WASHINGTON (Reuters) - Scientists have found a way to boost the protein, zinc and iron content in wheat, an achievement that could help bring more nutritious food to many millions of people worldwide.
A team led by University of California at Davis researcher Jorge Dubcovsky identified a gene in wild wheat that raises the grain's nutritional content. The gene became nonfunctional for unknown reasons during humankind's domestication of wheat.
Writing in the journal Science on Thursday, the researchers said they used conventional breeding methods to bring the gene into cultivated wheat varieties, enhancing the protein, zinc and iron value in the grain. The wild plant involved is known as wild emmer wheat, an ancestor of some cultivated wheat.
Wheat represents one of the major crops feeding people worldwide, providing about 20 percent of all calories consumed. The World Health Organization has said upward of 2 billion people get too little zinc and iron in their diet, and more than 160 million children under age 5 lack adequate protein.
"We really can produce wheat with more protein and more zinc and iron," Dubcovsky said in an interview. "So if that is grown in a developing country or is used as food aid, it will really provide more of those needed things in places where it's necessary."
