Formation and Persistence of a Co-Occurring Mixed Cytotype Autopolyploid System

Project summary:

The impact of multiple origins on the genetics and ecology of a naturally occurring multi-cytotype autopolyploid system has largely been overlooked. Multiple formations of both the triploid and tetraploid cytotypes of Galax urceolata (Diapensiaceae) make this the ideal system to investigate relatedness among cytotypes and cytotype-specific soil chemistry/microbial associations.
