Data from: Genome duplication effects on functional traits and fitness are genetic context and species dependent: studies of synthetic polyploid Fragaria

Na Wei, Zhaokui Du, Aaron Liston & Tia-Lynn Ashman
PREMISE OF THE STUDY Divergence in functional traits and adaptive responses to environmental change underlies the ecological advantage of polyploid plants in the wild. While established polyploids may benefit from combined outcomes of genome doubling, hybridization and polyploidy-enabled adaptive evolution, it remains less clear whether genome doubling alone can drive ecological divergence or whether the outcome is genetically variable.METHODS Using synthetic, colchicine-induced, autotetraploid (4x) plants derived from self-pollinated diploid (2x) seeds, and their colchicine-treated but...
