부성민,이인규 ( Sung Min Boo,In Kyu Lee ) 한국환경생물학회 1984 환경생물 : 환경생물학회지 Vol.2 No.1

Two Korean species of Spyridia J. Agardh are investigated taxonomically. Spyridia filamentosa (Wulfen) Harvey collected at Wando-Islands in the southern coast is characterized by its regularly arranged internodal and nodal cells. S. elongata Okamura collected at Kangreung in the eastern coast is characterized by its irregularly arranged internodal cells and small fusiform branches around the axis. The latter species, collected for the first time in Korea, is very similar to S. squalida J. Agardh from the Southern Australia. Some important taxonomic characters of the two species are summarized.

보령 지역의 산간 계류에서 식물플랑크톤의 계절 변화

부성민,김준태,조현실,신웅기 ( Sung Min Boo,Jun Tae Kim,Hyun Sil Cho,Whoongghi Shin ) 한국하천호수학회 1997 생태와 환경 Vol.30 No.2

The seasonal changes of the phytoplankton in the mountainous streams around Boryong were investigated at the four stations from May 1995 to November 1996. A total of 146 phytoplankton species were identified, of which most of them belonged to the diatoms and the green algae. The mean standing crops of phytoplankton was high with 1,725 cells/ml in May and 1,064 cells/ml in July 1996, of which the diatom standing crops was the highest. Cymbella tumida, Melosira varians, Navicula viridula, and Synedra ulna predominated in the mountainous streams around Boryong and showed an unimodal pattern in the seasonal changes of standing crop. Our results show that a typical phytoplankton community of the mountainous streams occurs in the streams around Boryong.

홍조 (紅藻) Antithamnion sparsum Tokida 의 생활사 및 교배에 관한 연구

부성민(Sung Min Boo),이인규(In Kyu Lee) 한국식물학회 1983 Journal of Plant Biology Vol.26 No.3

Antithamnion sparsum Tokida isolated from the southern and western coasts of Korea was investigated in culture, comparing the morphological character with A. defectum Kylin from the Pacific North America. A. sparsum basically showed a Polysiphonia-type life history. However, it sometimes exhibited a monoecious reproduction and the carpospores released from the cystocarp by self-fertilization unexpectedly developed into the plants bearing spermatangia alone. These male plants were not functional up to 60 days culture. The results of intraspecific crosses between populations of A. sparsum were positive and the hybrid carpospores gave rise to normal tetrasporophytes. On the other hand, the interspecific crosses between A. sparsum and A. defectum were successful partly, evidenced by the gonimoblast development and the release of carpospores in case of A. sparsum (male) × A. defectum (female), but not in case of A. sparsum (female) × A. defectum (male). Thus, the both species were still under the speciation.

한국산 은방울꽃 ( Convallaria majalis ) 의 형태적 특징과 핵형분석

부성민(Min Boo Sung),윤환수(Hwan Su Yoon),민병미(Byeong Mee Min),방재욱(Jae Wook Bang) 한국환경생물학회 1999 환경생물 : 환경생물학회지 Vol.17 No.3

Morphology and karyotype of Korean Convallaria majalis plants were observed for taxonomic studies. Most plants produced two leaves(70%) and some one leaf(30%), but rarely three leaves. Plant length averaged 34.4±4.6㎝. Percentage of plants bearing flowers was very low with 3.7% (n=1.346) in the field. Raceme usually grew below leaves and rarely grew over leaves. Plant beared five to ten flowers on a single raceme. Chromosomes were x=19 and diploidy with 2n=38. The chromosomes were composed of 13 pairs of median and 6 pairs of submedian chromosomes. The number of chromosome and karyotype of Korean C. majalis plant agree with those of Japanese and European plants. [Convallaria majalis, chromosome, karyotype, morphological variation, taxonomy].

홍조 (紅藻) Ceramium fastigiatum Harvey 의 분류학적 재검토

부성민(Sung Min Boo),이인규(In Kyu Lee) 한국식물학회 1985 Journal of Plant Biology Vol.28 No.3

Because Ceramium fastigiatum Harvey(1834) is a later homonym of C. fastigiatum Roth(1806), a quite different plant from the former, it becomes illegitimate and must be rejected under the Article 64 of International Code of Botanical Nomenclature. For this reason, we suggest to give a new name, Ceramium fastigiramosum Boo et Lee, to the former species, keeping the original specific epithet `fastigiatum`. The morphology of vegetative and reproductive structures is re-examined. The life history is confirmed as a Polysiphonia-type in laboratory culture.

한국산 홍조 (紅藻) Centroceras 속 (屬) 이종 (二種)

부성민(Sung Min Boo),이인규(In Kyu Lee) 한국식물학회 1985 Journal of Plant Biology Vol.28 No.4

Two Korean species of Centroceras Ku¨tzing, Ceramiaceae was investigated taxonomically. C. clavulatum (Ag.) Montagne collected at several sites along the coast of Korea was characterized by regular dichotomous branches with whorl spines at every node, whereas C. distichum Okamura collected at Soando in the southern coast was by alternate branches with gland cells around nodes. Biogeographic data show that Korea is almost northern limit in distribution of the former species.

한국산 홍조 (紅藻) Antithamnionella miharae ( Tokida ) Itono

부성민(Sung Min Boo),이인규(In Kyu Lee) 한국식물학회 1985 Journal of Plant Biology Vol.28 No.3

Antithamnion miharae(Tokida) Itono was investigated in field and laboratory culture. The plant grows in lower littoral zone through out the year in Korea. The gland cells occur scarcely or commonly according to the populations, but the terminal hairs in the female plants are not observed. The structure of vegetative thallus and the reproductive organs in culture are similar to those of field materials, except for the number of gonimoblasts, wich become five to six in contrast to one to three of the field. A typical Polysiphonia-type life history is repeated in culture. This species which produces tetrahedral tetrasporangia is markedly distinguished from Antithamnion glandulifera sensu Kylin (=Antithamnionella glandulifera (Kylin) Wollaston) which produces cruciate tetrasporangia, while the plants reported by Dawson (1962) and Wollaston(1971) as A. glandulifera seem to be conspecific with A. miharae by the fact that they have the tetrahedral tetrasporangia in stead of cruciate ones.

First Record of Scytosiphon gracilis Kogame (Scytosiphonaceae,Phaeophyceae) for the Pacific coast of Mexico

조가윤,부성민,Raul, Aguilar-Rosas,Luis E., Aguilar-Rosas,Cho, Ga-Youn,Boo, Sung-Min 한국조류학회(藻類) 2006 ALGAE Vol.21 No.1

In this work we report the occurrence of Scytosiphon gracilis Kogame (Scytosiphonaceae, Phaeophyceae) on the Pacific coast of Mexico. This is the first report of S. gracilis outside its previously known distribution in the western North Pacific (Korea and Japan). The identification was based on a morphological revision and a comparison of the plastid-encoded RuBisCO spacer sequences determined for Korean and Mexican algal material. Thalli were collected from the intertidal zone of Saldamando Beach, Baja California, in January 2003. The vegetative structure, as well as habitat and geographic distribution of the species are described. Reproductive structures were not found in our specimens. The poor presence/absence of S. gracilis in previous floristic studies of the area could be due to its small size and low frequency.

Molecular phylogeny of the Family Scytosiphonaceae (Phaeophyceae)

조가윤,부성민,Jo, Ga-Youn,Kogame, Kazuhiro,Boo, Sung-Min The Korean Society of Phycology 2006 ALGAE Vol.21 No.2

Recent phylogenetic studies of scytosiphonacean brown algae show many conflicts with current classification. In order to clearly define the phylogenetic relationships of the family, we newly sequenced the photosystem I coding psaA gene (1488 base pairs) from 13 taxa (15 samples), of the family, and, for comparison, rbcL from four taxa. The psaA region has more informative sites (17.9%) than the rbcL (13.1%) and the number of nodes supported by over 50% bootstrap values is more in the psaA phylogeny (53 /57 nodes; 93%) than in the rbcL (47/63 nodes; 74.6%). The psaA phylogenies are basically congruent with the rbcL trees, recognizing two major groups in the monophyletic Scytosiphonaceae. The first group included Myelophycus, Petalonia, Scytosiphon, and elongate sack-shaped species of Colpomenia, primarily cold temperate elements with unilocular zoidangia on sporophytes. The second group, although not resolved, consisted of Hydroclathrus, Chnoospora, Rosenvingea, and ball-shaped Colpomenia, primarily warm-temperate taxa with both unilocular and plurilocular zoidangia on sporophytes. Chnoospora is not monophyletic, as was previously shown the paraphyly of Colpomenia, Petalonia, and Scytosiphon. Hydroclathrus clathratus from Korea and Japan was not monophyletic. Our studies show that gametophytic characters are the main source of conflict for the present taxonomy of the family. The psaA region is a useful tool for resolution of phylogenetic relationships within the Scytosiphonaceae.

갈조식물 Endarachne binghamiae J. Agardh 의 동해안에서의 형태적 변이

유경식(Kyeong Sik Rhew),부성민(Sung Min Boo) 한국식물학회 1991 Journal of Plant Biology Vol.34 No.1

Morphological variability was quantified for Endarachne binghamiae J. Agardh from five local populations collected in December, 1989 and in March, 1990. The sampling sites were chosen at intervals of 50`N along the east coast of Korea. Fifty individuals were haphazardly collected for the relationship between the blade length and reproduction, among which twenty five individuals were randomly selected for morphological variation. The Korean plants of E. binghamiae had the capacity of reproduction at an early stage of growth. The holdfast diameter and the plurangial length showed clinal variation of increment from the north to the south whereas the cryptostomata from the south to the north. The holdfast diameter, the blade thickness, the number of plurangial blades and the cryptostomata increased from December to March, when the blade length decreased. Endarachne is distinguished by the densely interwoven hyphal cells in the medulla. four to eighteen rows of the plurangial compartments, and absence of paraphyses between plurangia. Therefore E. binghamiae should not be combined into Petalonia, but rather the Soviet plants of P. zosterifolia may be renamed as a taxon belonging to the genus Endarachne.
