Summary: In this study, it was found that VvBBX44 and VvMYBA1 form a transcriptional feedback loop to regulate anthocyanin biosynthesis in grapevine. VvBBX44 inhibits the transcriptional activity of VvMYBA1 and VvUFGT, preventing excessive accumulation of anthocyanin.

Summary: Anthocyanins are crucial for the color and quality of grape berries and wine. The transcriptional regulator VvMYBA1 is responsible for the coordinated expression of genes in the anthocyanin pathway. This study identifies an alternative splicing variant of VvMYBA1, VvMYBA1-L, which negatively regulates anthocyanin accumulation and fruit coloration in grapes. The interaction between VvMYBA1-L and VvMYBA1 plays a role in this regulation.

Summary: The study demonstrated that foliar application of KH2PO4 could increase total soluble solids, flavonoid, and total anthocyanin contents in grape skin. Additionally, T2 treatment resulted in lower acidity and higher pH in grape juice, as well as darker skin color compared to other treatments.

Summary: Transposition of transposable elements can affect the expression, splicing, epigenetic status, and function of genes located near the inserted/excised locus. In grape, the presence of the Gret1 retrotransposon in the promoter region of the VvMYBA1a allele suppresses the expression of the VvMYBA1 transcription factor gene, resulting in the green berry skin color of the 'Shine Muscat' grape cultivar in Japan. By targeting Gret1 with CRISPR/Cas9, we successfully eliminated the transposon in 19 out of 45 transgenic plants, demonstrating the potential for transposon removal through genome editing.

Summary: The study showed that different light qualities have varied effects on grape berry quality, with blue light increasing anthocyanins and sugars, and reducing organic acids, while red light had the opposite effect. Transcriptomics and metabolomics analyses identified differentially expressed genes and significantly changed metabolites related to photosynthesis and flavonoid biosynthesis. Weighted gene co-expression network analysis revealed modules associated with anthocyanins and soluble sugars. These findings provide insights into using supplemental light to improve fruit quality.

Summary: By analyzing agronomic traits and sequencing data, the differences between cultivated and wild grapes and peaches were compared in terms of fruit size, flavor, resistance, and color. Cultivated varieties showed advantages in fruit size, sugar content, and sugar-acid ratio. Wild varieties had utility value in terms of resistance. The study identified differentially expressed genes in cultivated and wild grapes and peaches, with some common genes between them.

Summary: In order to cultivate different grape varieties according to market needs, it is important to study the regulation mechanism of color changes in grapes at different development stages. This study used RNA-sequencing technology to compare and analyze the transcriptome data of four grape varieties at the same development stage. The anthocyanin synthesis pathway in the flavonoid pathway was mainly studied among the annotated differential genes. The role of the MYB transcription factor MYB2 in anthocyanin regulation was confirmed through subcellular localization and gene function verification.

Summary: A study found 27 genes highly related to variegated testa color synthesis in peanuts, with 13 up-regulated and 14 down-regulated genes mainly involved in the flavonoid metabolism pathway. Validation through different methods showed that color differences in different areas are primarily caused by metabolites such as cyanidin and delphinidin.

Summary: Anthocyanins are important secondary metabolites in plants, which determine the color of flowers and fruits. They have various nutritional and medicinal functions, such as antioxidant, anticancer, and cardiovascular disease prevention. This review discusses the biosynthesis pathway of plant anthocyanins, the key structural genes involved, the impact of transcription factors and microRNAs, the influence of environmental factors, and the effects of six major exogenous hormones on anthocyanin synthesis and metabolism. Future research directions and trends in anthocyanins are also considered to provide a reference for future studies and applications.

Summary: In this study, the roles of MYB family in blueberry in response to anthocyanin biosynthesis were explored. A total of 437 unique MYB sequences were identified and characterized in blueberry, and their transcriptional patterns during fruit development and fruit tissues related to anthocyanin biosynthesis were investigated. The results provide valuable insights into the functional roles of VcMYBs and their regulatory mechanisms for anthocyanin production and accumulation in blueberry.

Summary: Cis- and trans-regulatory variations play distinct roles in lotus flower color evolution, with trans-regulatory mutations having a stronger impact on expression differences between species. In F1 hybrids, genes under cis-only and trans-only regulatory effects show different modes of inheritance, with additive and dominant inheritance respectively. The relative abundance of genes in different categories of regulatory divergence is associated with expression level and breadth constraints.
