Summary: Flavonoids are important secondary metabolites in plants, regulated by MYB transcription factors. The study identified that the MYB activator MYB117 can enhance anthocyanin accumulation in hybrid poplar by up-regulating F3'5'H1, resulting in increased B-ring hydroxylation.

Summary: In this study, the MazsF3H gene was cloned and characterized from Morus atropurpurea var. Zhongshen 1, and its important role in the accumulation of anthocyanin in fruits was discovered. The expression levels of F3H varied in different mulberry varieties, possibly related to fruit color. Overexpression of MazsF3H in tobacco resulted in decreased anthocyanin content, while down-regulation of F3H expression levels led to a significant decrease in anthocyanin content.

Summary: Anthocyanins play a crucial role in determining flower color diversity in angiosperms, with differential expression of specific structural and regulatory genes identified in blue- and orange-petaled individuals of Lysimachia arvensis. The shift from blue to orange petals is associated with changes in expression of key genes involved in anthocyanin biosynthesis pathway, as well as amino acid substitutions in enzymes affecting substrate specificity. This study highlights the complex genetic and physiological consequences of flower color polymorphism in L. arvensis.

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.

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: In this study, lncRNAs in the southern highbush blueberry were identified using strand-specific RNA sequencing. The findings showed that blueberry lncRNAs had distinct characteristics compared to protein-coding RNAs and exhibited stage-specific expression patterns during fruit development. The study also revealed that lncRNAs may play important roles in fruit expansion and ripening in blueberries.

Summary: In this study, a new color variant of wild soybean with pinkish-white flowers was isolated, and it was found that the pinkish-white color was caused by a single recessive allele of W1. A SNP detected in the mutant led to an amino acid substitution in a highly conserved domain of F3'5'H proteins, resulting in hypofunctional F3'5'H activity and the pinkish-white color of the flowers.

Summary: The study conducted RNA-seq and de novo assembly of flower tissues from five Rhododendron species, revealing that different genes regulate flower color variation in different species. The species were clustered into two main groups based on the expression levels of differentially expressed genes (DEGs), with Rhododendron molle showing a closer relationship with R. simsii. This research provides valuable genetic information for further analysis of flower color variation and genetic improvement in Rhododendron species.

Summary: The study analyzed the flower color and pattern of 110 carnation cultivars, categorizing them into five typical types and two minor types, with the typical types further classified into 16 sub-types. The carnations were found to have 15 hues, determined by the combination of specific anthocyanins, chalcononaringenin 2'-O-glucoside, and chlorophyll. This diversity in flower color characteristics is influenced by the formation of anthocyanin aggregates and cell shape in the petal epidermis, leading to various color perceptions.

Summary: This study found that S. littorea is mainly pollinated by bees and butterflies, with pollinators showing a preference for visiting pink flowers. White flowers exhibited pollinator limitation in fruit set and higher levels of florivory. Both flower colour morphs can reproduce in the absence of pollinators through autonomous selfing, but white flowers mainly produce fruits through autogamy.

Summary: The timing of flowering is a critical trait in legume plants, and identifying the genes associated with this process is essential for further genetic studies. Through translational genomics from model legume crops, QTLs linked to flowering time in faba bean were successfully identified, providing a robust framework for genetic research. The study also suggests the important role of epigenetic modifications in controlling flowering time in faba bean.

Summary: The phenotypic plasticity in many flowers allows for rapid exploration of different regions of the floral morphospace. Moricandia arvensis exhibits a greater floral disparity driven by plasticity than that found between species, genera, and tribes, with its novel phenotype moving outside the region occupied by its ancestors and relatives, converging with distant Brassicaceae lineages, and encountering a different pollination niche. This suggests that phenotypic plasticity favors floral divergence and rapid appearance of convergent flowers, facilitating the evolution of generalist pollination systems.

Summary: Flower colour is determined by the presence and type of pigments, with pollinator preferences influencing selection pressure on flower colour. Understanding how pollinators perceive flowers with different pigments is crucial for plant-pollinator communication and flower colour evolution. Research shows that different pigment groups occupy distinct regions in pollinator colour space models, with similar differences in colour conspicuousness among the groups in bee, fly, butterfly, and bird visual space models.

Summary: Plasticity can have direct effects on the interactions between species, by expanding or shifting interaction niches, and ultimately modifying the structure and functionality of ecological networks. This causal pathway may explain how interaction niches evolve quickly in response to rapid environmental changes and is important for understanding the impact of global change on ecological interactions.
