Summary: Light is a crucial environmental factor that affects the production of anthocyanin. Proper regulation of light conditions can enhance the ornamental and economic value of ornamental plants. The study on tree peonies reveals that light not only influences flower color and quality, but also their ornamental value in specific environments. However, the molecular mechanism of how light regulates the biosynthesis of anthocyanin remains unclear.

Summary: This study investigated the physiological and biochemical factors affecting the color of herbaceous peony petals. By analyzing the changes in flower color, petal area, and microstructure, as well as the composition and content of pigments, soluble sugar and protein, pH value of cell fluid, and water content, the study found that changes in anthocyanin and carotenoid content in petals directly caused the change in herbaceous peony flower color. Other physiological indices also contribute to the change in flower color. The findings have important practical significance for understanding the physiological mechanism of herbaceous peony flower color formation and breeding new flower varieties.

Summary: Temperature affects anthocyanin synthesis in chrysanthemum, leading to color fading. High-temperature stress induces differential gene expression related to heat shock response and flavonoid pathways, contributing to the fading of flower color. Genes involved in anthocyanin synthesis and heat shock response show differential expression under high-temperature stress.

Summary: The study identified a key transcription factor, PrASIL1, in tree peony seed oil accumulation, which represses oil accumulation by down-regulating numerous key genes during biosynthesis. Silencing the PrASIL1 gene led to up-regulation of oil biosynthesis genes and an increase in total lipids and major fatty acids. These findings provide new insights into controlling seed oil accumulation.

Summary: In comparison to Magnolia biondii, the variety M. biondii var. purpurascens exhibited higher anthocyanin content and expression levels of genes involved in flavonoid biosynthesis. This difference in color was attributed to variations in petal color phenotypic parameters, flavonoid composition, and gene expression levels between the two Magnolia plants. These findings lay the foundation for understanding flower color evolution in Magnolia plants.

Summary: This study aims to investigate the potential function of heat shock factors (HSFs) in the regulation of floral scent in petunia. The results showed that petunia contains 34 HSF gene family members, with 23 belonging to the HSFA subfamily. It was found that the expression pattern of PhHSF19 is positively related with PhPAL2, and the yeast one hybrid and dual luciferase assays confirmed that PhHSF19 positively regulates the expression of PhPAL2. These results lay a theoretical foundation for further studies of the regulation of HSFs on plant flower scent biosynthesis.

Summary: The petal color in Zinnia elegans is determined by the accumulation of anthocyanins, especially cyanidins. The transcription factor ZeMYB9 from subgroup 6 was identified as a positive regulator of anthocyanin accumulation, and it can activate the expression of ZeF3'H, enhancing cyanidin synthesis and regulating petal color in Z. elegans. ZeMYB9 was also found to interact with the bHLH transcription factor ZeGL3, further promoting the promoter activity of ZeF3'H and inducing anthocyanin accumulation in tobacco leaves.
