This study presents a survey of bryophytes in a subtropical forest of Nabeup-ri, known as Geumsan Park, located at Aewol Gotjawal in the northwestern part of Jejudo Island, Korea. A total of 63 taxa belonging to Bryophyta (22 families 37 genera 44 species), Marchantiophyta (7 families 11 genera 18 species), and Anthocerotophyta (1 family 1 genus 1 species) were determined, and the liverwort index was 30.2%. The predominant life form was the mat form. The rates of bryophytes dominating in mesic to hygric sites were higher than the bryophytes mainly observed in xeric habitats. These values indicate that such forests are widespread in this study area. Moreover, the rock was the substrate type, which plays a major role in providing micro-habitats for bryophytes. We suggest that more detailed studies of the bryophyte flora should be conducted on a regional scale to provide basic data for selecting indicator species of Gotjawal and evergreen broad-leaved forests on Jejudo Island.

Recently, it has become known that Gotjawal terrain is an important area, therefore the study on this area has conducted in the geological, ecological, and cultural aspects. The studies on bryophytes of Gotjawal, however, have not been sufficiently performed. This study presents a survey on the bryophytes of the evergreen broad-leaved forest of Cheongsu-ri at Hangyeong Gotjawal in the southwestern part of Jejudo Island, Korea. A total of 72 taxa belonging to the Bryophyta (18 families 43 genera 55 species) and Marchantiophyta (11 families 13 genera 17 species) were determined and the liverwort index was 23.6%. Predominant life-form was weft. The rates of the bryophytes dominating in mesic to hygric sites were higher than the bryophytes mainly observed in xeric habitats. These values indicate that the forests are widespread and dense in this study area. Upon an investigation of the substrates, the bryophytes on rocks were most diverse. The results appear to stem from the fact that volcanic rock masses of various sizes lay scattered over the study area, offering numerous micro-habitats for bryophyte due to one of the characteristics of Gotjawal. We suggest that more detailed studies should be conducted at the regional scale to establish the bryophyte flora of Gotjawal and the evergreen broad-leaved forests on Jejudo Island.

Dichlororinated bibenzyl compound (4) has been isolated from the New Zealand liverwort. This compound was elucidated using 1D/2D-NMR and mass spectral method. The compound (3) inhibited the growth of the Gram positive bacterium Bacillus subtilis ATCC 19659, (2 mm inhibition zone and 2 mm inhibition zone at 30 ${\mu}$g/disc), Candida albicans ATCC 14053, (2 mm inhibition zone and 2 mm inhibition zone at 30 ${\mu}$g/disc), and the dermatophytic fungi Trichophyton mentagrophytes ATCC 28185, (12 mm inhibition zone at 30 ${\mu}$g/disc) and Cladosporium resinae ATCC 52833 (2 mm inhibition zone at 30 ${\mu}$g/disc). This bibenzyl compound (4) exhibited antimicrobial activity.

While conducting a floristic study of Korean hepatics, we discovered two unrecorded species, which were collected from wind holes near the Donggang River, Korea. Mannia fragrans (Balb.) Frye & L. Clark and Mannia androgyna (L.) A. Evans are hereby reported for the first time in Korea. M. androgyna is characterized by pale grayish oil bodies in both the aerenchyma and basal tissue, and saccate spores with a conspicuous proximal disc. M. fragrans is characterized by a gynoecial segment with a whitish apical brush of scales, a commonly aromatic smell, and areolate spores with a conspicuous proximal disc. Two unrecorded species are described and illustrated based on Korean material.

From the Panax ginseng chloroplast, the psbE and psbF genes, encoding the $\alpha$- and $\beta$-subunits of cytochrome b-559 of the photosystem II reaction center, respectively, were cloned and characterized. The psbE and psbF genes were composed of 252 and 117 nucleotides, respectively. The deduced amino acid sequence of the $\alpha$-subunits showed 95%, 93%, and 91% homology to monocots, dicots, and liverwort, respectively, whereas the $\beta$-subunits showed approximately 98% to 95% homology to the same species. Southern blot analysis revealed that a single copy of the psbEF gene exists in the chloroplast plastid. Northern blot analysis indicated that the psbE and psbF genes are cotranscribed as a polycistron.

Dumortiera hirsuta (Sw.) Nees (Dumortieraceae) is a thallose liverwort distributed in tropics and subtropics. It is the only species in family Dumortieraceae, which is the second basal family in order Marchantiales. D. hirsuta is characterized by hairy receptacles and lacking air chamber. The complete chloroplast genome of D. hirsuta was successfully rescued from raw reads generated by HiSeq4000. Its total length is 122,050 bp consisting of four regions: large single copy (LSC) region (81,697 bp), small single copy (SSC) region (20,061 bp), and two inverted repeats (IRs; 10,146 bp per each). It contained 129 genes (84 coding DNA sequence (CDS), eight rRNAs, and 37 tRNAs); 18 genes including four rRNAs, and five tRNAs are duplicated in the IR regions. The overall GC content of D. hirsuta is 28.7%, which is almost same to that of Marchantia paleacea. Phylogenetic tree based on all genes from whole chloroplast genomes will provides phylogenetic position of D. hirstua. This sequence will be an fundamental resources for further researches of order Marchantiales.

약용 식물의 추출액이 자가영양배양세포의 광합성전자전달계에 미치는 영향을 조사하기 위해 9종의 약용식물 추출액으로부터 종자발아, PA세포의 엽록소 억제정도, DCIP의 환원율, 세포 생존율, 광계 I의 전자전달활성, 단백질에 미치는 영향을 조사한 결과는 다음과 같다. 1. 식물의 추출액을 농도별로 처리하였을 때 10％ 처리시 전 식물체에서 상추의 발아억제 현상을 나타내었고, 특히 백두옹과 초오 추출물 10％ 처리시는 100％ 억제를 나타내었다. 2. 백두옹의 증류수 및 MeOH 추출액을 PA세포에 처리한 경우 엽록소의 생성을 100％ 억제 하 였다. 이는 광합성 전자전달 저해제로 알려진 DCMU 10-3M 처리와 동일한 억제 효과였다. 3. PA세포에 추출물 처리시 백두옹이 힐반응 억제가 가장 컸으며, 세포 생존력은 가장 낮았다. 4. 광합성 산소발생은 반하, 독활, 백두옹, 만형자 추출액 처리시 14-77％ 억제되었고, 특히 PA 세포 2ml 반응액에 백두옹 추출물 60rl 처리시 50％ 산소발생 억제를 나타내었다. 5. 추출액을 PA 세포에 처리한 후 단백질을 추출하여 SDS-PAGE를 이용하여 조사한 결과 대조구에 비하여 백두옹 추출물 10％ 처리에서 14KD, 31KD, 41KD, 53KD, 73KD의 밴드가 나타나지 않았다.
