Nanoparticles and higher plants
Nanomaterials and nanotechnology have been widely applied in the world in this last decade. Nanotechnology provides the tool and the technological platforms for the study and transformation of biological systems. Few studies have focused on the effects and mechanisms of nanomaterials on plants. The results of these studies have been reported with the aim to provide further insight into connecti...
متن کاملA Glimpse on Silver Nanoparticles Genotoxicity in Higher Plants
Particles with sizes between 1 and 100nm are termed as nanoparticles and are used commercially across several industrial processes. Since last four decades, different varieties of nanostructures are produced and among them the market potential of AgNPs is predicted to rise from recent 0.79 billion to $2.54 billion by 2022 [1]. Different mode of applications of AgNPs makes them bioavailable in t...
متن کاملHigher Plants
Contamination with 2,4,6-trinitrotoluene (TNT) is widespread at sites of past munitions manufacture. It is moderately toxic to plants and highly toxic to some animals. Some aquatic plant species have been observed to promote degradation of TNT. The degradative activity is associated with the root systems but products are found in the surrounding medium. We have examined a range of sixteen gener...

متن کاملSelenium in Higher Plants.
Plants vary considerably in their physiological response to selenium (Se). Some plant species growing on seleniferous soils are Se tolerant and accumulate very high concentrations of Se (Se accumulators), but most plants are Se nonaccumulators and are Se-sensitive. This review summarizes knowledge of the physiology and biochemistry of both types of plants, particularly with regard to Se uptake ...
