Salinity-responsive hyperaccumulation of flavonoids in Spirodela polyrrhiza, resultant maneuvering in the structure and antimicrobial as well as azo dye decontamination profile of biofabricated zinc oxide nanoentities.

Duckweeds (Spirodela polyrrhiza) are free-floating macrophytes that grow profusely in nutrient-rich waters. Under ideal conditions, they exhibit a rapid growth rate and can absorb a substantial amount of nutrients, macromolecules, and pollutants from bodies of water. Zinc oxide nanoparticles (ZnO NPs) synthesized from plant extracts, particularly under stress conditions, have opened new research avenues in the field of nanotechnology.

Physiological and biomolecular interventions in the bio-decolorization of Methylene blue dye by D. Mitch.

Methylene blue, a cationic dye as a pollutant is discharged from industrial effluent into aquatic bodies.

Photoactivated TiO Nanocomposite Delays the Postharvest Ripening Phenomenon through Ethylene Metabolism and Related Physiological Changes in Fruit.

Capsicum is one of the most perishable fruit which undergo rapid loss of commercial value during postharvest storage. In this experiment our aim is to evaluate the effect of photoactivated TiO nano-particle complexed with chitosan or TiO-nanocomposite (TiO-NC) on extension self-life of fruit and its effect on related morphological, physiological and molecular attributes at room temperature (25 °C).

An updated overview of the physiological and molecular responses of rice to anoxia.

Waterlogging or flooding in agricultural soil constructs a complex abiotic stress-web in crop plants throughout the lowland agricultural system. In rice, a staple grain crop in the world, submergence creates a long-term and recurrent problem for crops withstanding and their succeeding productivity. Therefore, to restore a satisfactory yield instead of a failure of crop in such submerged areas, the analysis of plants' responses is important.
