“…Eridictyol, myricetin, prunetin and glycerin content were the highest at the bud stage. For rose, flavonoid content was also highest at the full open flower stage ( Kanani et al, 2021 ). These results suggest that flower is a valuable source of flavonoids to promote human health.…”

“…As a result of population and universality in omics technologies, there are many studies on metabolomics analysis of different flower colors and transcriptomic analysis during flower development. For Rosaceae , flower flavonol, and anthocyanin distribution, phenolic content changes during flower development have been studied ( Schmitzer et al, 2010 ; Kanani et al, 2021 ). For Rhododendron species, transcriptome analysis at different flower development stages and characterization of anthocyanins and flavonoids underlying flower color divergence have been conducted ( Du et al, 2018 ; Xia, Gong & Zhang, 2022 ; Ye et al, 2021 ).…”

The azalea (Rhododendron simsii Planch.) is an important ornamental woody plant with various medicinal properties due to its phytochemical compositions and components. However little information on the metabolite variation during flower development in Rhododendron has been provided. In our study, a comparative analysis of the flavonoid profile was performed in Rhododendron pulchrum sweet at three stages of flower development, bud (stage 1), partially open flower (stage 2), and full bloom (stage 3). A total of 199 flavonoids, including flavone, flavonol, flavone C-glycosides, flavanone, anthocyanin, and isoflavone were identified. In hierarchical clustering analysis (HCA) and principal component analysis (PCA), the accumulation of flavonoids displayed a clear development stage variation. During flower development, 78 differential accumulated metabolites (DAMs) were identified, and most were enriched to higher levels at the full bloom stage. A total of 11 DAMs including flavone (chrysin, chrysoeriol O-glucuronic acid, and chrysoeriol O-hexosyl-O-pentoside), isoflavone (biochanin A), and flavonol (3,7-di-O-methyl quercetin and isorhamnetin) were significantly altered at three stages. In particular, 3,7-di-O-methyl quercetin was the top increased metabolite during flower development. Furthermore, integrative analyses of metabolomic and transcriptomic were conducted, revealing that the contents of isoflavone, biochanin A, glycitin, and prunetin were correlated with the expression of 2-hydroxyisoflavanone dehydratase (HIDH), which provide insight into the regulatory mechanism that controls isoflavone biosynthesis in R. pulchrum. This study will provide a new reference for increasing desired metabolites effectively by more accurate or appropriate genetic engineering strategies.

“…According to current climate prediction models, plants are subject to stronger environmental stresses, such as salinity, drought, and mineral deficiency [22]. Furthermore, stress factors frequently exert opposing selective pressures on specific floral characteristics such as pigmentation, nectar content, and aroma [23]. Drought stress is one of the most serious stresses and it is known to harm horticultural produce, including floriculture.…”

“…In addition to the evidence of reduced growth and yield losses, drought stress also impacts the biosynthesis of secondary metabolites [24,25]. They are necessary for the plant to interact with its environment for adaptation and defence against viruses, parasites, and herbivores, but do not play a fundamental role in the maintenance of life processes in plants [23,24]. Terpenes, phenolic acids, flavonoids, alkaloids, tannins, and VOCs represent the principal secondary metabolites commonly found in plants mboxciteB26-plants-2613533,B27-plants-2613533,B28-plants-2613533.…”

Roses are popular ornamental plants all over the world. Rosa damascena Mill., also known as the damask rose, is a well-known scented rose species cultivated to produce essential oil. The essential oils obtained are high in volatile organic compounds (VOCs), which are in demand across the pharmaceutical, food, perfume, and cosmetic industries. Citronellol, nonadecane, heneicosane, caryophyllene, geraniol, nerol, linalool, and phenyl ethyl acetate are the most important components of the rose essential oil. Abiotic factors, including as environmental stress and stress generated by agricultural practises, frequently exert a selective impact on particular floral characteristics, hence influencing the overall quality and quantity of rose products. Additionally, it has been observed that the existence of stress exerts a notable impact on the chemical composition and abundance of aromatic compounds present in roses. Therefore, understanding the factors that affect the biosynthesis of VOCs, especially those representing the aroma and scent of rose, as a response to abiotic stress is important. This review provides comprehensive information on plant taxonomy, an overview of the volatolomics involving aromatic profiles, and describes the influence of abiotic stresses on the biosynthesis of the VOCs in damask rose.
