During an investigation of microfungi from various ecosystems in South Korea, two novel fungal species (KNUF-22-094 and KNUF-23-321C) were discovered within the genera and . The strain KNUF-22-094 stands out among other species due to its distinctive conidiogenous cells and conidial size ranges. The conidiogenous cells of KNUF-22-094 measured 2.

A single Pectobacterium-like strain named 13-115 was isolated from a specimen of diseased cucumber stem tissue collected on Jeju Island, South Korea. The strain presented a rod-like shape and was negative for Gram staining. When grown on R2A medium at 25 °C, strain 13-115 formed round, convex and white colonies.

Article Synopsis
  • * Ethanol extracts of apple blossom (ABE) were tested for toxicity and their effect on melanogenic enzymes using western blot analysis, revealing a dose-dependent decrease in key proteins.
  • * The phenolic compound kaempferol, identified in ABE, was found to mimic this inhibitory effect on melanogenesis, suggesting that apple blossoms could be utilized in cosmetic and food applications for their whitening properties.

Article Synopsis
  • Researchers studied how artificial pigmentation affects red apple quality, focusing on flavonoid diversity and gene expression in immature and color-turning 'Fuji' apples.
  • They found that UV-B light significantly increased anthocyanin accumulation in apple skin, with immature apples being more responsive to this and methyl jasmonate (MeJA) treatment.
  • The study suggests that using UV-B light and MeJA can enhance pigmentation and improve color quality in less-pigmented apples shortly after harvest.

Background: Ultraviolet B (UVB) irradiation is viewed as the main factor of skin aging, associated with acceleration of elastin, collagen degradation and expression of matrix metalloproteinases (MMPs). Apples are one of the most commonly eaten fruits in the world, and isoquercitrin is the main active ingredient in new bred varieties "Green ball" apple. Therefore, we are studying the functionality of the active ingredient of apple, a natural raw material that does not have toxicity or sensitivity problems.

This study aimed to elucidate whether 1-methylcyclopropene (1-MCP) treatment delays the fruit softening mechanism associated with the fruit quality of the newly released apple cultivars "Summer King" and "Green Ball" during cold storage. For both cultivars, the fruit treated with 1-MCP exhibited lower internal ethylene concentration, higher firmness, and higher titratable acidity relative to the control fruit, in association with less fruit softening. In addition, the treated fruit significantly delayed fresh weight loss and reduction of soluble solids content, especially in "Green Ball.

We investigated the effects of sucrose and nano-silver (NAg) on extending the vase life of cut carnation flowers "Edun". Sucrose (pulse treatment) suppressed ethylene production by downregulating the genes that code for its biosynthesis. Relative to the control, however, sucrose significantly promoted xylem blockage on cut stem surfaces and reduced relative fresh weight, antioxidant activity, and cysteine proteinase inhibitor gene () expression.
