Exploring the potential of two Pseudomonas species to produce vincristine from vinblastine via biotransformation.

A biotransformation pair consisting of vinblastine: vincristine present in the Catharanthus roseus plant is of immense pharmacological significance. In this study, we successfully transformed vinblastine into vincristine outside the plant using Pseudomonas aeruginosa 8485 and Pseudomonas fluorescens 2421 and evaluated the antiangiogenic potential of thus produced vincristine through the CAM assay. The toxicity assay showed that both Pseudomonas spp.

Geraniol and citral: recent developments in their anticancer credentials opening new vistas in complementary cancer therapy.

About 10 million people are diagnosed with cancer each year. Globally, it is the second leading cause of death after heart disease, and by 2035, the death toll could reach 14.6 million.

Comparative transcriptional analysis of metabolic pathways and mechanisms regulating essential oil biosynthesis in four elite Cymbopogon spp.

Cymbopogon is an important aromatic and medicinal grass with several species of ethnopharmaceutical importance. The genus is extremely rich in secondary metabolites, monoterpenes like geraniol and citral being principal constituents, also used as biomarker for classification and identification of Cymbopogon chemotypes. In the light of this, present study involved RNA sequencing and comparison of expression profiles of four contrasting Cymbopogon species namely C.

Bioactivity assessment of essential oils of Cymbopogon species using a network pharmacology approach.

Essential oils of Cymbopogon species have wide commercial applications in fragrance, perfumery, and pharmaceuticals as they exhibit a horizon of bioactivities. Here, essential oils of C. flexuosus and C.

Cross-species virus transmission and its pandemic potential.

Background: The majority of pandemics are known to be a result of either bacteria or viruses out of which viruses seem to be an entity of growing concern due to the sheer number of yet unidentified and potentially threatening viruses, their ability to quickly evolve and transform, their ability to transfer and change from one host organism to another and the difficulty in creating safe vaccines on time.

Main Body: The present review attempts to bring forth the potential risks, prevention and its impact on the global society in terms of sociological and economic parameters. Taking hindsight from previously as well as ongoing current viral epidemics, this article aims to draw a concrete correlation between these viruses in terms of their origin, spread and attempts to compare how much they can affect the population.

Effect of ZnO Nanoparticles on Growth and Biochemical Responses of Wheat and Maize.

Zinc is an essential element that is also renowned for widespread contamination and toxicity at high concentrations. The present study was carried out to analyze the responses induced by lower, as well as higher, doses of zinc (0-200 mg/L), in the form of zinc oxide nanoparticles (ZnO NPs) in wheat and maize, for a period of 21 days. Accumulation of zinc increases with increasing Zn doses in both wheat and maize, with higher doses being in wheat (121 mg/kg in root and 66 mg/kg in shoot) than in maize (95 mg/kg in root and 48 mg/kg in shoot).

An update on the progress of microbial biotransformation of commercial monoterpenes.

Monoterpenes, a class of isoprenoid compounds, are extensively used in flavor, fragrance, perfumery, and cosmetics. They display many astonishing bioactive properties of biological and pharmacological significance. All monoterpenes are derived from universal precursor geranyl diphosphate.

Marker-assisted transfer of gene to develop soft grain wheat cultivars.

Grain softness has been a major trait of interest in wheat because of its role in producing flour suitable for making high-quality biscuits, cookies, cakes and some other products. In the present study, marker-assisted backcross breeding scheme was deployed to develop advanced wheat lines with soft grains. The Australian soft-grained variety Barham was used as the donor parent to transfer the puroindoline grain softness gene - to the Indian variety, DBW14, which is hard grained and has genes.

Rheological evaluations and molecular marker analysis of cultivated bread wheat varieties of India.

The aim of this study was to screen Indian cultivated wheat varieties and list out the parameters/genes required to be improved for an end-product. Therefore, 30 Indian wheat varieties under cultivation by farmers were screened for 14 physico-chemical and rheological parameters, sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) for high molecular weight glutenin subunits (HMW-GS), DNA based molecular markers for low molecular weight glutenin subunits (LMW-GS) and puroindolines () genes. Based on grain texture, sedimentation value, farinographic, alveographic, HMW-GS and LMW-GS and biscuit making parameters, HS490 was found to be a highly suited for biscuit and soft wheat products.

Study on Phytochemical Composition, Antibacterial and Antioxidant Properties of Different Parts of Alstonia scholaris Linn.

Purpose: To evaluate phytochemical composition, antibacterial and antioxidant properties of methanolic extracts of different parts viz., leaves, follicles and latex of Indian devil tree (Alstonia scholaris Linn.) R.

Essential oil biosynthesis and regulation in the genus Cymbopogon.

Essential oils distilled from Cymbopogon species are of immense commercial value as flavors and fragrances in the perfumery, cosmetics, soaps, and detergents and in pharmaceutical industries. Two major constituents of the essential oil, geraniol and citral, due to their specific rose and lemon like aromas are widely used as flavors, fragrances and cosmetics. Citral is also used for the synthesis of vitamin A and ionones (for example, beta-ionone, methyl ionone).

Geranyl acetate esterase controls and regulates the level of geraniol in lemongrass (Cymbopogon flexuosus Nees ex Steud.) mutant cv. GRL-1 leaves.

Essential oil isolated from lemongrass (Cymbopogon flexuosus) mutant cv. GRL-1 leaves is mainly composed of geraniol (G) and geranyl acetate (GA). The proportion of G and GA markedly fluctuates during leaf development.

An account of cloned genes of Methyl-erythritol-4-phosphate pathway of isoprenoid biosynthesis in plants.

Isoprenoids, also known as terpenoids, are biosynthesized by the condensation of the two C5 unit isopentenyl diphosphate (IPP) and isomer dimethylallyl diphosphate (DMAPP). Generally, plants use two separate pathways plastidial Methyl-erythritol-4-phosphate (MEP) and cytosolic acetate-mevalonate (MVA) pathways for formation of IPP. The genes, enzymes and intermediates of the MEP pathway have been unravelled in plants over the past few years.
