A variant of tea tree (Camellia sinensis (L.)) with purple buds and leaves pink flowers can be used as a unique ornamental plant. However, the mechanism flower coloration remains unclear. To elucidate molecular coloration, well anthocyanin accumulation in white flowers, metabolite profiling transcriptome sequencing was analyzed various developmental stages. Results metabolomics analysis revealed that three specific substances could identified, i.e., cyanidin O-syringic acid, petunidin...
Almost all flowers of the tea plant (Camellia sinensis) are white, which has caused few researchers to pay attention anthocyanin accumulation and color changing in flowers. A new purple-leaf cultivar, Baitang purple (BTP) was discovered Mountains Guangdong, whose naturally pink, can provide an opportunity understand metabolic networks flower development In present study, twelve components were identified pink flowers, namely cyanidin O-syringic acid, petunidin 3-O-glucoside, pelargonidin...
Tea (Camelliasinensis var. sinensis) is a widely consumed caffeine-containing beverage, however the Camellia genus also includes other species, which are as tea in their local growing regions. Presently, HPLC analysis assessed 126 unique germplasms belonging to three C. sinensis pubilimba Chang (Csp), gymnogyna (CgC) and crassicolumna (CcC). Theobromine was predominant purine alkaloid all representing over 90% of alkaloids Csp CgC, 50% CcC. Significant variability existed patterns both...
The R2R3-MYB transcription factors (TFs) play several key roles in numerous plant biological processes. Hedychium coronarium is an important ornamental well-known for its elegant flower shape and abundant aroma type. floral of H. due to the presence a large amount terpenes benzenoids. However, less known about role TFs regulatory mechanism production this breed. Herein, we isolate functionally characterize TF HcMYB132, which potentially involved regulating synthesis. Sequence alignment...
Ultraviolet (UV) radiation significantly affects insect life and, as a result, has been widely used to control different invertebrate pests. The current results demonstrate that when Bemisia tabaci first instar nymphs are exposed UV‐A light for 12, 24, 48, and 72 h, their developmental biological parameters negatively affected by exposure; the effect increased with an increase in exposure time. We hypothesized is compatible other agents. Results showed entomopathogenic fungus Cordyceps...
Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. (Xoo) is a highly destructive bacterial disease. Traditional prevention methods have utilized antibiotics to target growth, which has accelerated the emergence of resistant strains. New techniques are developing agents such as type III secretion system (T3SS) inhibitors that virulence factors without affecting growth. To explore novel T3SS inhibitors, series ethyl-3-aryl-2-nitroacrylate derivatives were designed and synthesized....
Ultraviolet-A (UV-A) radiation directly impacts the growth and spread of Bemisia tabaci. However, mechanistic pathways this phenomenon remain unknown. We analyzed B. tabaci transcriptome data after exposure to UV-A for 6 h. The 453 genes were identified whose expression significantly altered in response stress induced by irradiation. Forty up-regulated, while 413 down-regulated. Enrichment analysis using GO, KEGG, Genomes databases revealed that DEGs play key roles antioxidation...
One identified dihydroflavonol 4-reductases (DFR) encoding gene (named as CsDFRa herein) and five putative DFRs CsDFRb1, CsDFRb2, CsDFRb3, CsDFRc CsDFRd) in tea (Camellia sinensis) have been widely discussed recent papers concerning multi-omics data. However, except for CsDFRa, their function biochemical characteristics are not clear. This study aims to compare all CsDFRs preliminarily evaluate function. We investigated the sequences of genes (coding promoter regions) predicted structures...
To elucidate the molecular mechanisms underlying differential metabolism of albino (white), green, and purple pericarp coloration, biochemical profiling transcriptome sequencing analyses were performed on three different tea pericarps, Zhongbaiyihao (Camellia sinensis L. var. Zhongbai), Jinxuan Jinxuan), Baitangziya Baitang). Results analysis revealed that low chlorophyll content chlorophyll/carotene ratio may be basis for characteristics in 'Zhongbaiyihao' pericarp. The differentially...
Intake of a high-fat diet (HFD) is closely related to disorders the intestinal microbiota, which plays key role in pathogenesis obesity. Duyun compound green tea, an ancient Chinese drink, widely consumed reduce weight, although mechanism not clear. In this study, 50 mice were randomly divided into 5 groups: normal control group (CK), HFD model (NK), positive with medicine (YK), low-dose tea (DL), and high-dose (DH). After 4 weeks intervention, feces taken under sterile conditions evaluated...
