Fig. 4

a, b Manhattan plots of GWAS of DM resistance (a) and DM incidence (b). Gray horizontal dashed lines indicate the Bonferroni-corrected significance thresholds of GWAS (α = 0.05 and α = 1, respectively). c Major associated region with both DM resistance and DM incidence, with genes and the known marker Pfs-1 plotted. Gray track indicates the LD (r2) between the lead SNP (Peak1) of DM resistance and other individual SNPs in this region. A kinase receptor gene, MKK7, six NBS-LRR genes, and the RAR1 gene are highlighted in blue, brown, and green, respectively. d Allele frequencies of the top two lead SNPs for the DM resistance (Peak1 and Peak2) and DM incidence (Peak3 and Peak4) in the spinach nature population. Source data are provided as a Source Data file.
