Summary: In this study, a potential transcription factor OfMYB21 was identified to regulate the linalool synthetase OfTPS2 in O. fragrans, and its binding and activating effects on OfTPS2 were confirmed. Overexpression of OfMYB21 increased the expression of OfTPS2 and the accumulation of linalool, while silencing of OfMYB21 had the opposite effects. It was also found that OfMYB21 interacted with JA signaling factors OfJAZ2/3 and OfMYC2, and the interaction between OfMYC2 and OfMYB21 enhanced the transcription of OfTPS2.

Summary: Auxin, as a crucial plant hormone, induces the biosynthesis of secondary metabolites in ornamental plant Hedychium coronarium. By identifying and characterizing the transcription factors HcMYB1 and HcMYB2, it was found that they play essential roles in regulating the formation of floral scent compounds in response to auxin signaling, by interacting with key genes and proteins involved in the process.

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: Flowers emit volatiles to attract pollinators and protect themselves. Previous studies have focused on the quality and quantity of floral volatiles, while little is known about their emission patterns. This study used optical interferometry to measure the emission frequency of lily flowers and found that they emit volatiles discontinuously.

Summary: Floral scent plays a crucial role in maintaining ecological equilibrium and has significant implications for human well-being. Research on floral scent has seen a rapid increase, particularly in the fields of food science technology, plant sciences, and chemistry. The focus of research has shifted from the exploration of individual pollination ecological functions to the holistic evaluation of floral scent's impact on species diversity and ecosystem stability.

Summary: This study investigates how the capitulum of Chrysanthemum morifolium balances the accumulation and emission of floral terpenoid volatiles for defense against antagonists and attraction of pollinators. The results show that the capitula produce and emit complex mixtures of monoterpenoids and sesquiterpenoids, with the highest concentrations detected in the bud stage and the highest emission level prior to full blooming. The disc florets are the dominant organs of terpenoid accumulation and emission in the full-openness stage. Several key terpene synthase genes have been identified, which may play critical roles in terpenoid biosynthesis.

Summary: This study used RNA-Seq to identify candidate genes associated with differential production of the floral volatile (R)-(-)-linalool in Oenothera harringtonii. The results showed tissue-specific upregulation of terpene synthase genes in plants that produce (R)-(-)-linalool and identified two putative (R)-(-)-linalool synthase transcripts. Additionally, other terpene biosynthesis-related genes that are up-regulated in plants that emit (R)-(-)-linalool may be associated with herbivore defense.

Summary: Volatile organic compounds play a significant role in communication within biological systems. A method for experimental manipulation of these compounds is described, using silicone rubber to control scent emission. The results show that the method allows for repeatable and adjustable emission rates of volatiles.

Summary: By analyzing the metabolome and transcriptome of Chrysanthemum indicum var. aromaticum (CIA) flowers at different developmental stages, this study identified 370 volatile metabolites, mainly terpenoids and esters, and 8,945 differentially expressed genes. Enrichment analysis revealed candidate genes associated with the biosynthesis of phenylpropanoids, esters, and terpenes. The study also found that the expression of volatile terpene-related genes was regulated by specific transcription factors. These findings provide insights into the molecular mechanisms of floral scent metabolite biosynthesis and offer valuable data for molecular breeding and utilization of CIA plants in the future.

Summary: The study found that down-regulating the CcLBD25 gene may affect the initiation and development of dodder parasitism, leading to stress on parasitic plants growing on hosts. Furthermore, reducing the expression of the CcLBD25 gene through host-induced gene silencing may aid in developing parasite-resistant crops.

Summary: Floral volatiles play an important role in plant-pollinator interactions. Understanding these interactions, especially in arid regions, is crucial as pollinator scarcity and abiotic stress factors like water shortage can limit the reproductive success of plants. This study focused on Matthiola livida and found that water shortage and insect herbivory caused stress in the plants, leading to changes in their floral volatiles. Bumblebees were able to differentiate between stressed and non-stressed plants based on their volatile composition, showing that pollinators are sensitive to plant conditions and use floral volatiles in their foraging decisions.
