The genome of the pear (Pyrus bretschneideri Rehd.) (2013, background): “It is estimated that pear and apple must have diverged from each other ;5.4–21.5 MYA (Supplemental Fig.”
Genome duplication in amphibians and fish: an extended synthesis (2011, background): “An intriguing hypothesis based on comparative genomics in plants is that genome duplication events tended to be clustered around the Cretaceous–Tertiary boundary (K–T boundary), when many plant species went extinct (Fawcett et al., 2009), suggesting that polyploids might have had increased survival ”
A synthesis of hornwort diversity: Patterns, causes and future work (2014, background): “; Because genome doubling was noted as a possible advantage in the survival and propagation of vascular plants during the K-T extinction (Fawcett et al. 2009), did the lack of polyploidy in hornworts lead to extinctions in the group?”
Genome sequence and analysis of the tuber crop potato (2011, background): “The recent duplication can therefore be placed at ∼67 million years ago, consistent with the WGD that occurred near the Cretaceous–Tertiary boundary (∼65 million years ago”
Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, positive): “Analysis of ancient polyploidy revealed a clustering of genome duplications around the Cretaceous– Tertiary extinction event approximately 65 million years ago (Fawcett et al., 2009), supporting the view that environmental changes promote polyploid establishment (Oswald and Nuismer, 2011).”
Pure polyploidy: Closing the gaps in autopolyploid research (2017, background): “…age, and type (auto- or allopolyploid) of ancient WGDs has led to key discoveries, such as the polyploid ancestry of all seed plants (Jiao et al., 2011) and the temporal clustering of ancient WGDs around the Cretaceous-Paleogene extinction event (Fawcett et al., 2009; Lohaus & Van de Peer, 2016).”
