Peronospora is the largest genus of the order Peronosporales (Oomycota) and contains more than 550 accepted species, which causes downy mildew on many economically important crops. During a survey of downy mildew flora in Korea, a previously unreported species of Peronospora has been found on Corydalis ambigua. Based on molecular phylogenetic and morphological analyses, the causal agent was identified as Peronospora bulbocapni. This is the first report of Peronospora bulbocapni occurring on Corydalis ambigua in Korea.

Objective : For the purpose of developing Korean herbology of the plants to Fumariaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article.Methods : Books and research papers about Herbology which published at home and abroad were examined.Results : A list was made about Fumariaceae plant which were cultivated or grew naturally in Korea, after investigated the data on domestic and foreign Fumariaceae plants. Out of those lists, serviceable plants were selected and with those available plants, their distributions were analysed and parts which can be used as medicines were divided into 3 categories such as oriental medicine name, scientific name and non-official name. Fumariaceae's properties flavor, channels they use, effects, and toxicity were also noted. Fumariaceae (grew in Korea) were divided into 3 classes with 23 species. Out of those, 2 classes with 9 species were found serviceable which indicates 39% of all. Out of all 23 species of Fumariaceae family, Corydalis genus were found 21 species, which were shown the most. Among Fumariaceae species, Corydalis genus were found 8 medicinal plants, which were shown the most. Out of all serviceable parts in Fumariaceae, Herba and Tuber parts took first place as 5 species. There are 2 toxic species and 3 toxic medicinal parts, the survey said.Conclusion : There were totaled to 3 genera and 23 species in Fumariaceae in Korea and among them medicinal plants are 2 genera, 9 species, some 39 in total.

The development of the female gametophyte of Corydalis albipetala, C. ambigua, C. filistipes, C. nobilis, C. solida, C. ophiocarpa have been comparatively investigated using laser scanning confocal microscope (LSCM) and light microscope. An archesporium was originated from one of the outmost parietal cells beneath the one-layered epidermis of protuberant nucellus, and acted directly as a megaspore mother cell (MMC). These species had linear tetrads after successional meiotic division during the megasprogenesis. A functional megasprore developed from one of the tetrad in the chalazal end, and the rest three being degenerated. The developmental type of the female gametophyte was monosporic in accordance with the Polygonum type. Prior to anthesis the female gametophyte was organized. So mature embryo sac was comprised a three-celled egg apparatus, three large antipodals were developed from the apex of each antipodal cell, and extended toward micropylar end to be contacted with egg apparatus. Two synergids were usually observed as degenerated condition, and in this time the apices of antipodal haustoria were connected with the degenerated synergids. The developmental characteristics of seven-nucleate female gametophytes were common in all the species investigated. But the shape of mature embryo sac was ovoidal in C. albipetala, C. filistipes, C. ophiocarpa and C. solida, reflexed in C. ambigua, and rather flattened ovoidal in C. nobilis. Also, the type of megasporangium was anatropous in all the species except C. ambigua with campylotropous ovule.

In this study, plant samples of five species were collected from the Dokdo islands in South Korea. Plant samples such as Asparagus schoberioides, Corydalis platycarpa, Festuca rubra, Sedum oryzifolium, and Setaria viridis were collected from the Dongdo and Seodo. Endophytic fungal strains were isolated from the roots of five plants from the Dokdo islands. Thirty-three fungal strains were isolated from these native plants. All the endophytic fungi were analyzed by internal transcribed spacer (ITS) sequencing (ITS containing ITS1, 5.8s, and the ITS2 region). Waito-c rice seedlings were treated with fungal culture filtrates to test their plant growth-promoting activity. A bioassay of the D-So-1-1 fungal strain isolated from S. oryzifolium confirmed that it has the highest plant growth-promoting activity. All the endophytic fungi belong to four orders: Eurotiales (86%), Capnodiales (3%), Hypocreales (4%), and Incertae sedis (7%). The endophytic fungi were classified as Ascomycota, which contained Aspergillus (12%), Cladosporium (3%), Eurotium (3%), Fusarium (18%), Microsphaeropsis (6%), and Penicillium (58%) at the genus level.
