Summary: This study investigated the differences in AsA content and potential mechanisms between two cultivars of hardy kiwifruit. The results showed that GalLDH is a key enzyme for AsA biosynthesis in hardy kiwifruit, while MDHAR is more efficient than DHAR in AsA regeneration. Moreover, AO and APX play important roles in AsA oxidation. This study provides a reference for further genetic improvement and selection of high AsA content materials in cultivation.

Summary: Ascorbic acid, besides its essential role in human health, also plays a regulatory function in fruit ripening. This review provides a plant physiological perspective on ascorbic acid, discussing its key regulatory points during preharvest and postharvest stages, its ability to modulate ethylene and abscisic acid signaling, and its relevance to cellular redox state and postharvest shelf-life.

Summary: In this study, a 3D transcriptome data of five different peach varieties was used to construct gene co-expression networks during fruit ripening. Comparative analysis of these networks identified modules related to organic acid synthesis and metabolism under high-acid and low-acid conditions, and 20 candidate genes were identified as regulatory factors for organic acid metabolism in peach.

Summary: Fig fruits have significant health value and cultural importance. This study identified 119 FcAP2/ERF genes and analyzed their expression patterns during fruit development and ripening. Most FcAP2/ERFs were downregulated during fruit development and ripening, suggesting a repressive role in fruit ripening. Several downregulated ERFs also had repression domains. Additionally, a few FcAP2/ERFs were differentially expressed in all three transcriptome datasets, making them promising candidates for future genetic studies on the major regulators of the superfast fig fruit ripening process.

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: This study determined the dynamic changes in ascorbic acid (AsA) content during fruit development and ripening of Actinidia latifolia and successfully constructed a high-quality, full-length transcriptome of this species. Key genes involved in AsA biosynthesis and recycling pathways were identified, and long noncoding RNAs related to AsA gene expression regulation were also discovered.

Summary: The rinG2 mutation in tomato results in fruit with extended shelf life, lower levels of ethylene production, delayed softening, and a different carotenoid accumulation profile compared to rin mutation. RinG2 represents a promising genetic resource for developing tomato cultivars with improved shelf life.

Summary: The study examines the relationship between vitamin C dose and concentration, specifically in relation to age and smoking status. It found that while vitamin C intake was similar across age groups, older individuals had significantly lower circulating vitamin C concentrations. This effect was more pronounced in non-smokers and suggests that older individuals may be more sensitive to low vitamin C intake, possibly due to the effects of long-term smoking and increased chronic disease prevalence.

Summary: Fruit ripening is a complex process regulated by various mechanisms at the posttranscriptional, translational, and posttranslational levels. These mechanisms include alternative splicing, RNA modification, noncoding RNAs, translation efficiency regulation, and protein modifications. Together with transcriptional regulation, these mechanisms constitute the molecular framework of fruit ripening and have potential implications for improving fruit traits.

Summary: This study reveals that FaMAPK5 and FaMAPK10 genes play a role in ABA-mediated strawberry fruit ripening and antioxidant capacity. Overexpression of these genes increases fruit anthocyanin, ABA, total sugar, and glucose contents, as well as enhancing the activity of antioxidants. Furthermore, the overexpression of FaMAPK5 demonstrates improved resistance against Botrytis cinerea, a common strawberry pathogen.

Summary: The topical application of vitamin C and its derivatives in skincare is essential, but there is still a lack of scientific data regarding their efficacy, especially in vivo. Studies on the stability, safety, adverse reactions, and efficacy with standardized parameters and a relevant number of subjects are necessary for better understanding their effects.

Summary: Fruit ripening is a complex process involving the coordination of genes, hormones, and environmental factors. Understanding this mechanism is crucial for improving shelf life and storage duration. However, our current understanding is limited to model organisms, and the mechanism for non-model fruits remains largely unknown.

Summary: Vitamin C plays a significant role in cancer prevention and treatment, with studies showing its potential benefits in preventing pulmonary and breast cancer, as well as its synergistic effects with pancreatic cancer drugs. However, a Mendelian randomized study did not find an association between vitamin C and cancer prevention. Ongoing research is needed to further explore the therapeutic role of vitamin C in cancer through new phase II and III clinical trials.
