An Appraisal of the Field of Metallomics and the Roles of Metal Ions in Biochemistry and Cell Signaling

Neither an understanding of all the essential metals and their interactions nor the functional impacts of the non-essential metals for life, except established toxic elements such as lead, are widely perceived as important in the basic science communities and in the applied sciences such as medicine and engineering.

Genetic Approaches for Iron and Zinc Biofortification and Arsenic Decrease in Oryza sativa L. Grains.

The development of genetically biofortified rice plants with Fe and Zn and with low As accumulation is one of the most promising strategies, since it does not represent an additional cost for farmers, and gives benefits to consumers as well.



A molecular switch in sulfur metabolism to reduce arsenic and enrich selenium in rice grain

The authors show that a gain of function mutant affecting an O -acetylserine (thiol) lyase enhances sulfur and selenium assimilation while reducing arsenic accumulation in grains.

Grain Inorganic Arsenic Content in Rice Managed Through Targeted Introgressions and Irrigation Management

This study suggests that coupling AWD practices targeting a soil VWC of less than or equal to 30% coupled with the use of cultivars developed to possess multiple QTLs that negatively regulate grain iAs concentrations will be helpful in mitigating exposure of iAs from rice consumption.

Soil arsenic but not rice arsenic increasing with arsenic in irrigation water in the Punjab plains of Pakistan

Groundwater irrigation leads to elevated As concentrations in paddy soil of some rice-growing regions of Punjab but does not result in increased uptake of As in basmati rice grains.

Arsenic and cadmium accumulation in rice and mitigation strategies

Background Arsenic (As) and cadmium (Cd) are two toxic elements that have a relatively high risk of transfer from paddy soil to rice grain. Rice is a major dietary source of these two elements for

Rice production threatened by coupled stresses of climate and soil arsenic

It is shown in a greenhouse study that future conditions cause a greater proportion of pore-water arsenite in the rhizosphere of Californian Oryza sativa L. variety M206, grown on Californian paddy soil, which will lead to currently unforeseen losses in paddy rice grain productivity and quality.
