The National Forest Seed and Variety Center aims to write a manual for cultivation and characteristic inspection of new seed varieties in Korea, serving dual purposes. The first is the enhancement of the test guidelines, particularly the distinctness, uniformity and stability (DUS) test, for new seed variety, where research and examination are conducted based on the test guidelines. However, if the crop-specific test guidelines are initially reorganized, the details are unclear. Therefore, it seeks to maintain a written record to prevent confusion when the person in charge is changed. The second is to encourage the development of new varieties. By incorporating general characteristics and cultivation techniques in the manual, it seeks to encourage breeders to develop new varieties. Additionally, it serves as an important chronological record of the creation process, thereby helping future manual authors. This article introduces the current status of new plant variety protection and outlines the significance of creating a manual for cultivation and characterization of Actinidia arguta for screening new varieties.

In this study, we investigated in vitro anti-obesity activity of Parthenocissus tricuspidata (Siebold & Zucc.) Planch stem (PTS) in mouse adipocytes 3T3-L1 cells. PTS inhibited lipid accumulation and reduced the expression level of the proteins such as C/EBPα, PPARγ and FABP4 associated with adipogenesis in 3T3-L1 cells. In addition, PTS increased lipolysis-related protein expression such as p-AMPK, ATGL and p-HSL, and reduced perilipin-1 in 3T3-L1 cells. Taken together, PTS may have anti-obesity activity through inhibiting adipogenesis and inducing lipid lipolysis in adipocytes. Based on these results, PTS is expected to be used as a potential functional agent for anti-obesity.

In this study, we measured the inhibitory activity of Pinus densiflora leaf (PDL) against excessive lipid accumulation in mouse preadipocyte, 3T3-L1 cells to investigate whether PDL exerts anti-obesity activity. Lipid accumulation and the protein level were measured using Oil red O staining assay and Western blot analysis, respectively. We observed that PDL inhibited excessive lipid accumulation and decreased the expression of CEBPα, PPARγ and perilipin-1 related to lipid accumulation in 3T3-L1 cells. Therefore, considering these results, PDL can be used as a potential agent for anti-obesity.
