노루오줌속(Astilbe)은 동아시아와 북미 동부에 격리되어 분포하는 양상을 보이는 속으로 잘 알려져 있다. 본 연구에서는 노루오줌속 및 근연 속을 대표하는 17종의 핵 리보솜 DNA의 ITS 염기서열에 기초한 계통수를 제작하여 노루오줌속의 분류, 형질 진화 및 계통지리에 대하여 고찰하였다. 베이스 추론법 등을 통해 계통수를 제작한 결과 Saxifragopsis가 노루오줌속의 자매군임이 확인되었고, 단성화, 무화피화, 7~11개로 갈라지는 꽃받침 등의 형질상태를 지니는 것으로 알려진 일본 고유종, A. platyphylla는 노루오줌속 계통수의 기부에서 가장 먼저 분리되었다. 북미에 격리 분포하는 분류군인 A. biternata 및 중국과 동남아시아에 분포하는 A. rivularis는 노루오줌속의 진화 초기에 갈라진 것으로 밝혀졌다. 한편, 화피가 있는 나머지 종들은 하나의 핵심군으로 확고하게 무리를 지었다. 핵심군 내에서는 일본, 대만, 필리핀 등지에 분포하는 종들("Japonica" clade) 이 단계통군을 이루었고, 중국 및 한국에 분포하는 종인 A. rubra var. rubra(노루오줌)과 A. koreana(숙은노루오줌), 즉 "Rubra" clade는 이들과 명확히 구분되는 진화 계열로 나타났다. A. biternata의 기원과 격리분포는 베링육교(Bering land bridges)를 통해 이루어진 것으로 추정되었다. 대만에 분포하는 2종과 A. philippinensis는 일본에 분포하는 분류군이 남하하면서 갈라져 나온 것으로 해석되었다. 노루오줌속 내에서 무화피화는 원시적 형질상태였으며, 이 형질상태는 적어도 두 개의 진화 계열에서 각각 독립적으로 기원하였을 것으로 추정되었다. 본 연구결과는 노루오줌속을 분류함에 있어서 잎의 유형(단엽/복엽)을 중요시했던 Engler의 분류 체계를 지지하지 않았으며, 꽃받침의 형태를 일차적으로 고려했던 Hara의 분류 견해를 지지하였다.

Given the lack of a resistant genetic pool in host plants, the introduction of exotic invasive pathogens can result in epidemics that affect a specific ecosystem and economy. Plant quarantine, which is designed to protect endemic plant resources, is a highly invaluable safeguard that should keep biosecurity with increasing international trade and global transportation. A total of 34 species of plant pathogens including Phytophthora infestans were documented as introduced from other countries into Korea from 1900 to 2010. The genus Phytophthora, classified in oomycetes, includes more than 120 species that are mostly recognized worldwide as highly invasive plant pathogens. After 2000, over 50 new species of Phytophthora were identified internationally as plant pathogens occurring in crops and forest trees. In Korea, Phytophthora is also one of the most serious plant pathogens. To date, 22 species (about one-fifth of known species) of the genus have been identified and reported as plant pathogens in the country. The likelihood of new exotic Phytophthora species being introduced into Korea continues to increase, thus necessitating intensive plant quarantine inspections. As new potential threats to plant health in Korea, six Phytophthora species, namely, P. alni, P. inundata, P. kernoviae, P. pinifolia, P. quercina, and P. ramorum, are discussed in this review with focus on history, disease, biology, management, and plant quarantine issues.

Aruncus L. is a small genus which is distributed in the circumpolar regions of the Northern Hemisphere, including Europe, Asia, and North America. In Korea, there are two taxa, A. dioicus var. kamtschaticus and A. aethusifolius. Aruncus aethusifolius is a species endemic to Korea, occurring only on Jeju Island. An important characteristic of Aruncus is dioecy. However, there is some controversy regarding the sexuality of this genus, and little is known about A. aethusifolius. To characterize the sexuality of A. aethusifolius and to provide insight into the evolution of its sexual system, we investigated natural populations and herbarium specimens of A. aethusifolius. The results indicate that the species has carpellate, staminate, and bisexual flowers. Carpellate flowers are always borne on separate individuals, and staminate flowers are borne either on separate individuals or mixed with bisexual flowers on the same individuals. The sexuality of A. aethusifolius is defined as polygamo-dioecious. The polygamo-dioecious type is also found in A. dioicus var. dioicus and A. dioicus var. kamtschaticus and thus may be a general condition in Aruncus.

The vascular plants in Jeju composed of 21 families 62 genera, 190 species, 7 varieties with 197 taxa in Pteridophyta, 3 families 5 genera, 7 species, 3 forma with 10 taxa in gymnosperm (Coniferophyta) and 143 families 703 genera, 1,622 species, 114 varieties and 47 forma with 1,783 taxa in Endospermae. The total number of taxa was 1,990 consisting 167 families, 770 genera, 1,818 species, 121 varieties and 50 forma. Three families, 4 genera 4 species and 1 variety in Pteridophyta and 1 family, 1 genus I species, 1 forma of Coniferophyta were endemic to Jeju. Five families, 8 genera and 8 species in the Monocotyledonae of Endospermae and 23 families, 32 genera, 21 species, 16 varieties and 7 forma and 44 taxa in Cholipetalae, and 9 families, 24 genera, 12 species, 13 varieties and 7 forma, total 32 taxa in Sympetalae were endemic to Jeju. Total 90 taxa with 41 families, 69 genera, 46 species, 29 varieties and 15 forma were drawn up as endemic plants in Jeju. As the numbers show on, Jeju has more biodiversity especially plant diversity than any other places in Korea. It was an important region in regard to geographical position. The rarity on plants from Jeju has been assessed based on the IUCN red list categories and criteria at both regional and global levels. There was one species in each extinct (EX) and extinct in the Wild (EW). The EX and EW species were Rhododendron saisiuense Nakai (Ericaceae) and Asplenium antiquum Makino (Aspleniaceae), respectively. Three taxa, Rhododendron dauricum L. (Ericaceae), Lycopodium sieboldii Miq., and Lycopodiella cernua (L.) Serm (Lycopodiaceae) were species that is extinct in the region (RE). Sixty-one taxa were critically endangered (CR), 13 were endangered (EN), and 83 were vulnerable (VU) at regional level. The taxa listed on a Red List corresponds 26.9% of total taxa in Jeju. At global level, there were 19 taxa in CR, 4 in EN, and 1 in VU (Vulnerable) as the category of threat. The rest taxa (133 taxa) were classified as Least Concern (LC). According to the results of the assessment, conservation measures must be taken for total of 157 species that were categorized in threaten including one of EX, one of EW and three extinct in the region immediately. Of 157 species, 61 were CR, 13 are EN and 83 were VU.

Malaria is a tropical disease caused by protozoans of the Plasmodium genus. Delayed diagnosis and misdiagnosis are strongly associated with higher mortality. In recent years, a greater importance is attributed to Plasmodium knowlesi, a species found mainly in Southeast Asia. Routine parasitological diagnostics are associated with certain limitations and difficulties in unambiguous determination of the parasite species based only on microscopic image. Recently, molecular techniques have been increasingly used for predictive diagnosis. The aim of the study is to draw attention to the risk of travelling to knowlesi malaria endemic areas and to raise awareness among personnel involved in the therapeutic process.

Abeliophyllum distichum Nakai belonging to Oleaceae is only species in Korean endemic genus, Abeliophyllum. Abeliophyllum distichum (AD) is divided into various types according to flower shape and color. AD is known to have various colors such as white, pink, and ivory. Recently, light yellow flowers have been registered as new varieties (Okhwang 1ho). To date, various ecological and morphological studies on AD have been carried out, but no studies have been made on the phytochemicals and activities according to various traits. In this study, we analyzed the phytochemicals and antioxidative activities of from four kinds of flowers (white, pink, ivory, light yellow) in full bloom. The contents of phytochemicals such as chlorogenic acid, Hirsutrin, Rutin, Acteoside and Isoacteoside were analyzed by HPLC. Antioxidant activity was evaluated by DPPH, ABTS. As a result, the content of each substance varied according to the flower color. These results will provide basic data for evaluating the usefulness of genetic resources in Korea and developing new functional materials in preparation for the Nagoya Protocol.

The subgenus Idioglochina Alexander, 1921 belongs to the genus Dicranomyia Stephen, 1829 and has a special habitat unlike other congeners. The larval stage inhabits marine algae near the intertidal zones. The most distinctive characters are found in the antennae with inner face of flagellar segments extended to produce a serrate form. A total of 30 species of the subgenus Idioglochina are recorded with the distribution is restricted to the Pacific and Indian Ocean regions. In this study, the subgenus and its species D. (I.) tokara (Nobuchi, 1955) are newly added to the Korean fauna. This species was previously recorded in Japan as an endemic species, but it was collected from Jeju Island. A redescription, period of activity, habitat information, and photographs of diagnostic characters of the species are provided. The female ovipositor is photographed for the first time.
