        The World Vegetable Center (WorldVeg) maintains the world’s largest public vegetable germplasm collection. The Genebank contains over 65,000 accessions and consists of more than 130 genera and 330 species. It includes around 12,000 accessions of indigenous vegetables. The WorldVeg Korea Office (WKO) has been conducting regional adaptability evaluations in the fields of the National Institute of Horticultural and Herbal Science (NIHHS), with a focus on major solanaceous vegetable crops such as tomato, chili, and bell pepper. As climate change significantly affects vegetable crop productivity, the development of high-performing cultivars, tolerant to various abiotic and biotic stresses with enriched nutrients inside, is essential to enhance agricultural sustainability and human health. In this regard, the evaluation of growth and horticultural characteristics of pepper and tomato accessions from the WorldVeg will help contribute to the generation of new and improved cultivars, to address global challenges that affect food security, sustainability, and adaptation to climate change. Here, we summarize our activities and the results of the regional adaptability evaluation using the WorldVeg accessions of pepper and tomato germplasms.

        Protected agriculture has great potential for the vegetable industry in the Philippines as it allows the application of modern cultivation techniques to mitigate adverse weather conditions and enable farmers to manage pests and diseases efficiently. Thus, to address the increasing demand for food in the Philippines, one strategy to increase vegetable production which is tested and/or proven is through the intensified use of protective structures. This review describes the magnitude and potential of agriculture in the Philippines, focusing on the protected cultivation of horticultural crops. The Philippines is far behind in greenhouse technologies compared to other Asian countries where thousands to millions of hectares are used for protected vegetable cultivation. Several studies have investigated the economic viability and applicability of low- and high-cost protective structures in typhoon-prone countries such as the Philippines, demonstrating that protective structures are feasible and profitable. Also, the impact of protected cultivation as compared to the open field has resulted in significantly higher yield and better quality of produce. Hence, the Philippine government with the assistance of the Republic of Korea agreed to improve the country’s flagging vegetable industry and endeavor to attain the status of a food-secure country through the establishment of smart greenhouse technologies. Overall, despite the limitations due to the high cost of electricity and construction protected cultivation facilities including required technologies provide greater advantages for seasonal and off-seasonal vegetable crop production compared to that in the open field. Moreover, such technology can be applied to various geographical locations such as plains, hills, deserts, rural, and urban areas.

        The purpose of this study was to investigate the effects of extract mixture of C. wilfordii and P. umbrosa (IPLUS-CWPU) on bone growth in 4-week old young male SD rats. To confirm the effect of IPLUS-CWPU, we measured the length of bone growth plate, the ratio of proliferative zone to the length of growth plate and the expression level of insulin-like growth factor, IGF-1. The IPLUS-CWPU treatment shows a significant increase of tibial and femoral growth plate and the ratio of proliferative zone in growth plate. Especially, the length increased by 13.9% and 25.3% in the tibia and femur, respectively, in the high-dose group compared to the normal group. Moreover, the expression of IGF-1 gene in liver was upregulated in IPLUS-CWPU treated groups. These results indicated that IPLUS-CWPU administration could increase the proliferative zone of bone growth plate in early developmental stage by upregulation of IGF-1 gene.

        This study was performed to investigate the effects of Acer tegmentosum Maxim. extract (ATE) on non-alcoholic fatty liver in Sprague Dawley (SD) rats. During oral administration of ATE, non-alcoholic fatty liver was induced by treatment with DL-ethionine. The lipid, total cholesterol (T-CHO) and malondialdehyde (MDA) in the liver tissue of ATE-fed rats showed lower levels, as compared to ATE-unfed rats. In ATE-fed rats, the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and γ-glutamyl transferase (GGT) were lower than the case of ATE-unfed rats. Oil red staining of the liver showed that the lipid deposits were decreased by feeding ATE. These results strongly indicated that ATE has positive effects of protection against non-alcoholic fatty liver formation.

        This study was conducted in order to investigate the effects of Acer tegmentosum Maxim. extract (ATE) in prevention of liver injury. After oral administration of ATE to SD rats, liver injuries were induced by treatment with CCl4, galactosamine, or ethionine. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride, and cholesterols in blood were used as indicators of liver damage. When acute hepatitis was induced by CCl4 or galactosamine, ATE-fed rats showed a lower level of AST and ALT in plasma than ATE-unfed rats. In the case of ethionine-induced fatty liver, triglyceride levels in plasma were reduced in ATE-fed rats, compared with ATE-unfed rats. These results indicate that Acer tegmentosum Maxim. extract protected against hepatic failure.
