Making new species without sex
Date:6/11/2014

difference: the new plants grew remarkably faster than their parents. Such a fitness advantage is also known from allopolyploid plants in nature and from the superior growth properties of allopolyploid crops. Since the newly generated plants were able to reproduce sexually and their progeny was fertile as well, one can consider them as a new species. The scientists named it Nicotiana tabauca.

"Thus, grafting two species and selecting for horizontal genome transfer could become an interesting method for breeders who could use this approach to create new crop plants with higher yields and improved properties", is the unanimous opinion of the scientists involved in the present study.
