Responses to lead stress in : insights into antioxidative defence mechanisms and changes in flavonoids profile.

Lead (Pb) induces oxidative stress in plants, which results in different responses, including the production of antioxidants and changes in the profile of secondary metabolites. In this study, the responses of Scrophularia striata exposed to 250mgL-1 Pb (NO3 )2 in a hydroponic environment were determined. Growth parameters, oxidative and antioxidative responses, redox status, and the concentration of Pb were analysed in roots and shoots.

Silver nanoparticles in plant health: Physiological response to phytotoxicity and oxidative stress.

Silver nanoparticles (AgNPs) have gained significant attention in various fields due to their unique properties, but their release into the environment has raised concerns about their environmental and biological impacts. Silver nanoparticles can enter plants following their exposure to roots or via stomata following foliar exposure. Upon penetrating the plant cells, AgNPs interact with cellular components and alter physiological and biochemical processes.

Silver Nanoparticle's Toxicological Effects and Phytoremediation.

The advancement in nanotechnology has brought numerous benefits for humans in diverse areas including industry, medicine, and agriculture. The demand in the application of nanomaterials can result in the release of these anthropogenic materials into soil and water that can potentially harm the environment by affecting water and soil properties (e.g.

The potential of medicinal plant extracts in improving the phytoremediation capacity of Solanum nigrum L. for heavy metal contaminated soil.

This study focused on the effects of eight medicinal plant extracts on Solanum nigrum L. potential to accumulate Cd and Pb from soil. These medicinal plants were common and relatively cheap.

Type-specific impacts of silver on the protein profile of tomato ().

Silver nanoparticles (AgNPs) are particularly among the widely used nanomaterials in medicine, industry, and agriculture. The small size and large surface area of AgNPs and other nanomaterials result in their high reactivity in biological systems. To better understand the effects of AgNPs on plants at the molecular level, tomato () seedlings were exposed to 30 mg/L silver in the form of nanoparticle (AgNPs), ionic (AgNO), or bulk (Ag) in 50% Hoagland media for 7 days.

The mechanism of chelator improved the tolerance and accumulation of poplar to Cd explored through differential expression protein based on iTRAQ.

Appropriate chelator may increase plant tolerance and accumulation for Cd in soil, but its molecular mechanism is unclear. In this experiment, the technology of isobaric tags for relative and absolute quantitation (iTRAQ) was used to compare the differential expression proteins (DEPs) and differential expression genes (DEGs) characteristics of poplar accumulating Cd combined with EDTA and/or EGTA. The results showed that the Cd concentrations, biomasses and activities of antioxidant enzymes of poplar were significantly increased in the treatments of chelator addition compared to the T The number of co-intersecting specific proteins of T/CK, T/T, T/T and T/T was 49.

Exposure of tomato () to silver nanoparticles and silver nitrate: physiological and molecular response.

Silver nanoparticles (AgNPs) are among the most widely used nanomaterials, with applications in sectors as diverse as communications, energy, medicine, and agriculture. This diverse application of AgNPs increases the risk of the release of these materials into the environment and raises the potential for transfer into plants and, subsequently, the human body. To better understand the effects of NPs in agricultural systems, this study investigates plant physiological and molecular responses upon exposure to AgNPs in comparison to silver nitrate (AgNO).

Leucanthemum vulgare lam. crude oil phytoremediation.

Sites with crude oil pollution have been successfully treated using phytoremediation, but expanding the range of plants that can be used and understanding how exposure impacts the plants are two areas of study that are important to continue. Leucanthemum vulgare has been shown to grow well under a variety of stressful conditions. To examine L.

Leucanthemum vulgare lam. germination, growth and mycorrhizal symbiosis under crude oil contamination.

Oil contamination of soil limits plants' access to water and nutrients. Leucanthemum vulgare colonized by mycorrhizae could provide an effective tool in remedying oil contamination. Seeds of L.
