Porcini mushrooms have evolved with a preference for local adaptation: Research

New Delhi, Nov 22 (ANI): The Dentinger Lab at the Natural History Museum of Utah has published a provocative new paper in the journal New Phytologist that describes their work with the much-beloved mushroom, Boletus edulis, better known by gastronomers worldwide as the porcini. In the paper, Keaton Tremble and Bryn Dentinger, PhD, present a first-of-its-kind genetic survey of porcini mushrooms across the Northern Hemisphere. By evaluating the genetic code of these samples from across the globe, they learned that these delicious fungi evolved in surprising ways contrary to the expectations of many who might think that geographic isolation would be the primary driver for species diversity. In fact, there are regions in the world where porcini maintain their genetic distinctiveness in local ecological niches, even if they are not isolated geographically from other genetic lineages.
