Abstract Salvia miltiorrhiza is a model medicinal plant with significant economic and value. Its roots produce group of diterpenoid lipophilic bioactive components, termed tanshinones. Biosynthesis regulation tanshinones has attracted widespread interest. However, the methylome S. not been analysed regulatory mechanism DNA methylation in tanshinone production largely unknown. Here we report sin...

The EARLY MATURITY 8 (EAM8) gene of barley is homologous to the FLOWERING 3 (ELF3) in Arabidopsis, as loss-of-function mutations this circadian clock promote rapid flowering. A previous study demonstrated that early flowering phenotype a hulless barley, Lalu, was due allele eam8.l carrying an alternative splicing mutation intron led retention. In present study, we verified encoded truncated pro...

Bacterial pathogens need to scavenge iron from their host for growth and proliferation during infection. They have evolved several strategies to do this, one being the biosynthesis and excretion of small, high-affinity iron chelators known as siderophores. The biosynthesis of siderophores is an important area of study, not only for potential therapeutic intervention but also to illuminate new e...

Co-culture engineering is an emerging approach for microbial biosynthesis of a variety of biochemicals. In this study, E. coli-E. coli co-cultures were developed for heterologous biosynthesis of the natural product naringenin. The co-cultures were composed of two independent E. coli strains dedicated to functional expression of different portions of the biosynthetic pathway, respectively. The c...

The biotrophic fungus Ustilago maydis causes smut disease in maize with characteristic tumor formation and anthocyanin induction. Here, we show that anthocyanin biosynthesis is induced by the virulence promoting secreted effector protein Tin2. Tin2 protein functions inside plant cells where it interacts with maize protein kinase ZmTTK1. Tin2 masks a ubiquitin-proteasome degradation motif in ZmT...

Aliphatic glucosinolates (GLSs) are derived from chain-elongated methionine produced by an iterative three-step process, known to be evolutionarily recruited from leucine biosynthesis. The divergence of homologous genes between two pathways is mainly linked to the alterations in biochemical features. In this study, it was discovered that a distinct pattern of histone modifications is associated...

Cholesterol biosynthesis serves as a central metabolic hub for numerous biological processes in health and disease. A detailed, integrative single-view description of how the cholesterol pathway is structured and how it interacts with other pathway systems is lacking in the existing literature. Here we provide a systematic review of the existing literature and present a detailed pathway diagram...

Triadimefon (Bayleton), a widely used triazole-type fungicide, affects gibberellin (GA) biosynthesis and 14 alpha-demethylase in sterol biosynthesis. The present study revealed that the phenotype of Arabidopsis treated with triadimefon resembled that of a brassinosteroid (BR)-biosynthesis mutant, and that the phenotype was rescued by brassinolide (BL), the most active BR, partly rescued by GA, ...

Biosynthesis of the anticancer drug Taxol involves 19 enzymatic steps from the universal diterpenoid progenitor geranylgeranyl diphosphate derived by the plastidial methylerythritol phosphate pathway for isoprenoid precursor supply. To gain further insight about Taxol biosynthesis relevant to the improved production of this drug and to draw inferences about the organization, regulation, and ori...

Alliaria petiolata (garlic mustard, Brassicaceae) contains the glucosinolate sinigrin as well as alliarinoside, a γ-hydroxynitrile glucoside structurally related to cyanogenic glucosides. Sinigrin may defend this plant against a broad range of enemies, while alliarinoside confers resistance to specialized (glucosinolate-adapted) herbivores. Hydroxynitrile glucosides and glucosinolates are two c...
