Rice Plants That Resist Uptake Of Arsenic Could Ease Shortage
Genetically engineered rice plants that resist the uptake of toxic metals could boost production and ease the shortage of this staple crop in Asia, India and Bangladesh, where irrigation with contaminated groundwater has created soils with toxic levels of arsenic. More than 80 percent of the world's population depends on rice as a staple food, but production is dropping in the rice paddies of Bangladesh, parts of India and South and East Asia due to toxic levels of arsenic in the topsoil. Om Parkash of the University of Massachusetts Amherst leads a research team that uses genetic engineering to produce rice plants that block the uptake of arsenic, which could increase production of this valuable crop and provide safer food supplies for millions.
