충북 보은군 임하리에서 우리나라 물옥잠과의 미기록 분류군, 가는물달개비(물옥잠과)가 새로이 발견되었다. 이 분류군(Monochoria vaginalis var. angustifolia)은 물옥잠속의 다른 분류군에 비해서 식물체가 작고, 잎이 매우 가는 피침형, 잎의 기부가 쐐기형이고, 1-2개의 적은 꽃이 달린 총상화서이고, 꽃대의 길이가 작은 점에서 뚜렷이 구분된다. 국명은 잎이 가는 특징을 고려하여 '가는물달개비'로 신칭하였고, 주요형질에 대한 분류군의 기재 및 종의 해부도와 서식지 식물사진을 제시하였고, 아울러 한국산 물옥잠속 식물에 대한 검색표를 제시하였다.

Aster altaicus var. uchiyamae Kitam. is an endemic taxon of Korea and is protected by law as an endanger taxon. The genetic information of A. altaicus var. uchiyamae is unavailable in Genbank. Here we sequenced chloroplast genome of A. altaicus var. uchiyamae. The cp-genome of Aster altaicus var. uchiyamae was 152,446 bps in size: LSC was 84,240 bps, IR 25,005 bps, SSC 18,196 bps. The cp-genome contains 112 genes and 21 introns consisted of 79 protein coding genes(PCGs), 4 RNA genes, and 29 tRNA genes, with 20 group II introns and one group I intron. There were three pseudo-genes including ${\psi}$-ycf1, ${\psi}$-rps19, and ${\psi}$-trnT_GGU. Eighteen genes, five introns, and parts of two genes and an intron are found within the IR, which has two copies. The cp-DNA of Aster altaicus var. uchiyamae is distinguished from A. spathulifolius, only known cp-genome of the genus Aster, by 172 SNP in genic regions of 43 PCGs and 21 indels in 11 PCGs and SSU. The chloroplast genome sequence was deposited at GenBank (KX35265).

The essential oils were isolated by hydrodistillation and their composition determined capillary GC method with standards. The essential oil content showed significant differences between the two populations on the vegetative organs. The essential oil level of the leaves and roots was considerably higher in the Korean population at full flowering and waxy ripening stage but essential oil content of the roots was significantly higher in the Hungarian taxon at leaf rosette stage. We observed the essential oil accumulation tendency was mianly dependent on plant organs and intra-specific taxon during the vegeation period. Butylidene-phthalide was proved to be the main component of the oil in both population roots (50.9-73.3%), while dimethyl-acetate was showed as a major compound on the over-ground parts (56.7-62.0%). The qualitative composition of the essential oil in the reproductive organs concerning the identified compounds was the same as the vegetative parts with the main component ${\alpha}-phellandrene$ (4.8-28.1%) and butylidene-phtalide (9.7-16.1%), The quantitative composition showed some changes during the ontogenesis phases. Most characteristic ones are the decreasing proportion of dimethyl-acetate (from 7.3% to 1.1%) and the appearance of ${\alpha}-pinene$ (from 0.5% to 1.5%) only after fruit setting in both population.

A holotype is an element to which the name of a taxon is permanently attached and is key material that facilitates taxonomic research. However, type citation or designation errors due to typographical errors or inadvertent mistakes often exist. When reviewing recently published literature for the type specimens of vascular plants in the herbarium of the National Institute of Biological Resources, we observed that three species, Isoetes laosiensis, Isoetes coreana, and Huperzia jejuensis, had errors, and the actual holotype information and the type descriptions of the protologues did not match. The name Isoetes laosiensis had a collecting number error, while Isoetes coreana and Huperzia jejuensis had collector errors. According to Article 9.2 of the International Code of Nomenclature for algae, fungi, and plants (Shenzhen code), if a holotype designation in the protologue of the name of a taxon is found to contain errors such as collector, collecting number, and illustration errors, the errors are to be corrected. We, therefore, corrected the errors in holotypes of three species, with no alterations made to the intents of the original authors.

중국 연변지역에서 할미꽃속의 신잡종인 연변할미꽃(Pulsatilla ${\times}$ yanbianensis H.Z. Lv)을 새로이 발견하여 기재하였다. 연변할미꽃은 개화시 잎이 완전히 벌어져 분홍할미꽃과 유사하나, 꽃받침이 적자색이고 과실이 불임인 점에서 뚜렷이 구별된다. 연변할미꽃은 꽃받침과 화주가 흑적색인 가는할미꽃과 유사하나, 잎의 엽연에 짧은 털이 있고 개화시 잎이 완전히 벌어진 점에서 뚜렷하게 차이가 난다.

In order to compare species-specific calcium metabolism, we collected 127 species belonging to 40 different families grown on various habitats including saline, limestone, wetland during the 1996 vegetation period, and analyzed their inorganic ion contents. Plants investigated were divided into 5 groups according to their physiological properties: 1) Chenopodiaceae, Aizoaceae, Caryophyllaceae, Portulacaceae and Phytolaccaceae of Centrospermales and Polygonaceae (Polygonales had a little water-soluble $Ca^{2+}$ but contained high contents of insoluble $Ca^{2+}$ particularly as Ca-oxalate (Chenopodiaceae type), 2) Some plant species such as Rosaceae produced oxalate in amounts insufficient to precipitate all incoming $Ca^{2+}$ and thus contained a surplus of dissolved $Ca^{2+}$ (Rosaceae type), 3) The contents of water-soluble $Ca^{2+}$ in plant species of Crassulaceae. Plantaginaceae, Asclepiadaceae, and Zygophyllaceae were equal to or greater than those of K ($K/Ca{\leq}1$; Crassulaceae type), and 4) K/Ca ratios of Compositae were significantly fluctuated depending on species and soil $Ca^{2+}$ level of their habitats (Compositae type). 5) Certain monocots (Gramineae, Cyperaceae, Juncaceae), in contrast to the dicotyledonous plant families mentioned above, showed a very distinct type of calcium metabolism, that is, the K/Ca ratios of 8~10 were maintained indifferently in the species and their habitat types (Graminae type). These results plants within the same taxon have similar physiological aspects as weel as morphological attributes. To understand calcium metabolism of certain plant species, therefore, it is desirable to approach on the basis of physiological concept (calciotroph or calciophobe) rather than the ecological one (calcicole or calcifuge).

biotic indices scoring with the benthic macroinvertebrates were assessed as pollution monitoring tools in the north branch of the Han River system, Korea. We investigated the temporal variability of water quality at unpolluted, moderately polluted and heavily polluted sites using several biotic indices and assessed appropriate biological monitoring indices for lotic systems in Korea. The following biotic and chemical indices were employed in order to compare their applicability to the lotic systems : Trent Biotic Index (TBI), Chandler's Biotic Index-Average Score per Taxon (CBI-ASPT), Modified Biological Monitoring Working Party Score System-Average Score per Taxon (BMWP-ASPT), Hilsenhoff's biotic Index (BI) and Family-level Biotic Index (FBI) models for biotic analyses and National Sanitation foundation's Water Quality Index (NSFWQI) and comprehensive Chemical Pollution Index (Pb/n) for chemical analyses of water quality. Index and score values were compared with each other and with 24 water chemistry parameters. All biotic indices were significantly auto-correlated (p<0.001) and BI and FBI/ROK among them were highly correlated (r=0.84). BI and BMWP-ASPT models were also highly correlated with NSFWQI, while TBI values showed high correlation with the Pb/n. The BI and BMWP-ASPT were highly correlated with the most water chemistry parameters. We conclude that the BI model, which includes indicator species and abundance of taxa, is best suited for the bioassessment of lotic systems in Korea. For rapid field-based assessments, FBI/ROK and BMWP-ASPT models are also appropriate.

한반도 중부의 강원도 정선군 금대봉에서 채집된 용담과 수염용담속의 1분류군-꼬인용담-을 한반도 미기록종으로 확인하였다. 본 분류군은 인도, 네팔, 파키스탄 등 히말라야 산악지대에 주로 분포하며, 또한 중국 및 일본 일대에도 생육하는 것으로 알려져 왔다. 형태학적 형질을 근거로 분류군에 대한 기재를 수행하였으며, 국명을 꽃의 형태적 특징을 고려하여 '꼬인용담'으로 하였다. 또한 주요 형질에 대한 도해도와 근연식물과의 차이점을 검색표로 제시하였다.

이전에 부탄으로부터 알려진 은대난초속(난과)의 민은난초 (Cephalanthera erecta var. oblanceolata N. Pearce & P. J. Cribb)가 경기도 화성시 서신면 전곡리의 저지대에서 발견되었다. 이 식물은 등꽃받침과 곁꽃잎이 도피침형이며, 곁꽃받침이 피침형이고, 거가 없는 단순한 꽃잎모양의 입술꽃잎에 의하여 은난초와 구별된다. 국명은 거가 없는 입술꽃잎을 갖는데 근거하여 민은난초로 신칭하였다. 민은난초의 형태적 특징과 도해를 사진과 함께 제시하였다.

Banana planting altered microbial communities and induced the enrichment of Fusarium oxysporum in rhizosphere compared with that of forest soil. Diseased plant rhizosphere soil (WR) harbored increased pathogen abundance and showed distinct microbial structures from healthy plant rhizosphere soil (HR). The enriched taxon of Bordetella and key taxon of Chaetomium together with some other taxa showed negative associations with pathogen in HR, indicating their importance in pathogen inhibition. Furthermore, a more stable microbiota was observed in HR than in WR. Taken together, the lower pathogen abundance, specific beneficial microbial taxa and stable microbiota contributed to disease suppression.
