Researchers at Cornell University have cloned an aluminium-tolerance gene into sorghum that could improve yield in aluminium-toxic soils, found mostly in countries in Africa, Asia and South America.
Aluminium is present in acidic soils when the high acid content dissolves clay minerals which can result in limited crop production.
New genetically engineered aluminium-tolerant sorghum varieties are expected to be produced by next year.
