“…In cashew apple ( Anacardium occidentale L.) juice, the thermal degradation of carotenoids produces an aroma profile of 33 active odor volatiles, such as 1,2,3,5-tetramethylbenzene, naphthalene, and p-xylene ( Queiroz et al, 2014 ). Carotenoids are also involved in floral scent in Osmanthus fragrans ( Baldermann et al, 2010 ; Xi et al, 2021 ). β-ionone, a carotenoid derivative, is produced by the flowering plants Rosa moschata , Thymus vulgaris , Viola tricolor , Medicago marina , and Myrtus communis ( Paparella et al, 2021 ).…”

Floral scents and fruit aromas are crucial volatile organic compounds (VOCs) in plants. They are used in defense mechanisms, along with mechanisms to attract pollinators and seed dispersers. In addition, they are economically important for the quality of crops, as well as quality in the perfume, cosmetics, food, drink, and pharmaceutical industries. Floral scents and fruit aromas share many volatile organic compounds in flowers and fruits. Volatile compounds are classified as terpenoids, phenylpropanoids/benzenoids, fatty acid derivatives, and amino acid derivatives. Many genes and transcription factors regulating the synthesis of volatiles have been discovered. In this review, we summarize recent progress in volatile function, composition, biosynthetic pathway, and metabolism regulation. We also discuss unresolved issues and research perspectives, providing insight into improvements and applications of plant VOCs.

“…In Osmanthus fragrans, 2-(4-chlorophenylthio)-triethylamine hydrochloride (CPTA) induces OfMYB43 expression. Transient overexpression of OfMYB43 significantly promotes the expression of phytoene desaturase (PDS), zeta-carotene isomerase (ZISO), lycopene epsilon-cyclase (LCYE), and CCD4, leading to increased accumulation of beta-branch carotenoids (Xi et al 2021).…”

Flower color and scent, crucial qualitative characteristics of ornamental plants, display extensive variation. These distinct pigments and scents play a key role in attracting specific pollinators. While previous research primarily delved into the synthetic regulatory mechanisms of individual traits and their respective attraction to insects, recent studies unveil an interconnectedness between flower color and scent through transcriptional regulatory networks. Moreover, evidence suggests that both color and scent actively contribute to insect attraction. This review summarizes the co-regulation and synthesis of pigments and scents, highlighting their pivotal roles in pollinator attraction. The insights provided will serve as valuable references for applications in metabolic engineering, novel variety breeding, and insect and pest detection and management.

“…The OfWRKY3 is a positive regulator of the OfCCD4 gene, and might partly account for the biosynthesis of beta-ionone in O. fragrans. the OfMYB1 may acted as a transcriptional activator to regulate expression of OfPAL gene [42][43][44] (Figure 4). Genes related to anthocyanin synthesis mainly include CHS, CHI, F3H, F3′H, F3′5′H, DFR, ANS, and UGT [45][46][47].…”

Osmanthus fragrans is an evergreen shrub or tree of the Oleaceae family with a long history of cultivation in Asian countries and is one of the ten traditionally famous flowers in China, with important cultural and economic value. The unique floral color and fragrance of O. fragrans are formed by a variety of endogenous metabolites that distinguish it from other flowers and exhibit extraordinary ornamental value. However, many studies on the flower color and fragrance of this plant have been mainly based on bioactive extracts and physiological characteristics, leading to a notable lack of molecular machinery and systematic research. In this review, recent advances in bioactive ingredients associated with the underlying regulatory mechanisms, as well as the prospect for industrial utilization, are comprehensively presented and critically evaluated. In particular, the isolated components and essential genes required for flower color and fragrance are also well summarized, which will provide a scientific basis for molecular breeding for ornamental applications and facilitate the discovery of novel natural products for the future industrial development of O. fragrans. In prospect, we plan to use genetic research and high-throughput omics to analyze the genes related to the flower color and fragrance of O. fragrans, and at the same time, we will hybridize and breed excellent O. fragrans varieties that are resistant to low temperature.
