Project description:Transcriptome profiling of alkaloid biosynthesis induced opium poppy
| PRJNA238882 | ENA
Project description:MicroRNAs (miRNA) are ~21 nucleotide long, small endogenous non-coding RNAs that functioning in regulation of gene expression found in many eukaryotes. In this study, small RNA libraries of opium poppy from four different tissues (leaf, root, capsule, stem) were sequenced using high-throughput next generation Illumina sequencing (Solexa) technology to investigate potential mode of actions of miRNAs in alkaloid biosynthesis. A total of 27 opium poppy miRNAs which have roles in regulation of alkaloid biosynthesis were identified in this study.

A total of 27 opium poppy miRNAs which have roles in regulation of alkaloid biosynthesis were identified in this study. A six chip study using miRNA isolated from four separate tissues (capsule, leaf, stem, root). small RNA libraries of opium poppy tissues were sequenced using high-throughput next generation Illumina sequencing (Solexa) technology to investigate potential mode of actions of miRNAs in alkaloid biosynthesis. Furthermore, the novel opium poppy miRNAs were also confirmed by a direct small RNA cloning strategy. The microarray platform were performed to measure and analyze the mirnome of the different opium poppy tissues.

Project description:Regulation of alkaloid biosynthesis by miRNAs in opium poppy
| PRJNA264856 | ENA
Project description:In the current study, RNA sequencing based transcriptional profiling was used to elaborate the combinatorial effect of berberine, a well-known antibacterial alkaloid, and thymol, a monoterpenic phenol, on the Staphylococcus aureus transcriptome.

Project description:We analyzed the transcriptome of A. acutangulus roots by deep RNA sequencing to dig TAs biosynthetic genes. KOG (Eukaryotic Orthologous Groups) and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment analyses identified 48 unigenes referring to the tropane, piperidine and pyridine alkaloid biosynthesis, 145 unigenes presumably involved in distribution of arginine to TAs biosynthesis, and 86 unigenes referring to the terpenoid backbone biosynthesis. Furthermore, 82 unigenes annotated as cytochrome P450 family members seemed to be involved in secondary metabolism pathways. Previously unknown TAs biosynthetic genes in A. acutangulus, which encode littorine mutase/monooxygenase (CYP80F1) and diamine oxidase (DAO), were identified by this study.

Project description:This dataset belongs to a set of three RNA-Seq experiments that were carried out to study the regulation of monoterpenoid indole alkaloid production in the medicinal plant Catharanthus roseus. For this dataset, C. roseus hairy roots overexpressing the well-known MIA biosynthesis regulator ORCA3 were analyzed by RNA-Seq. As control, C. roseus hairy roots expressing GUS were used. Each analyzed sample consisted of an independent hairy root line; three hairy root lines per construct were analyzed.

Project description:Sampangine, a plant-derived alkaloid found in the Annonaceae family, exhibits strong inhibitory activity against the opportunistic fungal pathogens Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus. In the present study, transcriptional profiling experiments coupled with the analysis of mutants were performed in an effort to elucidate its mechanism of action. Using Saccharomyces cerevisiae as a model organism, we show that sampangine produces a transcriptional response indicative of hypoxia, altering the expression of genes known to respond to low oxygen conditions. Several additional lines of evidence obtained suggest that these responses could involve effects on heme. First, the hem1 deletion mutant lacking the first enzyme in the heme biosynthetic pathway showed increased sensitivity to sampangine, and exogenously supplied hemin partially rescued the inhibitory activity of sampangine in wild-type cells. In addition, heterozygous mutants with deletions in genes involved in five out of eight steps in the heme biosynthetic pathway showed increased susceptibility to sampangine. Furthermore, spectral analysis of pyridine extracts indicated significant accumulation of free porphyrins in sampangine-treated cells. Transcriptional profiling experiments were also performed in C. albicans to investigate the response of a pathogenic fungal species to sampangine. Taking into account the known differences in the physiological responses of C. albicans and S. cerevisiae to low oxygen, significant correlations were observed between the two transcription profiles suggestive of heme-related defects. Our results indicate that the antifungal activity of the plant alkaloid sampangine is due, at least in part, to perturbations in the biosynthesis or metabolism of heme.
