- The aim of this study was to explore the effects of vinegar extract from seed of common buckwheat (Fagopyrum esculentum Moench) and seed of tartary buckwheat (F. tataricum Gaertner) on acute ethanol-induced hangover in Sprague-Dawley rats. Vinegar extract from buckwheat is rich choline, quercetin and its glycoside, rutin known as flavonoid antioxidants. The test extract containing buckwheat was proven to alleviate hangovers through a significant reduction in the concentration of alcohol and acetaldehyde in the context of an alcohol-induced hangover model. Hepatic alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities were significantly higher in buckwheat vinegar-treated rats than in ethanol-treated rats. Moreover, tartary buckwheat vinegar upregulated antioxidant enzyme such as superoxide dismutase and Catalase activities in liver tissues. These results suggest that buckwheat vinegar extract could alleviate ethanol-induced hangover symptoms by elevating activities related to hepatic ethanol-metabolizing enzymes against ethanol induced metabolites, and in particular, tartary buckwheat should be further developed to be a novel anti-hangover material. - COLLAPSE

- This study aimed to assess the potential use of Paeonia lactiflora Pall. seed cake (PSC). The extraction yield of the PSC extract ranged from 22% to 45%, depending on the extraction solvent used. The PSC extract showed significantly higher levels of total polyphenols and flavonoids contents, and radical scavenging compared to the P. lactiflora seed oil (PSO) extract. The antibacterial activity of the PSC extract was superior to that of the positive control and remained effective for up to 48 hours. Furthermore, when the PSC extract was applied, it significantly reduced the inflammatory response induced by LPS, demonstrating the anti-inflammatory activity of PSC. This study confirmed the effective bioactivity not only in PSO, but also in the PSC extract, highlighting the potential of PSC as a bio-health ingredient. - COLLAPSE

- We aimed to assess the potential growth-promoting effects of buckwheat sprout on intestinal bacteria and their anti-inflammation effects in a cellular model of intestinal inflammation. The growth of Bifidobacterium longum ssp. infantis BT1 was enhanced with the addition of the sprout extract of tartary buckwheat. Further, in the inflammatory model cells cultured with Raw 264.7 cells were treated with buckwheat sprout including each 10 probiotics before the addition of lipopolysaccharide (LPS) to induce inflammation in Raw 264.7 cells. Buckwheat sprout in both Bifidobacterium longum ssp. infantis BT1 and Lacticaseibacillus paracasei LPC5 significantly reduced the production of NO and PGE2. The above results indicate that buckwheat sprout extract which contains with various physiologically active substances such as rutin, quercetin, and choline is effective in suppressing NO and PGE2 production, which are inflammation-related indicators. The present study suggests that buckwheat sprout could induce positive effects on the intestinal beneficial bacteria and in anti-inflammation. - COLLAPSE

- This study was conducted to investigate the growth and fruit characteristics of recently introduced or bred varieties in Korea and to review domestic adaptability. As for the sprouting rate among cultivars, ‘Stella’ was the highest at 91.6%, followed by ‘My Heart’ (78.3%), ‘IFG-6’ (77.3%), and ‘Hongju Seedless’ (73.2%). As for the flower incidence rate by cultivar, 'Stella' was the highest at 113.5%, and ‘IFG-6’ had a lower flower incidence at 45.3% compared to other cultivars. The diameter of shoots was less than 11.0 ㎜ in the other three cultivars except for ‘Hongju Seedless’, and ‘Hongju Seedless’ was the thickest at 12.5 ㎜ and ‘Stella’ was the thinnest at 9.6 ㎜. The berry weight of 'My Heart' was 11.3 g, heavier than other cultivars, followed by ‘Stella’, ‘IFG-6’ and ‘Hongju Seedless’. Soluble sugar content at harvest time by cultivar was about 19.0˚Bx or higher, with ‘IFG-6’ having the highest level of 20.2˚Bx, followed by ‘My Heart’, ‘Stella’, and ‘Hongju Seedless’. Acidity was the lowest in ‘My Heart’ at 0.39%, followed by ‘IFG-6’, ‘Stella’ and ‘Hongju Seedless’. As for the coloring, in the case of ‘My Heart’, the skin color did not change to red even after the harvest season, therefore the grapes were irregularly colored, so it was judged that the development of cultivation technology to enhance the coloring was necessary. - COLLAPSE

- The in vitro organogenesis is one of important issues in plant embryology, and somaclonal variations are existing in calli and/or regenerants induced from a process of the organogenesis with in vitro circumstances. In this study, expressions of organogenesis-related genes were evaluated and genetic stability of regenerants derived from the process of in vitro organogenesis were measured using ISSR markers in Imperata cylindrica ‘Rubra’, Poaceae. The expressions of organogenesis-related genes were detected all of regenerants at the process of the organogenesis. All ISSR markers produced with an average of 71 bands per in vitro-cultured regenerants, and the scorable bands were varied from two to eight with an average of 5.14 bands per a primer. The polymorphism rates of the in vitro regenerants were higher than that of mother plants (1.4%), showing 4.1% (pot-cultured regenerants), 4.3% (field-cultured regenerants), 4.2% (in vitro-cultured regenerants), 5.6% (calli with green shoots) and 1.4% (calli), respectively. The genetic similarity matrix (GSM) among all accessions ranged from 0.747 to 1.0 with a mean of 0.868. GSM of the regenerants showed differences (from 0.972 to 1.00) compared with that of mother plants (0.991). According to the clustering analysis, two independent groups were divided into; the one is mother plants and regenerants cultured at room and open field, the other is regenerants cultured in vitro. The results give a new insight for understanding the dynamics of organogenesis in monocot plant. - COLLAPSE

- The harvest time of the late-ripening ‘Fuji’ apple (Malus × domestica) is variable, depending on the coloration of the fruit skin. Ethephon, a plant growth regulator, promotes the ethylene production and induces physiological responses associated with fruit maturation in climacteric fruit crops, such as apples. This study aimed to investigate the effect of ethephon treatment on fruit characteristics after fruit enlargement, with the objective of proposing an economical and stable harvest control method for ‘Fuji’/M.26 apples. Fruit characteristics were assessed at 10-days intervals following the application of 100 ㎎/L ethephon and mixture of 100 ㎎/L ethephon and 0.5% CaCl2 at 145 days after full bloom (DAFB). Starch contents of ethephon-treated (ET) and ethephon with CaCl2-treated (EC) apples began to decrease from 155 DAFB, and the starch contents of ET and EC at 10 days before harvest were similar to those of control at harvest time. Red coloration of fruit skin in EC was lower compared to ET but higher than control. The average fruit firmness was low in ET, while the control and EC exhibited similar levels of firmness. Fruit sugar acid ratios did not show significant differences between treatments. However, the titratable acidity of EC was significantly lower than that of the control at 10 days before harvest. Moreover, fruit sugar acid ratio of ET and EC at 10 days before harvest in 2021 was similar to their sugar acid ratio at harvest time. Therefore, it was thought that fruit maturation and skin coloration could be accelerated by 10 days from the harvest time through the combined treatment of 100 ㎎/L ethephon and 0.5% CaCl2 at the end of fruit enlargement in ‘Fuji’/M.26. - COLLAPSE

- Pepper (Capsicum annuum L.) is an important vegetable and spice crop that has been cultivated worldwide. Pepper fruits have unique taste and aroma, providing a variety of antioxidants and compounds important for human health, which makes a high economic value. In addition, there is a high demand for new pepper varieties, according to consumer’s preference. However, pepper is a recalcitrant plant for in vitro tissue and organ differentiation and plant regeneration, which makes it difficult to develop demanded varieties using newly developed technologies such as genetic engineering and gene editing. In this study, tissue culture and regeneration conditions were investigated using seven pepper varieties that were obtained from the core-collection of Seoul National University. We observed callus and bud induction and shoot formation using several media composition composed of different cytokinins and auxin concentrations. As a result, it was found that there were differences in callus induction and shoot formation of each variety depending on the hormone composition, and the highest regeneration was shown when the medium containing Zeatin Riboside and the petioles of seedlings were used. In particular, out of seven pepper varieties, CMV980 exhibited a higher regeneration efficiency (approximately 48%) than other varieties, followed by Yuwolcho. Therefore, this study provides CMV980 and Yuwolcho as good candidates that can be used for pepper transformation, which might contribute to the development of various varieties through gene editing technology in the future. - COLLAPSE
