Popis: Floral scent plays a vital role in reproduction, including attracting pollinators to ensure that fertilization occurs in several plants. In addition, floral scents are widely applied in perfumes, flavors, cosmetics and medicinal substances. Floral scents mediate ecological interactions and have a primary function of attracting visitors and pollinators. Due to the importance of floral scents in plant biology, basic research on flora scent through breeding technology or applications of biotechnology in is still needed. In plants, floral volatile organic compounds (VOC) are categorized into terpenoids, phenylpropanoids/benzenoids and fatty acid derivatives. Several transcription factors are involved in secondary metabolite pathways, including floral scents. Transcriptional regulation of these biosynthesis pathways involves V-myb myeloblastosis viral oncogene homolog (MYB) protein transcription factors, which play a prominent role in flowers. However, little is known about the transcriptional regulation of floral scent biosynthesis. Thus far, the engineering of the metabolic pathways responsible for producing floral scents has mainly focused on the final steps of volatile compound generation. In this review, we summarize recent research on the importance and emission of floral scents and emphasize the role of the identified MYB transcription factors in regulating floral volatile metabolism.
