Data for: Genome material costs and functional tradeoffs in the autopolyploid Solidago gigantea (Giant Goldenrod) series

Premise of study: Increased genomic “material costs” of nitrogen (N) and phosphorus (P) atoms inherent to organisms with larger genome sizes (GS) has been proposed to limit growth under nutrient scarcities and promote growth under nutrient enrichments. Such responsiveness may reflect a nutrient-dependent diploid versus polyploid advantage that could have vast ecological and evolutionary implications, but direct evidence that material costs increase with ploidy-level and/or influence cytotype-dependent growth, metabolic, and/or resource-use tradeoffs is limited.
Methods: We grew diploid, auto-tetraploid, and auto-hexaploid Solidago gigantea plants under one of four ambient and enriched N:P treatments and measured traits related to material costs, primary and secondary metabolism, and resource-use.
Key results: Relative to diploids, polyploids invested more N and P into cells and tetraploids grew more following N-enrichments, suggesting that material costs increase with ploidy-level.
