Polyploidy – A Path to Greater Adaptation to Changing Environmental Conditions
Led by Dr. Rie Shimizu-Inatsugi, a research team at UZH, together with colleagues from the United States and Japan, investigated the genetic consequences of polyploidization—an important evolutionary force driving biological diversity.
The study closes a long-standing knowledge gap by showing for the first time which epigenetic and transcriptomic responses occur immediately after polyploidization and determine successful speciation.
