Application of new statistical multi-locus models in sesame. a and b Negative log10 P-values for association of root length (Y-axis) are plotted against SNP positions (X-axis) using the multi-locus models, mrMLM and FASTmrEMMA, respectively; c Negative log10 P-values for association of root length (Y-axis) are plotted against SNP positions (X-axis) using the single-locus model, EMMAX; d and e Negative log10 P-values for association of seed coat color (Y-axis) are plotted against SNP positions (X-axis) using the multi-locus models, mrMLM and FASTmrEMMA, respectively; f Negative log10 P-values for association of seed coat color (Y-axis) are plotted against SNP positions (X-axis) using the single-locus model, EMMAX. For both traits, a horizontal dash–dot line indicates the significant P-value threshold (10-6) and the significant SNPs are highlighted by red color, vertical line indicates overlapped most significant peaks at least in two models; g Venn diagrams showing the shared and uniquely detected significant SNPs by each model for root length GWAS respectively; h, Venn diagrams depicting the shared and uniquely detected significant SNPs by each model for seed coat color GWAS. The phenotypic and genotypic data for this analysis were obtained from 350 sesame accessions and 1,000,000 common SNPs for root length and data from 705 sesame accessions and 1,805,413 common SNPs for seed coat color GWAS study
