The zoantharians and ceriantiparians known from the Korea Strait are 21 species, 16 genera, 10 families in 3 orders, of which 6 species are newly recorded to the Korea Strait fauna. Three species of them are new to Korean waters: Flosmaria mustsuensis, Hormathia andersoni and Verrillactis paguri. The specimens were collected from 34 localities of Korea Strait from 1984 to 1991.

비짜루과 둥굴레속(Asparagaceae: Polygonatum)은 전 세계적으로 약 90여 종이 알려져 있으며, 유럽, 북아메리카, 아시아 등 북반구 온대 지역에 집중적으로 분포한다. 국내 둥굴레속 분류군은 총 16분류군이며, 이중 잎이 호생하고, 난형에서 타원형 모양의 엽질성 포를 가지며, 화피통 내부에 털이 없고, 수술대 표면에 돌기가 나있는 분류군들은 용둥굴레열(series. Bracteata)에 속한다. 그러나 이들은 종간 교잡 또는 주요 기관의 형질 변이가 다양하여 중간형질을 보이는 개체군들에 대한 종 식별에 많은 어려움이 있었다. 경남 창원시에서 채집된 목포용둥굴레(P. cryptanthum) 변이 개체집단는 기존의 목포용둥굴레와 달리 식물체 높이와 화경·소화경이 길며, 포 부착위치의 변이 폭이 넓으며, 포가 타원형이고 밖으로 말리는 습성으로 형태적 차이가 나타났다. 따라서 본 연구에서는 명확한 분류학적 실체를 구명하고자 분자생물학적 계통분석(nrDNA ITS + cpDNA matK, trnK-rps16, rps16, rbcL) 연구를 진행중에 있다.

한국화합물은행(KCB)에서 보유중인 12만 개의 화합물을 주요 골격에 따라 분류하고, 4 가지 protease 작용점에 대한 활성도와 골격사이의 관계를 조사하였다. 화합물들은 합성기관의 합성 목적과 주요 고리골격 등을 고려하여 분류되었으며, 이를 이용하여 scaffold 분류를 위한 분류 계통도를 작성하였다. 화합물들은 이 계통도에 따라 7 가지의 race, 168 tribe, 493 parent, 439 child, 325 grandchild 등 1,087개의 scaffold로 분류되었으며, 각 race 및 scaffold 별 골격의 개수는 고르게 분포되었다. 골격별 분류 시스템을 이용하여 4 가지의 protease에 대한 활성도와 골격 간의 상관관계를 조사한 결과, Protease C에 대하여 몇 가지 골격이 활성이 뛰어남을 보였다.

The sequence data of the plastid DNA (trnL-F IGS, trnL intron, and trnH-psbA) and nuclear DNA (RNApol2_i23) markers were utilized to study phylogenetic relationships among the taxa in the Polygonatum odoratum complex (Ruscaceae). European P. odoratum individuals form a clade with a high bootstrap value, which is a sister to the clade of Korean P. odoratum var. odoratum, P. odoratum var. pluriflorum and P. robustum. The formation of the clade with P. odoratum var. odoratum, P. robustum, and one accession of P. odoratum var. pluriflorum indicates geological speciation in isolated populations in the islands following dispersal events from the mainlands. All data sets form two major clades, which are congruent with the subgroups divided by the basic chromosome numbers (x = 9 and x = 10). Although it is not easy to test the hypothesis of the decrease in the basic chromosome number due to scatter taxon sampling in this study, the molecular data strongly suggested that aneuploidy plays an important role in lineage diversification in the genus Polygonatum. The cytological data was not strongly supported by the cpDNA sequences. Further investigations of the cytological, morphological, and geographical characteristics with comprehensive sampling are desired to understand the evolution and lineage diversification in the genus.

The snailfishes (Scorpaenoidei: Liparidae) is a large group requiring taxonomic reviews because of a potential taxonomic confusion due to its great similarity in external morphology between species and a variation of its body color with size. Molecular phylogeny and taxonomic review were conducted for 10 species in 3 genera reported around the Korean waters, which facilitate understanding interrelationship within its family, and further management of fisheries resources. Molecular phylogeny using mitochondrial COI (mtCOI) and nuclear RAG2 (nRAG2) sequences indicates that the reciprocal monophyly of the three genera (Careproctus, Crystallichthys, and Liparis) were supported except Crystallichthys matsushimae, being closely related to Careproctus notosaikaiensis in only mtDNA COI topology. Liparis ingens Gilbert and Burke (1912) was reported as a distinct species differing from L. ochotensis. However, in the present study, comparing L. ingens from Korea with L. ochotensis from Japan and Russia, the two species were well corresponded in their morphology and molecule, therefore, we suggest L. ingens to be treated as a junior synonym of L. ochotensis.

One hundred and three isolates of Xanthomonas oryzae pv. oryzae in Korea were evaluated for their virulence on four near-isogenic lines (NILs) containing a single resistance gene, and Korean differential varieties. The resistant gene backgrounds of Cheongcheongbyeo, Pungsanbyeo, Hangangchalbyeo, Milyang42 were not completely understood and they were not suited for the classification of X. oryzae pv. oryzae. Four NILs, IRBB101, IRBB103, IRBB105, and IRBB107 were difference for characterizing races of X. oryzae pv. oryzae because they have a single resistance gene. These NILs may be useful differential set in examining pathogenic races of X. oryzae pv. oryzae in Korea. Based on the virulence of 103 isolates to new differential varieties, they were classified into 3 races.

This study was carried out to identify the phylogenetic relationship and to know the distribution of the entomopathogenic fungi by comparing the DNA sequences of internal transcribed spacer regions (ITS1 and ITS2) and 5.8S ribosomal DNA (rDNA) repeat unit. The entomopathogenic fungi had their specific sequences in ITS1 and 2 regions depending on species. The comparison of the ITS sequences of standard strains indicated that the sequences ITS1 were more variable than those of ITS2. It seems that Paecilomyces tenuipes, Isaria japonicus and P. japonicus are the same species but called as different names because of very similar sequences, and unidentified Paecilomyces sp. KACC 40220 and KACC 40656 showed identical sequences to P. tenuipes. Thirty six strains of the commercial products of entomopathogenic fungi used in this study were divided into four groups by the phylogenetic analysis based on 5.85 rDNA and ITS regions. We found twenty-three strains were P. tenuipes / japonica, eleven strains were C. militaris, and other two strains were Beauveria bassiana and C. multiaxialis, respectively.
