Scientists probe tomato for key to feeding millions

Australian scientists have found a way to boost crop yields in a move they say could help feed and clothe millions of people in a time of climate crisis. Researchers at the University of Newcastle have found that by knocking out a gene from the genetic code of a tomato plant, it grows sweeter fruit and longer-lasting leaves. Associate Professor Yong-Ling Ruan, from the University's School of Environmental and Life Sciences, says the same technique could be used in a range of plants to boost crop yield and shelf-life.
