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.
