The root of Hibiscus syriacus (Malvaceae) has been used for treatment fungal diseases such as tinea pedis (athlete's foot). In this study, we investigated the antifungal constituent Ggoma, which was produced by a mutation breeding using gamma ray irradiation, and compared activity H. Ggoma its parent type. According to results, methanolic extract exhibited four times higher than type against Trichophyton mentagrophytes. Following purification through various column chromatographies,...
Soybean (Glycine max L.) is one of the most important crop plants in Republic Korea. Here, we conducted a soybean virome study. We harvested total 172 leaf samples showing disease symptoms from major soybean-growing regions Individual were examined for virus infection by RT-PCR. Moreover, generated eight libraries representing provinces pooling and four single samples. RNA-seq followed bioinformatics analyses revealed 10 different RNA viruses infecting soybean. The proportion viral reads...
The tobacco cutworm, Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae), is one of the most serious pests in field crops, vegetables, and ornamentals. Temperatures (15, 20, 25, 27, 30, 35, 40 °C), host plants (soybean (Glycine max (L.)), maize (Zea mays L.), groundnut (Arachis hypogaea L.) azuki bean (Vigna angularis (Willd.) Ohwi & H. Ohashi,), artificial diet-dependent developmental parameters survival S. were examined this study. Stage-specific such as threshold development...
Xylaria, belonging to the Ascomycotina, is known produce diverse classes of bioactive substances. In an effort identify chemical constituents fruiting bodies Xylaria polymorpha, linoleic acid (1), methyl ester (2), ergosterol (3), 4-acetyl-3,4-dihydro-6,8-dihydroxy-3-methoxy-5-methyl-1H-2-benzopyran-1-one (4), and 4-hydroxyscytalone (5) were isolated from its methanolic extract. Their structures assigned on basis various spectroscopic studies.
Abstract The perilla seed bugs, Nysius plebeius Distant and hidakai Nakatani, are emerging pests of crop in Korea. Here, we investigated the life‐history variables N. on five commonly grown seeds: [ Perilla frutescens (L.) Britt.], sesame ( Sesamum indicum L.), sorghum Sorghum bicolor (L.)], proso millet Panicum miliaceum L.) foxtail Setaria italic L.). Bug oviposition, total developmental period, adult emergence, longevity weight both species were determined choice no‐choice tests....

BACKGROUND: Deterioration of health-related quality life (HRQOL) and cognitive function is a major concern in patients who underwent glioma surgery. While HRQOL influenced by both tumor non-tumor factors, the influence molecular genetic features on not fully understood. Here we investigated relations among HRQOL, function, genotypes during high grade METHODS: Consecutive surgery were evaluated with scores (EORTC QLQ-C30 BN20 brain cancer modules) tests (digit span tests, verbal fluency,...
Abstract Maruca vitrata is considered as one of the major impediments in boosting up production tropical legumes. Since chemical pesticides have an adverse effect on human health and environment, there urgent need for developing a non‐chemical based method to replace insecticides controlling pests. We investigated oviposition, development adult performances M. at five radiofrequency levels 0 (control without frequency), 5, 10, 20, 30 kHz artificial diet. In addition, effects were also...
이 연구는 남부지역 논에서 동계 사료맥류, 하계 조생종 벼, 추계 하파귀리 등 삼모작 재배기술을 확립하기 위해실시하였다. 월동 사료작물을 벼인 조평벼의 이앙시기에 맞춰 4월 30일 1차 수확한 처리구와 사료맥류의 수확기인 5월 30일에 처리구 모두 곡우호밀이 각각 생초수량 32.0톤/ha과 42.3톤/ha, 건물수량이 5.8톤/ha과 16.5톤/ha로 다른 작물에 비해 높은 수량을 보였다. 조평벼는 6일에 이앙한 처리구보다 6월 4일에 2차 처리구에서 등숙비율이 떨어지고 수량도 약 22% 감소하여 조기 이앙이 유리한 것으로 나타났다. 틈새작물로 재배한 하이스피드 귀리는 8월 28일에 파종한 10월 10일에 출수하였지만 9월 2일에 입모중으로 출수도 하지 못하였으며 파종에 건물수량과 TDN 수량 50%를 못 미치는 결과를 나타내어 파종이 빠를수록 것을 알 수 있었다. 따라서 남부지역에서 삼모작을 하기 위해서는 호밀을 재배하여 전에 후 이앙과 귀리의 적기 쌀 수량과 조사료 확보에...
Perilla (Perilla frutescens L.) is the second most important upland crop and third largest edible oil in Korea (Shin Kim 1994). During a disease survey Busan, September 2021, symptoms of vein necrosis were observed perilla plants, with incidences approximately 30% 50% two fields. Symptoms spots on appeared as leaf dryness water-soaked blotches largely concentrated mid-veins leaves. The lesions initiated or stem gradually turned black brown. Necrosis was also stems. A bacterium isolated...
In July 2023, cases of highly pathogenic avian influenza (HPAI) were reported at 2 shelters for stray cats in Seoul, South Korea. The cause infection was suspected to be improperly sterilized raw food made from domestic duck meat, which manufactured All viruses isolated the and belonged HPAI A(H5N1) clade 2.3.4.4b. gene constellation all most similar that Korea November 2022. Of note, infected harbored mutations E627K or D701N polymerase basic 2, are indicative adaptation mammals. Postmortem...
Abstract Anthropogenic-mediated climate change is expected to negatively affect pest management in agriculture. Hence, we investigated the oviposition, immature mortality, and developmental processes of Spodoptera species ( exigua (Hübner) litura (Fabricius)) under different temperatures (20, 25, 30°C) relative humidity (RH) (30–35, 50–55, 70–75, 90–95%) conditions. For fecundity, mouths each were released into a rectangular box whose inner walls covered with sheet white paper for...
