Summary: In this study, transcriptome and metabolome analyses were conducted to understand the formation mechanism of different flower colors in Cymbidium ensifolium. The results revealed differences in metabolites and expression levels of anthocyanin biosynthetic enzyme genes in different colored sepals. Key genes involved in anthocyanin production and the important role of CeMYB104 in flower color formation were also identified.

Summary: Cyanidin-3-[2 ''-(6 '-coumaroyl)-glucosyl]-glucoside was identified as the major anthocyanin in black fruit of Nitraria sibirica Pall.. NsMYB1 was found to be a functional R2R3-MYB transcription factor that regulated anthocyanin biosynthesis and caused the fruit color differentiation in Nitraria sibirica Pall.

Summary: Ethylene induces anthocyanin biosynthesis in most fruits, but inhibits it in pears. The transcription factor PpERF105 activated the expression of PpMYB140, which then inhibited the anthocyanin biosynthesis in pears. The competition between PpMYB140 and PpMYB114 led to the formation of a complex that further inhibited anthocyanin biosynthesis.

Summary: This study identified a transcription factor FaMYB10L that regulates anthocyanin accumulation in strawberry vegetative tissues and is induced by light. FaMYB10L upregulates the expression of anthocyanin biosynthesis-related genes and transport genes, and interacts with bHLH3 to promote anthocyanin accumulation. These findings enrich the light-involved regulatory network of anthocyanin metabolism in cultivated strawberries.

Summary: Anthocyanins are important flavonoid pigments involved in the coloration of flowers and fruits. ScGST3, an anthocyanin-related GST, was identified and found to play a crucial role in anthocyanin accumulation in cineraria. Silencing ScGST3 in cineraria leaves inhibited anthocyanin accumulation, confirming its function in anthocyanin transport.

Summary: This study identified the pigment basis and key factors involved in blotch formation in tree peony. The MYB transcription factor PsMYB30 was found to activate the expression of anthocyanin biosynthesis genes, promoting petal blotch formation. Targeting PsMYB30 could reduce the size and color intensity of blotches, providing new insights into petal blotch formation in plants.

Summary: This study investigated the molecular mechanisms of fruit color formation in different cultivars of Kadsura coccinea. Metabolomics and transcriptomics analysis revealed differential anthocyanin accumulation levels and gene expression patterns between the cultivars. A key anthocyanin activator, KcMYB1, was identified and found to be closely related to anthocyanin accumulation.

Summary: Through weightage gene coexpression network analysis, a network of 15 hub genes related to the flavonoid biosynthetic pathway in peach flowers was identified, with MYB108 playing a crucial role in activating PpDFR. Additionally, the insertion of MYB binding site in the core promoter region of PpDFR in red flowers and its positive interaction with PpMYB108 further supported the role of PpMYB108 as a transcriptional activator for anthocyanin biosynthesis.

Summary: This study identified a total of 136 CeMYB transcription factors from C. ensifolium, which belong to different subfamilies and are distributed on 18 chromosomes. The analysis showed that CeMYBs may have various biological functions and play a role in flower color variation. Further investigations are needed to understand the potential function of CeMYB genes in anthocyanin biosynthesis.

Summary: Research on Pistacia chinensis revealed that R2R3-MYB proteins play a crucial role in anthocyanin biosynthesis and autumn leaf coloration. By conducting genome-wide analysis of transcription factors, PcMYB113 was identified as a key gene with the highest correlation to anthocyanin accumulation, promoting the accumulation of anthocyanin in leaves.

Summary: This study identified a predicted transcription factor, PpMYB39, associated with anthocyanin biosynthesis in peach fruit through comparative transcriptome analysis. The highest expression level of PpMYB39 was found at the stage where the maximum amount of anthocyanin accumulated. The study also revealed the possible role of PpDFR as a transcriptional activator of MYB39.

Summary: Evolutionary genetic studies have revealed genomic hotspots and biased patterns of mutations in phenotypic evolution. Using a computational approach to study the anthocyanin pigmentation pathway, it was found that evolutionary changes concentrate at hotspot loci but the type and order of mutations depend on the evolutionary context.
