Cisplatin is widely used in the treatment of various types of cancer. However, it could cause severe side effects such as ototoxicity, which greatly limit the clinical application of cisplatin. Forskolin (FSK) is a diterpene derived from the plant Coleus forskohlii, and has been proven an effective drug for cardiovascular disease, diabetes, and asthma because of its anti-oxidant and anti-inflammatory action. Here, we investigated the effects of FSK in cisplatin-induced ototoxicity, and we found that FSK could significantly protect against cisplatin-induced ototoxicity in both cell line and isolated mouse cochlear...

Viroids are highly structured, single-stranded, non-protein-coding circular RNA pathogens that replicate, spread and elicit severe to mild disease symptoms in sensitive host species. The functions of viroids are thought to be due to a molecular element (or elements) embedded within the small RNA molecule that recruits the host factors responsible for transcription, RNA transportation and regulation of gene expression. Coleus blumei viroid 1 (CbVd-1) is distributed worldwide and is known for its characteristic property of having an extremely high frequency of seed transmission...

Flowering in plants is synchronized by both environmental cues and internal regulatory factors. Previous studies have shown that the endophytic fungus Piriformospora indica promotes the growth and early flowering in Coleus forskohlii (a medicinal plant) and Arabidopsis. To further dissect the impact of P. indica on pathways responsible for flowering time in Arabidopsis, we co-cultivated Arabidopsis with P. indica and used RT-qPCR to analyze the main gene regulation networks involved in flowering. Our results revealed that the symbiotic interaction of Arabidopsis with P...

A systematic review and network-meta analysis (NMA) were performed to test significance of the galactagogue effect of fenugreek administrated to lactating women versus other comparators (i.e., placebo/control/other galactagogues). A pairwise comparison for the treatment effect was carried out to generate the forest plot for the NMA. League tables were generated using treatment effect, weighted mean difference (WMD; 95% confidence interval, CI) for all pairwise comparisons, where WMD > 0 favors the column-defining treatment...

Piriformospora indica is an endophytic fungus colonizing roots of a wide variety of plants. Previous studies showed that P. indica promotes early flowering and plant growth in the medicinal plant Coleus forskohlii. To determine the impact of P. indica on flowering time in Arabidopsis, we co-cultivated the plants with P. indica under long day condition. P. indica inoculated Arabidopsis plants displayed significant early flowering phenotype. qRT-PCR analysis of colonized plants revealed an up-regulation of flowering regulatory (FLOWERING LOCUS T, LEAFY, and APETALA1) and gibberellin biosynthetic (Gibberellin 20-Oxidase2, Gibberellin 3-Oxidase1 and Gibberellin requiring1) genes, while the flowering-repressing gene FLOWERING LOCUS C was down regulated...

Anthocyanins have high antioxidant activities, and engineering of anthocyanin biosynthesis in staple crops, such as rice (Oryza sativa L.), could provide health-promoting foods for improving human health. However, engineering metabolic pathways for biofortification remains difficult, and previous attempts to engineer anthocyanin production in rice endosperm failed because of the sophisticated genetic regulatory network of its biosynthetic pathway. In this study, we developed a high-efficiency vector system for transgene stacking and used it to engineer anthocyanin biosynthesis in rice endosperm...

Basil downy mildew (BDM) caused by the oomycete Peronospora belbahrii is a destructive disease of sweet basil (Ocimum basilicum) worldwide. It originated in Uganda in the 1930s and recently spread to Europe, the Middle East, Americas, and the Far East. Seed transmission may be responsible for its quick global spread. The pathogen attacks leaf blades, producing chlorotic lesions with ample dark asexual spores on the lower leaf surface. Oospores may form in the mesophyll of infected leaves. The asexual spores germinate on a wet leaf surface within 2 h and penetrate into the epidermis within 4 h...

Forskolin is a unique structurally complex labdane-type diterpenoid used in the treatment of glaucoma and heart failure based on its activity as a cyclic AMP booster. Commercial production of forskolin relies exclusively on extraction from its only known natural source, the plant Coleus forskohlii , in which forskolin accumulates in the root cork. Here, we report the discovery of five cytochrome P450s and two acetyltransferases which catalyze a cascade of reactions converting the forskolin precursor 13 R -manoyl oxide into forskolin and a diverse array of additional labdane-type diterpenoids...

Development of a phenotyping platform capable of noninvasive biochemical sensing could offer researchers, breeders, and producers a tool for precise response detection. In particular, the ability to measure plant stress in vivo responses is becoming increasingly important. In this work, a Raman spectroscopic technique is developed for high-throughput stress phenotyping of plants. We show the early (within 48 h) in vivo detection of plant stress responses. Coleus ( Plectranthus scutellarioides ) plants were subjected to four common abiotic stress conditions individually: high soil salinity, drought, chilling exposure, and light saturation...

Flavonoids are an important class of secondary metabolites that play various roles in plants such as mediating defense, floral pigmentation and plant-microbe interaction. Flavonoids are also known to possess antioxidant and antimicrobial activities. Coleus forskohlii (Willd.) Briq. (Lamiaceae) is an important medicinal herb with a diverse metabolic profile, including production of a flavonoid, genkwanin. However, components of the flavonoid pathway have not yet been studied in this plant. Chalcone synthase (CHS) catalyses the first committed step of flavonoid biosynthetic pathway...

Cytochrome P450 monooxygenases (CYP450s) are known to play important roles in biosynthesis of all secondary metabolites, including flavonoids. Despite this, few CYP450s have been functionally characterized in model plants and roles of fewer CYP450s are known in non-model, medicinal, and aromatic plants. Our study in Coleus forskohlii indicates that flavone synthase (CYP93B) and flavonoid 3' monooxygenase (CYP706C) are key enzymes positioned at a metabolic junction, to execute the biosynthesis of different sub-classes of flavonoids (flavones, flavonol, anthocynanin, isoflavones etc...
