Summary: The ripening of tomato fleshy fruit is coordinated by the transcription factor RIN, which triggers various metabolic processes. Different tomato cultivars and wild species show variations in the RIN gene locus and genotype, leading to differences in gene expression and function related to fruit ripening. RIN1 activates ripening-related genes, while RIN2 and RIN-MC act as modulators by competing for RIN-binding sites in gene promoters.

Summary: This study investigated the role of H2O2 in tomato ripening and found that H2O2 participates in this process through its association with the ethylene signaling pathway. The experiments showed that high irradiance treatment enhanced H2O2 production and accelerated fruit ripening. These results may be attributed to changes in the expression of H2O2-related genes and ethylene-related genes.

Summary: In this study, a tomato methionine synthase named SlMS1 was found to play a positive regulatory role in tomato fruit ripening. Further investigation showed that SlMS1 could up-regulate the expression of genes related to carotenoid synthesis, chlorophyll degradation, cell wall metabolism, and ethylene synthesis pathway, thereby promoting fruit ripening. These findings provide important insights into the molecular mechanism of tomato fruit ripening.

Summary: The study found that NO has a significant impact on the ripening process of tomato fruit, including regulating ripening-related genes, affecting metabolite content, and limiting ethylene production. Additionally, NO intensified oxidative stress and nitro-oxidative events, impacting the biosynthesis of compounds such as ascorbate, flavonoids, and lycopene.

Summary: The bZIP transcription factor SlTGA2.2 plays an important role in the growth and maturation of tomato fruits. By targeting the expression of a chimeric repressor, the study found that the repressor affects fruit development and metabolism, prolongs the time to reach maturity, and slows down fruit ripening. This research provides a useful tool for studying the molecular bases of tomato fruit transition to ripening.

Summary: Previous study finds that SNAC4 and SNAC9 have opposite effects on carotenoid biosynthesis and softening in tomato fruit ripening. Using an overexpressing system, this study explores the regulatory mechanism of SNAC4/9 in tomato fruit ripening and softening. The results show that the overexpression of SNAC4 and SNAC9 accelerates fruit ripening, promotes ethylene biosynthesis and carotenoid accumulation, but has different effects on ABA content and fruit firmness.

Summary: The practices of ripe and pre-ripe harvesting have significant effects on fruit quality. The synthesis and accumulation of health-promoting bioactive compounds in fleshy fruits are influenced by light quality and intensity. Phytochromes and their signaling networks play crucial roles in connecting light perception and the accumulation of antioxidants. In tomato, a mutation in PHYTOCHROME 2 (SlPhyB2) can confer light-independent activation. Overexpressing native SlPhyB2 or the constitutively active allele SlYHB2 in tomato fruits delays on-vine ripening and sustains high carotenoid and tocopherol synthesis even under dark conditions. These findings demonstrate the importance of adjusting PHY properties to minimize penalties in carotenoid and tocopherol accumulation in tomato fruits due to suboptimal harvesting and storage conditions.

Summary: Temperature stress negatively affects fruit set and growth in tomatoes. The localization of auxin in the ovaries and peduncles, which affects fruit set and growth, is disturbed by short-term high-temperature stress. On the other hand, low-temperature stress does not significantly affect fruit set, but causes a delay and recovery of fruit growth.

Summary: The all-flesh type of tomato fruits is caused by mutation of the MBP3 gene, however, knocking down MBP3 in certain genotypes also affect plant and fruit development. Here, the authors show that a natural mutation of AGL11, a close homolog of MBP3, is responsible for the phenotypic divergence.

Summary: This study reveals that SlERF.F12, an ethylene response factor, negatively regulates the initiation of tomato fruit ripening by recruiting a co-repressor and histone deacetylases. SlERF.F12 interacts with the co-repressor and recruits histone deacetylases to form a complex, which decreases the acetylation level at the promoter regions of ripening genes, thus repressing their transcription.

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: The study identified five Ethylene Response Factor (ERF) genes in the cDNA library of Hevea latex, with HbERF-IXc4 showing the strongest transactivation capacity and being most frequently screened. These ERFs mainly localized in the nucleus and four of them exhibited apparent transactivation activity. This indicates the critical involvement of ERFs, especially HbERF-IXc4, in the activation of HbSUT3 expression in latex after Ethrel treatment and the stimulated latex yield.
