“…α-Ionone and trans-β-ionone, which were the main aroma-active compounds in present study, have been reported as carotenoid cleavage derivatives of α-carotene and β-carotene in sweet osmanthus (Baldermann et al, 2010;. Han et al (2014) have indicated that α-carotene and β-carotene are abundant in a cultivar of the Aurantiacus group, but nearly non-existent in cultivars of the Albus and Luteus groups. Here we found that the contents and aroma intensities of α-ionone and trans-β-ionone in cultivars of the Albus and Luteus groups were much higher than those in the Aurantiacus group (Tables 1 and 2).…”

Abstract:Objective: Aroma is the core factor in aromatherapy. Sensory evaluation of aromas differed among three sweet osmanthus (Osmanthus fragrans) cultivar groups. The purpose of this study was to investigate the aroma-active compounds responsible for these differences. Methods: Gas chromatography-olfactometry (GC-O) and GC-mass spectrometry (GC-MS) were used to analyze the aroma-active compounds and volatiles of creamy-white ('Houban Yingui', HBYG), yellow ('Liuye Jingui', LYJG), and orange ('Gecheng Dangui', GCDG) cultivars. Results: Seventeen aroma-active compounds were detected among 54 volatiles. trans-β-Ocimene, trans-β-ionone, and linalool, which were major volatiles, were identified as aroma-active, while cis-3-hexenyl butanoate, γ-terpinene, and hexyl butanoate were also aroma-active compounds, although their contents were low. Analysis of the odors was based on the sum of the modified frequency (MF) values of aroma-active compounds in different odor groups. HBYG contained more herb odors, contributed by cis-β-ocimene and trans-β-ocimene, while LYJG had more woody/violet/fruity odors released by trans-β-ionone, α-ionone, and hexyl butanoate. In GCDG, the more floral odors were the result of cis-linalool oxide, trans-linalool oxide, and linalool. Conclusions: Aroma-active compounds were not necessarily only the major volatiles: some volatiles with low content also contributed to aroma. The aroma differences among the three cultivars resulted from variation in the content of different odor groups and in the intensities of aroma-active compounds.

“…Tissue/organ-specific expression analysis can provide vital clues about the function differentiation of the genes in different tissue/organs [38][39][40][41][42][43]. We, thus, analyzed RNA seq data about the expression patterns of 17 pepper STP genes during the development of various tissues (flowers, leaves, fruit and seeds) ( Figure 5).…”

Sugar transporter proteins (STPs) play an important role in plant growth and development and stress resistance. Pepper (Capsicum annuum L.) is a significant economic crop and is widely cultivated worldwide. However, the evolution and the roles of STP genes in the growth and development and in coping with abiotic stresses in pepper are poorly known. Here, we characterized STP gene family in pepper through integration of chromosomal location, gene structure, conserved motif, phylogeny, expression patterns in different tissues and abiotic stresses. Using bioinformatics-based methods, we identified 17 putative STP genes in pepper. Chromosome mapping indicated that they are unevenly distributed on 9 chromosomes and there are tandem duplication events. Gene structure analysis revealed that intron numbers among these CaSTP genes ranged from 2 to 5, except that CaSTP12 and CaSTP13 genes contained no introns. The phylogenetic tree of STP genes from pepper and other plant species revealed that STP genes were grouped into 4 subfamilies, suggesting that these gene subfamilies may have diverged from a single common ancestor prior to the mono-dicot split. Gene expression analysis based on RNA-seq data showed that three genes were expressed constitutively in all the tissues analyzed, implying that these genes might have specific function in pepper. Stress data analysis showed that the expression profiles of some members of the CaSTP gene family were altered under cold, heat, salt and hormone stress conditions. The present results will provide valuable information into the evolutionary relationships and functional divergence of the STP family in the future. ARTICLE HISTORY

The 2-C-methyl-d-erythritol 4-phosphate (MEP) pathway is responsible for the biosynthesis of many crucial secondary metabolites, such as carotenoids, monoterpenes, plastoquinone, and tocopherols. In this study, we isolated and identified 10 MEP pathway genes in the important aromatic plant sweet osmanthus (Osmanthus fragrans). Multiple sequence alignments revealed that 10 MEP pathway genes shared high identities with other reported proteins. The genes showed distinctive expression profiles in various tissues, or at different flower stages and diel time points. The qRT-PCR results demonstrated that these genes were highly expressed in inflorescences, which suggested a tissue-specific transcript pattern. Our results also showed that OfDXS1, OfDXS2, and OfHDR1 had a clear diurnal oscillation pattern. The isolation and expression analysis provides a strong foundation for further research on the MEP pathway involved in gene function and molecular evolution, and improves our understanding of the molecular mechanism underlying this pathway in plants.
