“…To date, over 1700 VOCs have been identified across more than 90 plant families [ 4 ]. These compounds play valuable roles in attracting pollinators and as a defence mechanism against other animals and microorganisms [ 3 , 5 ], and can also improve the aesthetic value of ornamental plants, benefit human health, and serve as integral components of cosmetics, fragrances and condiments [ 6 , 7 ]. However, the aroma originally typical of Prunus mume was lost when enhancing its resistance to cold by crossing with closely related species of plum and apricot that are tolerant to such conditions.…”

Background Mei (Prunus mume) is the only woody plant in the genus Prunus with a floral fragrance, but the underlying mechanisms of aroma compound biosynthesis are unclear despite being a matter of considerable interest. Results The volatile contents of the petals of two cultivars with significantly different aromas, Prunus mume ‘Xiao Lve’ and Prunus mume ‘Xiangxue Gongfen’, were characterised by GC-MS at different flowering periods, and a total of 44 volatile compounds were detected. Among these, the main substances forming the typical aroma of P. mume were identified as eugenol, cinnamyl acetate, hexyl acetate and benzyl acetate, with variations in their relative concentrations leading to sensory differences in the aroma of the two cultivars. We compiled a transcriptome database at key stages of floral fragrance formation in the two cultivars and used it in combination with differential analysis of floral volatiles to construct a regulatory network for the biosynthesis of key aroma compounds. The results indicated that PmPAL enzymes and PmMYB4 transcription factors play important roles in regulating the accumulation of key biosynthetic precursors to these compounds. Cytochrome P450s and short-chain dehydrogenases/reductases might also influence the biosynthesis of benzyl acetate by regulating production of key precursors such as benzaldehyde and benzyl alcohol. Furthermore, by analogy to genes with verified functions in Arabidopsis, we predicted that three PmCAD genes, two 4CL genes, three CCR genes and two IGS genes all make important contributions to the synthesis of cinnamyl acetate and eugenol in P. mume. This analysis also suggested that the downstream genes PmBGLU18-like, PmUGT71A16 and PmUGT73C6 participate in regulation of the matrix-bound and volatile states of P. mume aroma compounds. Conclusions These findings present potential new anchor points for further exploration of floral aroma compound biosynthesis pathways in P. mume, and provide new insights into aroma induction and regulation mechanisms in woody plants.

“…The differences among phenolic contents in various plants and during different flower development stages could be due to crosslinking among polyphenols and carbohydrates, lipids, and proteins (Kennedy et al, 2000;Jakobek, 2015), changes in petals water content, different enzymes activity during flower open stages, especially phenylalanine ammonia-lyase (PAL), chalcone synthase (CHS), chalcone isomerase (CHI), and flavonol synthase (FLS), petal sap cell pH, minerals profile, and different genes expression (Schmitzer et al, 2009;Burin et al, 2010;Schmitzer et al, 2013;Jia et al, 2016;Lucini et al, 2016;Kanani and Nazarideljou, 2017), and cell membrane stability (Faragher et al, 1987). Our results indicated that based on phenolic compound quantity during flower opening stages, and required to use in the therapeutic process, food additive and/or beauty and cosmetics, using of flowers at different opening stages can be an effective strategy.…”

An experiment was conducted to evaluate the phenolic acids and flavonoids contents from flower bud to flower senescence stages (7 stages) in cut H3O roses every other day. Some phenolic acids (Gallic, Caffeic, Caftaric, Chlorogenic, Chiconic, Coumaric, Sinapic, and Ferulic) and flavonoids (Catechin, Pelargonidin chloride, Cyanidin, Kaempferol, and Quercetin) were detected in the methanolic extract of rose petals by HPLC. Data analysis revealed that Gallic acid content did not significantly (P≤0.05) affects from the flower bud to the senescence stages. However, it's found that Caftaric acid, Chlorogenic acid, Coumaric acid, Ferulic acid, Chiconic acid, Quercetin, and Kaempferol (at P≤0.05), Catechin, Caffeic acid, Sinapic acid, Cyanidin, and Pelargonidin chloride contents (at P≤0.01) significantly affected during flower opening stages. The highest contents of phenolics during development of cut H3O rose flowers were as follow: day 1 [Coumaric acid], day 3 [Caftaric acid, Ferulic acid, and Kaempferol], day 5 [no compound was found], day 7 [Sinapic acid and Cyanidin], day 9 [Chlorogenic acid], day 11 [Chiconic acid and Quercetin], and day 13 [Caffeic acid, Catechin, and Pelargonidin chloride]. The results showed that flower development stages can be suggested to consider the phenolic compounds required to use in the therapeutic process.

“…MeJA treatments induced phenylalanine ammonia-lyase activity, which led to greater accumulation of total phenolic compounds in romaine lettuce (Lactuca sativa L.) and sweet basil (Ocimum basilicum L.) (Kim et al, 2006;Kim et al, 2007). Furthermore, MeJA treatment dramatically increased the levels of some secondary metabolites in Nicotiana attenuata leaves (Keinänen et al, 2001); increasing the relative abundances of methyl benzoate and methyl salicylate in tuberose (Kanani and Nazarideljou, 2017); enhancement certain bioactive compounds, such as ascorbic acid (AsA) and superoxide dismutase (SOD) in 'queen' pineapple PAC tissues (Boonyaritthongchai and Supapvanich, 2017); stimulated the production of phenolic acids, particularly ferulic, chlorogenic, and syringic acids, in Ginkgo biloba (Szewczyk, 2008); induced the biosynthesis of phenolic acids and flavonoids and ginsenoside increasing in Panax ginseng (Ali et al, 2007;Um et al, 2017); and upregulated sorgoleone biosynthesis in sorghum (Uddin et al, 2013) and the production of rosmarinic acid in A. rugosa (Kim et al, 2013).…”
