Functional diversified kaurene synthase like genes in Isodon rubescens shed light on chemical diversity evolution of diterpenoids in Lamiaceae

ABSTRACT: The Lamiaceae family contains numerous diterpenoids, offering a valuable model system for the study of diterpenoid chemical diversity. In this study we report that the ent-kaurene diterpenoids in I. rubescens have the largest diTPS gene family identified in Lamiaceae. Three genes are predicted to be involved in ent-kaurene diterpenoid synthesis while another two KSL genes are functional enzymes utilizing ent-CPP as a substrate. We also showed the presence of a normal-CPP mediated biosynthesis pathway in I. rubescens and that three KSL genes possessing different domain architectures are involved in this pathway. This study provides new information regarding the understanding of diterpenoid chemical diversity and this compounds’ evolution in the Lamiaceae family.

Multiple genes recruited from hormone pathways partition maize diterpenoid defences.

Project description:Duplication and divergence of primary pathway genes underlie the evolution of plant specialized metabolism; however, mechanisms partitioning parallel hormone and defence pathways are often speculative. For example, the primary pathway intermediate ent-kaurene is essential for gibberellin biosynthesis and is also a proposed precursor for maize antibiotics. By integrating transcriptional coregulation patterns, genome-wide association studies, combinatorial enzyme assays, proteomics and targeted mutant analyses, we show that maize kauralexin biosynthesis proceeds via the positional isomer ent-isokaurene formed by a diterpene synthase pair recruited from gibberellin metabolism. The oxygenation and subsequent desaturation of ent-isokaurene by three promiscuous cytochrome P450s and a new steroid 5α reductase indirectly yields predominant ent-kaurene-associated antibiotics required for Fusarium stalk rot resistance. The divergence and differential expression of pathway branches derived from multiple duplicated hormone-metabolic genes minimizes dysregulation of primary metabolism via the circuitous biosynthesis of ent-kaurene-related antibiotics without the production of growth hormone precursors during defence.

Transcriptome sequencing (RNA-Seq) of HepG2 cells upon treatment of the 10μM Oridonin or DMSO(0.1%)for exploring the metabolic mechanism of Oridonin

Project description:Oridonin is a nature diterpenoid mainly isolated from Chinese herb Rabdosia rubescens and other Isodon species. Nowadays, most of studies focused on the pharmacological effects of oridonin, the metabolism of which remains unclear. In order to investigate the effect of oridonin on metabolism-related genes, we used the second-generation transcriptome sequencing(RNA-seq) to determine the expression changes of each gene in HepG2 cells treated with oridonin.

Expression data from LRK1 060615 transgenic rice and control 9311

Project description:Plant height is a critical constituent of plant architecture. Rice (Oryza sativa) plants have the potential to undergo rapid internodal elongation, which determines plant height. A number of physiological studies have proved that gibberellin is involved in internode elongation. Leucine-rich repeat receptor-like kinases (LRR-RLKs) are the largest subfamily of transmembrane receptor-like kinases in plants. Plant LRR-RLKs play important functions in mediating a variety of cellular processes and regulating responses to environmental signals. LRK1, a PSK receptor homolog, is a member of the LRR-RLK family. In the present study, differences in ectopic expression of LRK1 were consistent with extent of rice internode elongation. Analyses of gene expression demonstrated that LRK1 restricts gibberellin responsiveness during the internode elongation process by down-regulation of the gibberellin biosynthetic gene, ent-KAURENE OXIDASE (OsKO2). Leaf tissues of 6-week-old LRK1 060615 transgenic rice and control 9311 rice (10 plants each) were selected.

Daphnane diterpenoids as potent and tolerable importin-b1 inhibitors to treat castration-resistant prostate cancer [ChIP-Seq]

Project description:Importin-b1, a key member of karyopherins, is composed of 18-20 tandem repeats of the HEAT motif, each of which contains two antiparallel alpha helices linked by a turn. With the help of adaptor protein importin-α, importin-b1 recognizes cargo with NLS in the cytoplasm, and ferries the complex through the NPC into the nucleus. Several studies have shown that importin-b1 is overexpressed in some cancers, especially advanced prostate cancer, and is associated with poor prognosis and drug resistances.Here, the anti-CRPC (castration-resistant prostate cancer) screening of a natural diterpenoid library followed by target fishing led to the identification of a highly potent importin-b1 inhibitor, daphnane diterpenoid DD1(YDGY-3).To further dissect the influence of importin-b1 inhibitors on gene transcription programs, we analyzed H3K27ac chip-seq of C4-2B cells with the treatment of DD1 (YDGY-3).
