Lonicera macranthoides Hand.-Mazz (L. macranthoides) is a medicinal herb that is widely distributed in South China. The developmental stage and corolla dehiscence of the flower are the important factors affecting the quality of medicinal ingredients. However, neither the regulatory mechanism controlling chlorogenic acids biosynthesis in L. macranthoides nor the molecular basis of effect of corolla dehiscence on the quality of medicinal materials is fully understood. In this study, metabolomics and transcriptomics were used to analyze the metabolic and transcriptional differences of two different cultivars closed bud type (Bt), and flowering type (Ft), as well as the effect of jasmonic acid methyl ester (MeJA) on chlorogenic acids (CGAs) biosynthesis. In total, large number of differentially expressed genes (DEGs) and differentially accumulated metabolites (DAMs) were filtered among three lines of samples. Gene metabolite correlation analyses revealed a ‘core set’ of 30 genes and 54 genes that were strongly correlated with CGAs biosynthesis and regulating the flowering, respectively. Quantitative real-time polymerase chain reaction results proved the alterations in the expression levels of genes encoding the pathways involved in CGAs biosynthesis. The ion abundances of CGAs were most significantly increased, while some of the CGAs derived and Caffeoyl-CoA-derived substances showed the most largely reduced abundances in the closed bud type (Bt) compared to the flowering type (Ft). MeJA may leads to the activation of downstream genes in CGAs biosynthesis pathway. Overall, there were significant differences in the transcriptional and metabolic levels of CGAs biosynthesis pathway in flower buds of different flowering cultivars. The redirection of metabolic flux may contribute to increased accumulation of CGAs. However, whether MeJA and flowering have direct effects on the accumulation of CGAs needs further studied. These researches effectively expanded the functional genomic library and provide new insights into CGAs biosynthesis in L. macranthoides.

“…The dry buds or open flowers constitute the medicinal components of Chinese medicinal L. japonica , which are used for the prevention and treatment of severe acute respiratory syndromes, H1N1 influenza, and hand-foot-and-mouth disease [ 2 ]. Pharmacological studies have also demonstrated that L. japonica flowers possess antibacterial, anti-inflammatory, anticancer, anti-diabetic, anti-oxidative and antiviral properties, as well as various other pharmacological effects [ 3 – 6 ]. Consequently, L. japonica is referred to as a “plant antibiotic” [ 7 ]; its adaptability is very robust and it is widely distributed across the nation [ 7 ].…”

Background Lonicera japonica Thunb. ( L. japonica ) has the functions of clearing away heat and detoxifying, broad-spectrum antibacterial and anti-virus, etc. More than 70% of anti-inflammatory and cold Chinese patent medicines contain L. japonica . Trichomes comprise specialized multicellular structures that have the capacity to synthesize and secrete secondary metabolites and protect plants from biotic and abiotic stresses. The extraction of trichome secretions has great commercial value. However, little is known about the trichome formation mechanism in L. japonica . Therefore, the study of trichome development between different varieties provides a basis for selecting suitable planting resources. Results Here, we present a genome-wide comparative transcriptome analysis between two L. japonica cultivars, toward the identification of biological processes and functional gene activities that occur during flowering stage trichome development. In this study, the density and average lengths of flower trichomes were at their highest during three-green periods (S2). Using the Illumina RNA-Seq method, we obtained 134,304 unigenes, 33,733 of which were differentially expressed. In an analysis of 40 differentially expressed unigenes (DEGs) involved in trichome development, 29 of these were transcription factors. The DEGs analysis of plant hormone signal transduction indicated that plant growth and development may be independent of gibberellin (GA) and cytokinine (CTK) signaling pathways, and plant stress may be independent of jasmonic acid (JA) and ethylene (ET) signaling pathways. We screened several genes involved in the floral biosynthesis of odors, tastes, colors, and plant hormones, and proposed biosynthetic pathways for sesquiterpenoid, triterpenoid, monoterpenoid, flavonoid, and plant hormones. Furthermore, 82 DEGs were assigned to cell cycles and 2616 were predicted as plant resistance genes (PRGs). Conclusions This study provides a comprehensive characterization of the expression profiles of flower development during the seven developmental stages of L. japonica , thereby offering valuable insights into the molecular networks that underly flower development in L. japonica .
