Unravelling the role of stress in the evolution of polyploidy
Despite the existence of many polyploid species, whole genome duplications (WGDs) are not evident in their genome. The consensus is that WGDs have contributed to polyploid species but took place at specific times during evolution under stressful conditions or environmental changes. The EU-funded DOUBLE-TROUBLE project wishes to address why environmental changes affect polyploidy and is working under the hypothesis that polyploid species have a survival or fitness advantage compared to non-polyploids. Scientists will run evolutionary experiments, and combined with modelling, they will decipher the adaptive potential of polyploids under stressful conditions or during times of climate change.
