“Where these new mutations actually come from is still a mystery，” said Professor Harberd.“They may arise during the regeneration process itself or during the cell divisions in the donor plant that gave rise to the root cells from which the regenerate plants are created.We are planning further research to find out which of these two processes is responsible for these mutations.What we can say is that nature has safely been employing what you might call a ‘cloning’ process in plants for millions of years，and that there must be good evolutionary reasons why these mutations are introduced.”
