In 2010, disease symptoms, including necrotic lesions on stems and leaves with circular yellow-brown or irregular brown color patches, were observed on cool-season turfgrass at golf courses (OHCC) and the Daegu University research farm in Gyeongbuk, Korea. We isolated the causal agent and identified it as Waitea circinata var. zeae by morphological characterization and molecular analysis. To the best of our knowledge, this is the first report of brown patch caused by W. circinata var. zeae on cool-season turfgrass in Korea.

항생물질첨식잠은 체중이 현저하게 무거웠고 체색도 담황색으로 변하며 영견습성도 차이점이 나타났으므로 유전형질의 변화를 생각할 수 있으며 앞으로 우량잠품종 육성에도 기대되는 바가 있는 것으로 본다.

'Honghwa' an Asiatic hybrid lily was released in 2001 at National Horticultural Research Institute (NHRI), Rural Development Administration (RDA), and Suwon, Korea. The cross was made in 1994 between Lilium Asiatic 'Avignon', a scarlet red colored, and L. Asiatic 'Connecticut King', bright yellow colored. It was preliminarily selected as 'A96-3' in 1996. Multiplication and bulbing, and characteristic tests were performed from 1997 to 2000. The evaluation of characteristics was made investigated as 'Wongyo C1-31' in 2001 at Suwon. 'Honghwa' flowers at the beginning of June and grows to 111.4 cm stem length. Flowers are upward-facing, unspotted with orange petals. Year-round flowering is possible by storing the bulb at $-1.5^{\circ}C$ conditions. It is necessary to add calcium to the fertilizer or remove side scales to prevent leaf scorch. It is needed to control Botrytis disease during wet season.

Hepatic fibrosis is a common chronic liver diseases, characterized by the excessive deposition of extracellular matrix (ECM). Activation of hepatic stellate cells (HSC) is proliferative and fibrogenic and accumulating ECM. Transforming growth factor $(TGF)-{\beta}1$ is a critical mediator of HSC activation and ECM accumulation leading to fibrosis. Tenebrio molitor (TM), known as yellow mealworms, is reported in many countries as the nutritional value of foods. Our study has aims of finding liver function improvement effect of S. cerevisiae fermented Tenebrio molitor (SCTM) in vitro model. SCTM regulates $TGF-{\beta}1$ induced hepatic fibrosis via regulation of the $TGF-{\beta}1/Smad$ signaling. Also, we compared the components increased by yeast fermentation. It is possible to make a useful insect-derived alternative food in the improvement of hepatic liver disease.

Sclerotinia rot symptoms were observed in stringy stonecrop (Sedum sarmentosum) plants growing in vinyl greenhouses in Yeoju and Icheon, Gyeonggi Province, Korea, during disease surveys in spring 2019 and 2020. The initial symptoms were soft rot on stems and leaves at or above the soil line. Furthermore, the symptoms progressed upwards, and the infected plant parts exhibited white to grayish-yellow discoloration. The infestation of diseased plants in the vinyl greenhouses was 1-5% at the two locations examined. Eight isolates of Sclerotinia sp. were obtained from lesions of the diseased plants. The isolates were identified as Sclerotinia sclerotiorum based on their morphological and molecular characteristics. In addition, artificial inoculation tested three isolates of S. sclerotiorum for pathogenicity on stringy stonecrop plants. All the tested isolates caused Sclerotinia rot symptoms in the inoculated plants. The symptoms were similar to those observed in plants from the vinyl greenhouses investigated. This study is the first report of S. sclerotiorum causing Sclerotinia rot in stringy stonecrop.

Rice contains a wealth of genetic diversity, both within Oryza sativa and in related A-genome species. Decades of genetic research into this diversity have identified dozens of major genes contributing to a wide variety of important traits, including disease resistance, abiotic stress tolerance (drought, salinity, submergence, heat, cold etc.), grain quality, flowering date and maturity and plant architecture. Yet despite these opportunities, very few of the major genes and QTLs known have been successfully applied through rice breeding programs to produce sustained changes in farmer's fields. This presentation will briefly examine some of the factors limiting application of major genes in the mainstream breeding programs, and steps that have been taken to alleviate those limitations. As a result of these interventions, dozens of major genes that were previously unavailable to breeders are now being used confidently in the variety development process. Case studies will be discussed of genes critical for blast resistance worldwide, rice yellow mottle virus for Africa, and new validated QTLs for salinity tolerance.

A fungus strain Stereostratum corticioides PKVL1, belonging to the family Pucciniaceae that causes rust in plants, was discovered on the sheath of the bamboo Pseudosasa japonica leading to the death of the infected bamboo in the following year. Microscopic observation of the yellow fungal mass revealed teliospores with an oval, one-septate (two-celled) structure. The average length and width of teliospores were 31.83±3.57 ㎛ and 20.74±1.72 ㎛, respectively. The large-subunit ribosomal RNA gene was amplified using the LR0R and LR7 primers, showing that the strain PKVL1 had a similarity of 99.34% to previously reported S. corticioides. In particular, the two Stereostratum strains form a separate cluster among the fungi in the family Pucciniaceae. This is the first report in the Republic of Korea of fungal rust occurring on the culm of bamboo rather than on the leaves.

Tan spot (TS), caused by the fungus Pyrenophora tritici-repentis (Died) Drechs, is an important foliar disease of wheat and has become a threat to world wheat production since the 1970s. In this study a globally diverse pre-1940s collection of 247 wheat genotypes was evaluated against Ptr ToxA, P. tritici-repentis race 1, and stem rust to determine if; (i) acquisition of Ptr ToxA by the P. tritici-repentis from Stagonospora nodorum led to increased pathogen virulence or (ii) incorporation of TS susceptibility during development stem rust resistant cultivars led to an increase in TS epidemics globally. Most genotypes were susceptible to stem rust; however, a range of reactions to TS and Ptr ToxA were observed. Four combinations of diseasetoxin reactions were observed among the genotypes; TS susceptible-Ptr ToxA sensitive, TS susceptible-Ptr ToxA insensitive, TS resistant-Ptr ToxA insensitive, and TS resistant-Ptr ToxA toxin sensitive. A weak correlation (r = 0.14 for bread wheat and -0.082 for durum) was observed between stem rust susceptibility and TS resistance. Even though there were no reported epidemics in the pre-1940s, TS sensitive genotypes were widely grown in that period, suggesting that Ptr ToxA may not be an important factor responsible for enhanced prevalence of TS.

Everyone has own color preference and the color preference can affect human psychology in various good or bad ways. Especially patients with chronic diseases often have depressed mood to take pills for their disease treatment. Therefore we evaluate the possibility of their color preference to pharmacotherapy in good way which increases the compliance of pharmacotherapy. We performed this study by a Questionnaire survey for total 150 agreed patients at K University hospital from Aug 7 to Sep 30, 2014. Questionnaire survey was performed to choose color of providing color kit (11 different color range kit) depend on each 16 questions which asked the patient characteristics, health condition, general color preference, color preference for medicine and expectation for drug compliance. In results, most preferred color was blue (20%), whereas disliked color was black (30%) in general life. However, most preferred color for pill was white (32%), for syrup was also white (31%) or orange (28%), and for vitamin was yellow (47%). When we asked the possibility of increasing compliance, if the current taking pill color will be changed for your preference color like a candy bar, 50.4% of respondents marked 4 or 5 of like-scale expressing positive opinion on it. In conclusion, compliance is very important to succeed the treating disease and may apply the psychologic application such as each patient color preference for drug compliance in the future.
