Summary: MYB and BBX transcription factors regulate flavonoid biosynthesis in woodland strawberry. Overexpression of FaMYB5 in woodland strawberry increases anthocyanin and proanthocyanidin content in roots, stems, and leaves. Interaction between FaBBX24 and the N-terminal of FaMYB5 is confirmed. Co-expression of FaBBX24 and FaMYB5 in cultivated strawberry promotes the expression of key genes involved in flavonoid biosynthesis and increases flavonoid content in fruits.

Summary: Leaf removal, shoot thinning, or their combination can affect berry composition, wine quality, and antioxidant properties. Shoot thinning mainly influences wine characteristics, while shoot thinning and leaf removal combination impact proanthocyanidin polymerization and monomeric flavan-3-ols content.

Summary: This study identified and characterized the ripening inducing factor FaRIF in strawberry, which plays a crucial role in controlling key ripening-related processes such as fruit softening, pigment and sugar accumulation. Functional analyses through stable transgenic lines showed that FaRIF is a key regulator of strawberry fruit ripening from early developmental stages, controlling various metabolic pathways and the balance of aerobic/anaerobic metabolism. This research suggests that FaRIF is a potential target for genetic modifications to enhance the quality of strawberry fruits.

Summary: Light quality plays a crucial role in plant growth and development, affecting various aspects of plants. Previous studies have shown that different light qualities can regulate anthocyanin synthesis in plants, but the mechanism of how light quality influences the synthesis and accumulation of anthocyanins in leaves is not fully understood. In this study, the effects of different light qualities on the production of anthocyanins and other metabolites in Loropetalum chinense var. rubrum Xiangnong Fendai plants were investigated. It was found that blue light promoted the reddening of the leaves and increased the content of chlorophyll, carotenoid, anthocyanin, flavonoid, soluble sugar, and soluble protein. On the other hand, ultraviolet-A light caused oxidative stress in the leaves and affected the activities of antioxidant enzymes. The upregulation of several genes related to anthocyanin synthesis and antioxidant defense was also observed under different light qualities. Overall, blue light was more effective in inducing leaf-color changes and enhancing the ornamental and economic value of L. chinense var. rubrum.

Summary: The study compared the responses of fruit quality, anthocyanin content, and gene expression in 'Seolhyang' and 'Jukhyang' strawberry cultivars at different maturity stages and during postharvest shelf life. Fruit dimensions increased then decreased during shelf life, with 'Jukhyang' showing higher soluble solids content and titratable acidity. Different phenotypic responses were observed between the two cultivars in terms of fruit color, phenolic compounds, anthocyanins, and gene expression.

Summary: This study revealed that the predominant flavonoid compounds in the skin of red mango cultivars 'Ruby' and 'Sensation' are quercetin-3O-glucoside, cyanidin-3-O-galactoside, procyanidin B1, and procyanidin B3. Bagging treatment inhibited the biosynthesis of flavonol and anthocyanin, but promoted the accumulation of proanthocyanidin. Matured 'Ruby' fruit skin showed light red pigmentation with a light-independent anthocyanin accumulation pattern.

Summary: This study identified a transcription factor FaMYB10L that regulates anthocyanin accumulation in strawberry vegetative tissues and is induced by light. FaMYB10L upregulates the expression of anthocyanin biosynthesis-related genes and transport genes, and interacts with bHLH3 to promote anthocyanin accumulation. These findings enrich the light-involved regulatory network of anthocyanin metabolism in cultivated strawberries.

Summary: This study investigates the effects of red- and blue-light irradiation on anthocyanin accumulation in strawberry. The results show that blue light, rather than red light, promotes the rapid accumulation of anthocyanins. It is discovered that the blue light photoreceptor FaCRY1, an E3 ubiquitin ligase FaCOP1, and light-responsive factor FaHY5 play important roles in regulating blue light-induced anthocyanin accumulation.

Summary: The metabolome of strawberries at harvest determines their storage capacity. Dynamics of volatile production during storage of strawberries grown under different drainage ratios were evaluated. Various non-target VOCs analysis showed that aldehydes content decreased over the storage period, while the esters and furanones increased as aroma compounds in strawberry ripening. The release of VOCs linked to fruit decay was delayed in the groups given relatively little water. Changes in firmness, total soluble solid content, anthocyanin content, and antioxidant activity supported the slower over-ripening tendency of the groups with less water. The study demonstrated that preharvest drainage changes during cultivation affected fruit quality during strawberry storage, and optimal drainage ratio could delay stress and senescence, ensuring strawberry yield. VOCs could be considered an early indicator for strawberry fruit shelf-life.

Summary: This experiment investigated the effects of different spectra of complementary light on the growth and development of strawberry plants under salt and alkaline stress conditions. Blue and red light had the greatest effect in reducing stress, and blue/red and white/yellow light had the greatest effect on reproductive traits. Stress conditions increased sodium uptake and decreased potassium, calcium, magnesium, and iron uptake.

Summary: The presence of desmoplasia in pancreatic ductal adenocarcinoma (PDAC) is associated with poor treatment outcomes and reduced drug delivery. By analyzing collagen subtypes in PDAC tumors following different treatment regimens, immunofluorescence profiling can predict long-term survival and tumor growth inhibition. This information can aid in personalized treatment and improve patient survival.

Summary: Thin film coatings with potent antibacterial properties are widely used in medical devices, frequently touched surfaces, and food packaging. However, achieving antibacterial performance under both light and dark conditions remains a challenge. In this study, we successfully prepared AgBr-coated ZnO nanorod thin film architecture using a unique surfactant-mediated solution-phase spin-coating approach. The resulting structures showed dual functionality as antimicrobial agents and photosensitizers, effectively enhancing the visible-light photodisinfection efficacy of ZnO nanorods. The concentration of the surfactant-based precursor solution could be modulated to control the AgBr content. Additionally, components like urea and lactic acid were found to enhance the photocatalytic efficiency of the structures.
