Valeriana officinalis (valerian), as a nutraceutical herb, is widely used for its sedative and hypnotic properties. It is known that C15 sesquiterpenoid valerenic acid (VA) is active ingredient responsible for pharmacological effects of V. officinalis. To evaluate the effect of methyl jasmonate (MeJA) concentrations (50 and 100 µM) in the modulation of expression patterns of the genes involved ...

Background: Nanoparticles have been applied to medicine, hygiene, pharmacy and dentistry, and will bring significant advances in the prevention, diagnosis, drug delivery and treatment of disease. Green synthesis of metal nanoparticles has a very important role in nanobiotechnology, allowing production of non-toxic and eco-friendly particles.Objectives: Gr...

green synthesis of nanoparticles, as fundamental building blocks of nanotechnology, has recently attracted considerable attention. silver nanoparticles have unique physiochemical, biological and environmental properties which make them useful in a wide range of applications. in the present paper we report our research results on biosynthesis of silver nanoparticles from silver precursor using m...

recent data showed that phenylpropanoid compound, methylchavicol is essential component of iranian cultivars of basil. studying their occurrence during development of plant may help to elucidate the role of phenylpropanoids in plant cell physiology. we followed the phenylpropanoids concentration and the expression of genes related to their biosynthesis during growth and development of two culti...

Since Pseudomonas aeruginosa is capable of biosynthesis of polyhydroxyalkanoic acid (PHA) and rhamnolipids, which contain lipid moieties that are derived from fatty acid biosynthesis, we investigated various fab mutants from P. aeruginosa with respect to biosynthesis of PHAs and rhamnolipids. All isogenic fabA, fabB, fabI, rhlG, and phaG mutants from P. aeruginosa showed decreased PHA accumulat...

the inhibitory activities of aqueous and solvent extracts of twelve selected medicinal plants were evaluated against biosynthesis of aflatoxin b1 (afb1) by aspergillus flavus. the a. flavus was isolated from maize, and aflatoxin b1 biosynthesis was confirmed by comparison with standard afb1 using tlc method. in vivo antiaflatoxigenic efficacies of activity guided solvent extracts were determine...

The biochemical compounds in kenaf leaves and flowers mainly consist of flavonoids, including flavonoid glycosides floral anthocyanins. In the present study, we performed comparative transcriptome analysis using RNA-sequencing identified putative genes involved flower coloration different developmental stages three mutants Baekma (white flower), Jangdae (ivory Bora (purple flower). A total 36.1...

The halophilic unicellular green alga Dunaliella salina is characterized as the distinct tolerance to high salt in field. Normally organism concurrently subjected with and alkali stress, but feature of D. response stress was not investigated before. In this study, we used pH simulate found also showed even grown under at 11.0, cell density chlorophyll biosynthesis. High-throughput transcriptome...

Biosynthesis A cell-free membrane protein synthesis system (CFMPS) with natural or artificial lipid biomembranes is constructed, to effectively synthesize full-length transmembrane proteins by improving the solubility and assisting active structure formation, as described Yuan Lu co-workers in article number 2300575. The CFMPS can be further extended expand toolbox of biosynthesis, paving way f...
