A GWAS −log10p-value of mixed model association against genomic location for flowering onset (solid line indicates a Bonferroni-corrected p-value of 0.05). B Distribution of a strongly-associated non-synonymous SNP in ELF3 among modern A. artemisiifolia populations used in this study. C Genome-wide XtX scans between sampling locations within each range separately. Solid lines indicate Bonferroni-corrected significance derived from XtX p-values; dashed lines indicate the top 1% of genome-wide XtX values. Green highlights represent the top 5% of 10 kbp WZA windows for each scan that are also among the top 5% of EAA WZA windows for at least one environmental variable, with dark green indicating outlier windows shared between North America and Europe. Pale blue bars indicate the location of 15 haploblocks (putative chromosomal inversions) that overlap shared outlier windows. Source data are provided as a Source data file.
