Effects of polystyrene nanoplastics exposure on in vitro-grown Stevia rebaudiana plants.

Nanoplastics (NPs) as environmental contaminants have received increased attention in recent years. Numerous studies have suggested possible negative effects of plants exposure to NPs, but more data are needed with various plants under different exposure conditions to clarify the underlying phytotoxicity mechanisms. In this study, we investigated the effect of polystyrene nanoplastics (PSNPs; 28.

Gadolinium Accumulation and Toxicity on In Vitro Grown A Case-Study on Gadobutrol.

Gadolinium-based contrast agents are molecular complexes which are extensively used for diagnostic purposes. Apart from their tremendous contribution to disease diagnostics, there are several issues related to their use. They are extremely stable complexes and potential contaminants of surface and ground waters, an issue which is documented worldwide.

The effect of 100-200 nm ZnO and TiO nanoparticles on the in vitro-grown soybean plants.

Engineered nanomaterials are increasingly used in everyday life applications and, in consequence, significant amounts are being released into the environment. From soil, water, and air they can reach the organelles of edible plants, potentially impacting the food chain and human health. The potential environmental and health impact of these nanoscale materials is of public concern.

Soybean Callus-A Potential Source of Tocopherols.

In vitro cultures have been used as an effective means to achieve a high level of secondary metabolites in various plants, including soy. In this study, the contents of α-, γ-, and δ- tocopherol were quantified in soybean callus, and their amounts were compared to those of soybeans cultivated using the conventional tillage system with three weed controls (respectively without herbicide and with two variants of herbicide). Soybean callus was produced using Murashige and Skoog 1962 (MS) medium supplemented with 0.

Micropropagation, Genetic Fidelity and Phenolic Compound Production of L.

An efficient micropropagation protocol for L. was developed in this study. The in vitro rhubarb plants obtained in the multiplication stage (proliferation rate: 5.
