Genotype Variation in Rice ( L.) Tolerance to Fe Toxicity Might Be Linked to Root Cell Wall Lignification.

Iron (Fe) is an essential element to plants, but can be harmful if accumulated to toxic concentrations. Fe toxicity can be a major nutritional disorder in rice () when cultivated under waterlogged conditions, as a result of excessive Fe solubilization of in the soil. However, little is known about the basis of Fe toxicity and tolerance at both physiological and molecular level.

Assessing the impacts of sewage sludge amendment containing nano-TiO on tomato plants: A life cycle study.

Increasing evidence indicates the presence of engineered nanoparticles (ENPs) in sewage sludge derived from wastewater treatment. Land application of sewage sludge is, therefore, considered as an important pathway for ENP transfer to the environment. The aim of this work was to understand the effects of sewage sludge containing nano-TiO on plants (tomato) when used as an amendment in agricultural soil.
