberry leaves and a multitude of potential applications remains available due to the diverse array of silkworm varieties. In this work, we discuss the utilization of Daehwangjam (DHJ), golden silk (GS), and Juhwangjam (JHJ), distinctive colored silks found in Korea, as chemosensors. These novel silks emit fluorescence under external stimuli and show a diminishing fluorescence intensity when exposed to HCl vapor. The considerable surface-to-volume ratio of these cocoons allows for the identification of 5 ppm, 300 ppm, and 3000 ppm HCl vapors through decreased fluorescence intensity. The results show the suitability of natural DHJ, GS, and JHJ for applications in biosensing applications.

  • 국내에서 육성된 자색배축을 나타내는 품종들의 콩나물 재배시 자색 발현을 조사하고 자색의 배축발현에 관련된 재배요인을 구명하여 자색배축 콩나물 품종을 콩나물 원료콩으로 확대하는데 필요한 기초자료를 제공하고자 시험을 실시하였다. 이에 배축색과 꽃색이 모두 자색인 콩나물 콩 15품종을 콩나물 재배기에서 재배하면서 콩나물 배축의 자색발현 정도를 조사하였다. 그 결과, 다채, 명주나물콩, 소백나물콩, 소진나물콩, 안평 및 조남 등 6품종은 자색이 발현이 되지 않았으나, 소원콩, 원황, 신화, 은하콩, 풍산나물콩, 팔도나물콩, 광안, 신강 및 장기 등 9품종은 자색이 발현되었다. 재배온도, 재배기간, 관수온도가 자색발현에 고도로 유의한 요인으로 작용하였고, 이들 간의 상호작용 효과도 통계적으로 고도로 유의한 것으로 나타났다. 또한, 콩나물 배축의 자색발현은 콩나물 재배환경에 영향을 받는 것으로 조사되었다. 재배온도에 따른 자색발현 개체비율은 재배온도 $17^{\circ}C$, $20^{\circ}C$, $23^{\circ}C$에서 32.4~34.2%의 비율을 보인 반면 $26^{\circ}C$에서는 17.2% 만이 자색을 나타내어, 재배온도가 제일 높은 시험구에서 자색발현이 가장 낮게 나타났다. 관수온도에 따른 자색발현 개체비율은 관수온도가 제일 낮은 $10^{\circ}C$에서 36%로 가장 많은 개체비율을 보였다. 그리고 관수온도가 높아질수록 자색발현 개체비율이 점차 감소하여 가장 높은 온도인 $26^{\circ}C$에서 가장 낮은 개체비율을 나타내었다. 재배기간에 따른 자색발현 정도는 재배 3일째에는 자색발현이 전혀 없었으나 4일째에 52%로 가장 높은 발현비율을 보였고 5일째에는 감소하여 36%의 개체가 자색배축을 나타내었다.
