“…F3H and F3'H have received attention. The seed coat, leaf, and stem of Arabidopsis F3H mutant (tt6) showed lower anthocyanin contents than the organs of the wild-type [43]. The seed coat of tt7 mutant (AtF3'H) turned ivory from brown in wild type [44].…”

Fig (Ficus carica L.), a deciduous fruit tree of the Moraceae, provides ingredients for human health such as anthocyanins. However, little information is available on its molecular structure. In this study, the fig peels in the yellow (Y) and red (R) stages were used for transcriptomic analyses. Comparing the R with the Y stage, we obtained 6224 differentially expressed genes, specifically, anthocyanin-related genes including five CHS, three CHI, three DFR, three ANS, two UFGT and seven R2R3-MYB genes. Furthermore, three anthocyanin biosynthetic genes, i.e., FcCHS1, FcCHI1 and FcDFR1, and two R2R3-MYB genes, i.e., FcMYB21 and FcMYB123, were cloned; sequences analysis and their molecular characteristics indicated their important roles in fig anthocyanin biosynthesis. Heterologous expression of FcMYB21 and FcMYB123 significantly promoted anthocyanin accumulation in both apple fruits and calli, further suggesting their regulatory roles in fig coloration. These findings provide novel insights into the molecular mechanisms behind fig anthocyanin biosynthesis and coloration, facilitating the genetic improvement of high-anthocyanin cultivars and other horticultural traits in fig fruits.

“…There are some researches focusing on the relation between floral scent and flower colour, which usually mentioned the regulation of transcription factors (TF). A TF from MYB family, production of anthocyanin pigment 1 (pap1) in Arabidopsis thaliana can activate phenylpropanoids pathway to enhance the emission of phenylpropanoid/benzenoid compounds and accumulate anthocyanin pigments [17,18]. In Petunia hybrids, flower pigment and scent emission are also co-regulated by PH4 [16].…”

A Comparative Analysis of Floral Scent Compounds in Intraspecific Cultivars of Prunus mume with Different Corolla Colours

et al. 2019

Prunus mume is the only fragrant flowering species of Prunus. According to the previous studies, benzyl acetate and eugenol dominate its floral scent. However, the diversity of its floral scents remains to be elucidated. In this work, the floral volatiles emitted from eight intraspecific cultivars of P. mume with white, pink and red flowers, were collected and analyzed using headspace solid-phase microextraction combined with gas chromatograms-mass spectrometry (HS-SPME-GC-MS). In total, 31 volatile compounds were identified, in which phenylpropanoids/benzenoids accounted for over 95% of the total emission amounts. Surprisingly, except for benzyl acetate and eugenol, several novel components, such as benzyl alcohol, cinnamyl acohol, cinnamy acetate, and benzyl benzoate were found in some cultivars. The composition of floral volatiles in cultivars with white flowers was similar, in which benzyl acetate was dominant, while within pink flowers, there were differences of floral volatile compositions. Principal component analysis (PCA) showed that the emissions of benzyl alcohol, cinnamyl alcohol, benzyl acetate, eugenol, cinnamyl acetate, and benzyl benzoate could make these intraspecific cultivars distinguishable from each other. Further, hierarchical cluster analysis indicated that cultivars with similar a category and amount of floral compounds were grouped together. Our findings lay a theoretical basis for fragrant plant breeding in P. mume.

“…Inhibition of the native genes' activities can also enable diversion of metabolic flow, leading to compositional modification of the fragrance spectrum. This route was recently demonstrated in carnation, in which blocking the anthocyanin biosynthetic pathway led to increased methyl benzoate production and flower scent (Zuker et al, 2001). Since both anthocyanins and methyl benzoate originate from the same phenylpropanoid pathway, it was suggested that the flower's enhanced scent production was due to diversion of metabolic flow toward benzoic acid, which is the precursor of methyl benzoate.…”
