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: DNA acetylation plays a role in regulating gene expression during plant development, including in grapes. In this study, 'Kyoho' grapes treated with a deacetylase inhibitor were used to investigate the effects of acetylation. The results showed that acetylation positively regulated phenylalanine metabolism and flavonoid biosynthesis pathways. The research also revealed the interactions between transcription factors and histone deacetylases, highlighting the importance of histone modification in anthocyanin biosynthesis and grape ripening.

Summary: The study utilized the CRISPR/Cas9 gene-editing system to generate a sl_hta9 sl_hta11 double mutant, designated sl_h2a.z, which significantly reduced the fresh weight of tomato fruits. mRNA-seq results showed that Sl_H2A.Z dysfunction has profound effects on genome-wide gene expression in tomato fruits at different developmental stages, with a ripening-dependent correlation between Sl_H2A.Z and gene expression regulation. Additionally, the upregulation of key genes in the carotenoid biosynthesis pathway in the late ripening stages of sl_h2a.z mutant fruits was consistent with increased carotenoid contents, revealing a role of Sl_H2A.Z in carotenoid regulation and providing insights into histone variants' regulation of tomato fruit quality.

Summary: This study found that the application of magnesium fertilizer can significantly increase the magnesium content in Satsuma mandarin pulp, increase the soluble solids content, and decrease the acidity. In addition, magnesium treatment also increased the carotenoid content in the pulp, possibly due to the increased expression of related genes.

Summary: Carotenoids are important components in mango fruits, and their content and metabolic gene expression vary among different cultivars. Regulation of carotenoid metabolism in mango primarily occurs at the transcriptional level, with differential gene expression patterns influencing carotenoid accumulation in fruits. Variability in carotenoid content among mango cultivars is attributed to differential regulation of both biosynthetic and catabolic carotenoid genes.

Summary: This study reveals the presence of non-histone lysine methylation in tomato fruit ripening, which may participate in the regulation of fruit ripening. A total of 241 methylation sites were identified by LC-MS/MS, and these methylated proteins were found to be associated with fruit ripening, senescence, signal transduction, and other processes.

Summary: Fruit ripening and softening is a complex process regulated by a wide range of genes, and histone modification plays a critical role in precise gene expression. This study identified a NAC transcription factor MaNAC154 as a negative regulator of banana fruit ripening and found its interaction with a histone deacetylase MaHDA6 to enhance transcriptional repression capacity, revealing a coordinated mechanism involving histone deacetylation and transcription factor-mediated gene repression for banana fruit ripening.

Summary: This study investigated the effects of red, blue, and white light-transmittance bagging on carotenoid metabolism during 'Moro' blood orange ripening. The results showed that red light-transmittance bagging increased the esterification of easily absorbed xanthophylls and promoted carotenoid accumulation.

Summary: The study reveals that SlJMJ7 acts as a critical negative regulator of fruit ripening in tomato, regulating the expression of ripening-related genes through the removal of H3K4me3 and DNA demethylation. These findings highlight the importance of the crosstalk between histone methylation and DNA methylation in plant developmental processes.

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.
