How apple detectives solved the mystery of an ancient tree and rewrote the history of fruit

Cameron Peace, a tree-fruit geneticist at Washington State University, made an extraordinary discovery when analyzing DNA from an apple tree found on an abandoned Maine farm - it turned out to be a lost progenitor that had been influencing American apple varieties for hundreds of years. So this wasn't just any old tree; this was essentially a missing link in the genetic family tree of North American apples, discovered through collaboration between Peace's laboratory and the Maine Organic Farmers and Gardeners Association. Now, here's the thing - this matters enormously because most American apples come from just 15 commercial varieties, which makes the entire crop vulnerable to diseases like fire blight and powdery mildew. By recovering the genes from this ancient tree, scientists can breed back traits that our ancestors may have lost - characteristics that could protect modern apple crops against emerging threats.
