세계화에 따른 국제교류가 증가함에 따라 외래식물의 국내 유입 또한 증가하고 있다. 외래식물이 자연생태계에 미칠 수 있는 여러 부정적인 영향들이 알려지면서 전 세계적으로 자생식물의 보전을 위한 국가 차원의 관리 및 여러 정책들이 수행되고 있지만, 국내의 경우 이들의 현황 파악조차 미흡한 실정이다. 본 연구는 국립수목원에서 수행하는 '외래식물 다양성 변화 및 위험성 평가' 과제의 일환으로 수행된 연구결과 중 일부로, 국내에 유입되어 정착화되었거나, 재배지로부터 일출되어 자연생태계로 확산 가능성이 높은 외래식물의 현황을 파악하였고, 산림청 국립수목원을 비롯한 타부처 외래식물 목록과 관련 주요 도감 및 문헌들을 재검토하였다. 또한 이들을 원산지, 도입시기 및 정착 여부에 따라 체계화하였고, 침입외래식물로 분류되는 외래식물들은 국내 분포정보를 바탕으로 확산정도를 등급화 하였다. 그 결과 국내에 분포하는 외래식물은 96과 353속, 595종, 6아종, 11변종, 1품종, 6잡종의 총 619분류군으로 파악되었으며, 이 중 사전귀화식물 30분류군, 잠재침입식물 214분류군이었고, 침입외래식물은 총 375분류군으로 5등급(widespread, WS)이 19분류군, 4등급(serious spread, SS) 16분류군, 3등급(concerned spread, CS) 19분류군, 2등급(minor spread, MS) 37분류군, 1등급(potential spread, PS) 284분류군으로 나타났다. 외래식물은 앞으로도 계속 유입될 것이고, 이들의 분포 또한 환경 및 기타요인에 의해 변하기 때문에 지속적인 현황파악이 수행되어야 한다.

Ecological and ethnomedicinal survey of plants was conducted in one hundred and twenty homesteads in Mbala, Amuda, Umuaku, and Nneato communities of Nneochi Local Governement Area, Abia State-Nigeria. A total of ninety-one medicinal plant species belonging to seventy-eight genera and forty-eight families, used in the treatment of malaria, yellow fever, fibroid, hepatitis, convulsion, hypertension, diabetes, insomnia, ulcer, rashes, low sperm count, snake bite, among others, were documented. Plant remedies were prepared mostly as infusions or decoctions from different plant parts with mainly water, and palm wine/gin sometimes. The highest number of medicinal plant species (73) was recorded in Mbala, followed by Amuda (71), Umuaku (68) and Nneato (61). Medicinal plant species diversity was highest in Amuda (Simpson 1-D=0.9621;H=3.663), followed by Umuaku (Simpson 1-D=0.9481; H=3.471), Mbala (Simpson 1-D=0.9345; H=3.341), and Nneato (Simpson 1-D=0.9307; H=3.277), respectively. Similarity in medicinal plant species was highest between Umuaku and Nneato (76.71%), followed by Amuda and Umuaku (75.95%), Mbala and Amuda (71.43%), while Mbala and Nneato had the lowest similarity (59.52%). The results of the study showed that traditional medicine is pivotal in the treatment of ailments in the study area, and that the indigenous people of Nneochi have recognized the need to conserve medicinal plants of importance ex situ within homesteads due to threats from unsustainable exploitation and deforestation.

Resource plants are important and have strong potential for a variety of utilities as crops or pharmaceutical materials. However, most resource plants remain wild and thus their utility for breeding and biotechnology is limited. Molecular markers are useful to initiate genetic study and molecular breeding for these understudied resource plants. We collected various wild collections of Peucedanum japonicum which is indigenous resource plants utilized as oriental medicine and leafy vegetables in Korea. In this study, we produced two independent whole genome sequences (WGSs) from two collections and identified large scale polymorphic simple sequence repeat (pSSR) based on our pipeline to develop SSR markers based on comparison of two WGSs. We identified a total of 452 candidate pSSR contigs. To confirm the accuracy and utility of pSSR, we designed ten SSR primer pairs and successfully applied those to seven collections of P. japonicum. The WGS and pSSR candidates identified in this study will be useful resource for genetic research and breeding purpose for the valuable resource plant, P. japonicum.

The Kashmir Himalaya, known for its indigenous and endemic flora, also provides home to a large number of exotic plants, which exhibit a wide taxonomical and distributional stretch. Although, some preliminary studies have been carried out in the region on some aspects of its exotic flora, the inventorization and documentation of its exotic have received a little or negligible attention. There is a lot of scope of these exotic plant species in Kashmir valley, but lack of authentic identification has been as a big hurdle in their scientific management. It is in this backdrop that the present floristic study was carried out to identify, inventorize, document and characterize the exotic plant species grown in the Valley. The present study has revealed that Kashmir Valley grows 317 exotic plant species, which belong to 209 genera in 85 families. Dicotyledons are the largest group, represented by 252 species in 163 genera and 67 families. Monocotyledons comprise 52 species in 37 genera and 13 families. Gymnosperms are the smallest group, with 13 species distributed in 9 genera and 5 families. Asteraceae is the largest family containing 33 exotic species.

Ceratocystis wilt disease has caused significant mortality in duku (Lansium domesticum) since 2014 and has now spread to all districts in South Sumatra, Indonesia. Recently, 16 isolates from duku representing populations from various districts in South Sumatra were isolated. Analysis for the morphological characteristic of the isolate showed that the population has a uniform morphology. Genetic analysis based on internal transcribed spacer (ITS) and β-tubulin sequences verified that the population has being dominated by the ITS5 haplotype of Ceratocystis fimbriata and a new ITS group, the ITS7b haplotype that was localized in Musi Banyuasin. Both haplotypes were highly pathogenic to duku. Inoculation tests on various forest and agroforestry plant hosts showed that both haplotypes were highly pathogenic to Acacia mangium, moderately pathogenic to Acacia carsicarpa, Eucalyptus urophylla, and Melaleuca cajuputi, but weakly pathogenic to Dyera costulata, Hevea brasiliensis, and Alstonia scholaris. Therefore, this pathogen becomes a serious threat to Indonesia's biodiversity due to its ability to infect forest and agroforestry plants, especially the indigenous ones.

The paper provides a brief account of 11 plant species used by the tribal people of the district Purulia, West Bengal, India. Most of the plant species are common in this district and some have not been reported earlier for abortive purposes, pharmacology for preparation of medicines for antifertility. All these data were obtained from the tribal medicine men (ojha). At least 10 interview reports of various tribal medicine men were recorded. Parts of various medicinal plants were observed personally, collected and preserved as herbarium specimens for proper identification. The reports of various indigenous methods may help to give some clue in searching the potent contraceptives.

Asthma is a chronic inflammatory disease of the lungs, characterized by increased sensitivity to bronchoconstriction associated with infiltration of immune cells and mucus hyper secretion. In South Africa, the indigenous plant Siphonochilus aethiopicus, is used by traditional health practitioners to treat colds and flu, wheezing of the chest, coughs, influenza, sinus problems and mild asthma. In this study we aimed to investigate the potential anti-inflammatory and immune-modulating properties of S. aethiopicus in vitro. The dried and powdered S. aethiopicus plant material was extracted with organic solvents. The dried extracts were screened in vitro in the transcription response, NF-${\kappa}B$ and a cytokine assay. Significant activity was observed for organic extracts of the plant in these assays. This study provides evidence that S. aethiopicus has anti-inflammatory and immune-suppressing properties in vitro. These findings may support anecdotal accounts of its effectiveness against allergic asthma.

Acanthopanax species are well known medicinal plants in Korea for their adaptogenic efficacy. Regarding to the botanical classification of Acanthopanax koreanum, an indigenous species in Jeju island of Korea, it has been classified as different species of Acanthopanax genus. However, the morphological characteristics of A. koreanum are very similar with other Acanthopanax species, especially with A. gracilistylus. In order to provide further classification information among these botanically related species, microscopic and morphological studies on these Acanthopanax species were performed. In this result, it has been found that A. koreanum is similar to A. gracilistylus in terms of anatomical observation and was distinguished from A. sieboldianus by their morphological and anatomical differences.
