Summary: Rosmarinic acid (RA) treatment in postharvest significantly delayed ripening, reduced ethylene production, inhibited color change, promoted amino acid accumulation, and enhanced antioxidant activity in tomato fruits. These findings indicate a novel function of RA in fruit ripening, offering an attractive strategy to manage and improve the quality of tomato fruits.

Summary: This study investigated the effects of selenium enrichment on tomato ripening and found that selenium had an impact on metabolic processes and the biochemical composition of ripe tomatoes. The changes in metabolites may be due to the influence of selenium treatment on gene expression.

Summary: This study investigated the effects of enriching tomatoes with selenium during the last stages of fruit development, particularly ripening. Selenium enrichment had no significant effects on ethylene production or color changes in the ripening fruit but influenced the biochemical composition of ripe tomatoes. Selenium decreased beta-carotene content, increased naringenin and chlorogenic acid accumulation, and decreased coumaric acid level. It also affected the volatile organic compound profile, including specific apocarotenoid compounds. RNA-seq analysis showed that selenium treatment mainly impacted gene expression related to hormonal signaling, secondary metabolism, flavonoid biosynthesis, and glycosaminoglycan degradation.

Summary: This review discusses the recent advances in epigenetic regulation of tomato fruit ripening, including DNA methylation, N6-Methyladenosine mRNA modification, histone demethylation/deacetylation, and non-coding RNA. This research contributes to a better understanding of the regulatory mechanisms governing tomato fruit ripening and provides new insights for precise modulation of these mechanisms.

Summary: Fruit ripening is regulated by transcription factors, plant hormone ethylene, and DNA methylation. DNA methylation affects fruit ripening by transferring methyl groups. Tomato fruit ripening is dynamically regulated by DNA methylation and demethylation, but the specific molecular mechanism is still unclear.

Summary: In this study, the application of difenoconazole on tomato plants was found to increase soluble sugar content, reduce organic acid, and raise accumulation of nutrient-related metabolites. Consumer surveys showed that difenoconazole-treated tomatoes had higher sweetness and lower acidity, and were preferred by consumers. The study also identified the mechanisms by which difenoconazole affects fruit flavor quality through the regulation of sucrose and organic acid metabolism, as well as phytohormone synthesis.

Summary: The study identified the MaMADS36 transcription factor gene as a crucial regulator in banana fruit, controlling processes like ethylene biosynthesis, starch degradation, softening, and sugar accumulation. MaMADS36 was found to directly interact with the MaBAM9b gene, enhancing its transcription activity and influencing starch degradation during fruit ripening.

Summary: The study investigates how brassinosteroids (BRs) regulate fruit ripening in tomato and their interactions with ethylene. It is found that BR treatment and increased endogenous BR contents promote ethylene production and fruit ripening. The BR signaling regulators SlBZR1 and SlBES1 redundantly act in fruit softening. Knocking out SlBZR1 inhibits ripening through transcriptional reprogramming. SlBZR1 directly targets ethylene and carotenoid biosynthetic genes, contributing to ethylene burst and carotenoid accumulation for normal ripening and quality formation. Overall, SlBZR1 is highlighted as a master regulator of tomato fruit ripening with potential for quality improvement and carotenoid fortification.

Summary: The study verified that tomato SIPP2CS acts as a negative regulator in ABA signaling during fruit development. SIPP2C5 interacts with ABA receptors and kinases to regulate fruit development, maturation, and quality parameters. Overexpression or suppression of SIPP2C5 alters plant sensitivity to ABA and affects fruit ripening time.
