Some Plants Duplicate Their DNA to Overcome Adversity
August 1, 2011
Whatever does not kill a plant may actually make it stronger. After being partially eaten by grazing animals, for example, some plants grow bigger and faster and reproduce more successfully than they otherwise would. In a new study, researchers report that one secret to these plants' post-traumatic triumph lies in their ability to duplicate their chromosomes--again and again--without undergoing cell division.
