Artificial pigmentation of apple fruits has been intensely evaluated to generate less pigmented red apples, which are profitable because the changes in fruit quality. In this study, we analyzed diversity flavonoids and patterns flavonoid metabolic gene expression under light irradiation with or without methyl jasmonate (MeJA) treatment immature (S1) color-turning (S2) staged 'Fuji' apples. Further, assessed regulation at level between anthocyanin flavonol light-responsive skins. UV-B...
During an investigation of microfungi from various ecosystems in South Korea, two novel fungal species (KNUF-22-094T and KNUF-23-321CT) were discovered within the genera Microascus Tolypocladium. The strain KNUF-22-094T stands out among other due to its distinctive conidiogenous cells conidial size ranges. measured 2.3–4.3 × 2.0–3.6 µm, notably smaller than those M. rothbergiorum (7.5–11.5 2.5–4.5 µm), sparsimycelialis (5.0–10.0 3.0–5.0 which is considerably larger both dimensions. For...
Marssonina coronaria associated with apple blotch disease causes severe premature defoliation, and is widely distributed in Korea. Thirteen isolates were collected from orchards located Gyeongbuk Province 2005~2007. All displayed over 99.6% 99.2% sequence similarity to each other internal transcribed spacer regions partial sequences of 28S rDNA, respectively. The phylogenetically closely related Chinese isolates. Selected did not differ their pathogenicity. optimum conditions for fungal...
This study aimed to elucidate whether 1-methylcyclopropene (1-MCP) treatment delays the fruit softening mechanism associated with quality of newly released apple cultivars "Summer King" and "Green Ball" during cold storage. For both cultivars, treated 1-MCP exhibited lower internal ethylene concentration, higher firmness, titratable acidity relative control fruit, in association less softening. In addition, significantly delayed fresh weight loss reduction soluble solids content, especially...
We investigated the effects of sucrose and nano-silver (NAg) on extending vase life cut carnation flowers "Edun". Sucrose (pulse treatment) suppressed ethylene production by downregulating genes that code for its biosynthesis. Relative to control, however, significantly promoted xylem blockage stem surfaces reduced relative fresh weight, antioxidant activity, cysteine proteinase inhibitor gene (DcCPi) expression. Consequently, sucrose-treated had shorter lives than control. In contrast, NAg...
The effects of preharvest and postharvest treatments 1-methylcyclopropene (1-MCP) in combination or alone on fruit quality the incidence physiological disorders during storage ‘Fuji’ apples [ Malus sylvestris (L.) Mill var. domestica (Borkh.) Mansf.] at 20 0.5 °C were investigated. Preharvest 1-MCP (Harvista) applied 4 10 days before harvest (DBH), then either untreated treated with (SmartFresh) postharvest. Fruit stored for up to weeks 36 weeks. At harvest, starch pattern indices watercore...
As solid tumors outgrow the surrounding vasculature, they encounter microenvironments with a limited supply of nutrients. Therefore, in order to survive, tumor cells need adapt glucose-deprived environments. In present study, we examined signaling pathways that lead cancer cell survival response glucose deprivation. We primarily focused on roles adenosine monophosphate-activated protein kinase (AMPK), its upstream LKB1 and c-Jun N-terminal (JNK). Herein, showed DU145 human prostate...
We investigated the effects of 1-methylcyclopropene (1-MCP, SmartFreshTM) concentrations on fruit quality attributes associated with softening and cell wall metabolism in 'Honggeum' apples. Fruits were treated 0, 0.5, or 1 µL·L-1 1-MCP stored at 0 ± 1°C for up to 6 months. In comparison untreated fruits, both similarly reduced internal ethylene concentration delayed reduction firmness titratable acidity; however, weight loss soluble solids content less affected by 0.5 compared 1-MCP. Peel...
The effect of 1-methylcyclopropene (1-MCP) treatment on improving the storability four apple cultivars (‘Hwangok’, ‘Picnic’, ‘Gamhong’, and ‘Fuji’) was investigated by analyzing physiological biochemical factors associated with their postharvest quality attributes. flesh firmness, titratable acidity, soluble solids content were higher in treated fruits than untreated fruits, while opposite results observed for ethylene production. In traits affected 1-MCP varied depending used. Higher...

Photo-aging is caused by cumulative oxidative stress from ultraviolet B irradiation with up-regulating intracellular reactive oxygen species, 4-hydroxynonenal, and matrix metalloproteinases. MMPs are the enzyme that degrades collagens so impair function of dermis. Galangin was identified 1H-NMR 13C-NMR spectroscopy a natural flavonol recently known to have many pharmacological effects such as anti-viral, anti-inflammatory, anti-atopic dermatitis anti-oxidative activities.

The graft cactus (Gymnocalycium mihanovichii) continues to be exported more than 20 countries worldwide. In April 2021, typical bacterial symptoms of soft rot were observed in the (cv. Yeonbit) Goyang, Gyeonggi-do, Korea, resulting economic losses production. stems turned dark brown and flowers covered with black rot. strain designated as KNUB-01-21 was isolated from infected flowers. results morphological biochemical tests isolate similar those Pectobacterium brasiliense.
