Summary: Deastringency treatment of persimmon fruit causes severe damage to membrane integrity, with CO2 treatment promoting gene expression related to membrane deterioration and increasing fruit respiration and ethylene release rates. The addition of 1-MCP can reduce membrane damage but delays the deastringency process.

Summary: The structure of persimmon peel proanthocyanidins (PPPAs) was characterized, revealing the composition units and linkages present. The degree of polymerization and galloylation were also determined. These findings are important for a better understanding of the proanthocyanidins in persimmon peel and their biological activities.

Summary: The aim of this study was to evaluate the characteristics of nine kaki vinegars produced using different yeasts and bacteria traditionally involved in wine production, and to assess their acidity, density, total phenolic content, and antioxidant activity. The study also analyzed the volatile fingerprinting of the vinegars using two different techniques and characterized the carotenoids present in each vinegar. The results showed that vinegars fermented with S. cerevisiae produced a larger number of volatile chemicals, and the vinegar fermented with Acetobacter_vino had a more complex flavor profile. Only the vinegar produced using a mixture of T. delbruekii and Acetobacter had a high concentration of carotenoids.

Summary: This study investigated the involvement of effectors and transcriptional regulators in persimmon fruit maturation by analyzing the expression of genes involved in ethylene biosynthesis and response pathways. Results showed different gene expression patterns during fruit development, with some genes up-regulated and some genes down-regulated. The study also identified molecular mechanisms for high ethylene production in immature fruits and for fruit softening and skin colour change during natural ripening.

Summary: Persimmons, a short-shelf-life fruit, were subjected to different pretreatments before convective drying, showing that PVOD and US pretreatments led to the shortest drying times. The study revealed that pretreatments can alter the characteristics of the dried fruits, with Fick's model being the most appropriate for fitting the drying kinetics.

Summary: Pectins are important components of plant cell walls. This study identified multiple putative DkPMEs and DkPMEIs in the persimmon genome and classified them into different clades based on phylogenetic analysis. These genes were found to be highly conserved within the same clades, indicating similar functions. Furthermore, the distribution of these genes on chromosomes was uneven. Expression analysis showed diverse expression patterns within the same clade, suggesting diverse functions. Protein-protein interaction network analysis revealed core nodes involved in carbohydrate metabolism, stress responses, and sugar signaling. This study provides important insights into the functional characteristics, evolutionary relationship, and role of these gene families in persimmon fruit development.

Summary: The use of visible and near-infrared (Vis-NIR) spectroscopy as a non-destructive and environmentally-friendly alternative to elemental analyses for crop nutritional diagnosis was investigated. The concentrations of macronutrients and micronutrients in persimmon leaves were estimated using Vis-NIR spectroscopy, showing promising results. This technique could be used as an alternative to conventional laboratory methods for diagnosing the nutritional status of persimmon trees.

Summary: This study developed an efficient transformation system and in vivo regeneration protocol for persimmon. RNA interference of DkANR gene was successfully achieved, resulting in a decrease in proanthocyanidin accumulation. The reliable and highly efficient transformation system achieved in this study may contribute to gene function identification and genetic improvement in persimmon.

Summary: Research on crop sexuality is vital for germplasm innovation and variety improvement. This study investigated the effects of ethrel and zeatin on androecious persimmon trees, finding that both significantly affected stamen length and pollen grain diameter. The treatments also impacted carbohydrate, amino acid, and phytohormone contents, as well as genes associated with hormone production and floral organ development. Additionally, a combination of chemicals inhibited flower development and revealed complex regulatory mechanisms. These findings contribute to our understanding of sexual differentiation in persimmons and provide a theoretical basis for molecular breeding and quality improvement.
