Fig. 4
Circos plot illustrating QTL controlling plant height and SNPs exposed to segregation distortion in WM-800. a) Links in the circle represent significant (PFDR ≤ 0.01) di-genic epistatic interactions between independent SNPs. The firm lines connect the epistatically interacting SNPs remaining after forward and backward selection. b) Chromosome 1A to 7D. c) Bars represent the detection rate of SNPs in 100 cross-validation runs during GWAS. The dark grey line represents the detection rate threshold of ≥35%. Coloured bars indicate the 14 significant SNPs identified to control plant height. Red and blue bars symbolize enhancing and reducing effects of the homozygous Julius allele on plant height in WM-800, respectively. d) Segregation distortion regions along the chromosomes. Height of bars symbolized the strength of deviation of the expected Julius allele frequency. Blue and red colours indicate SNPs revealing a decrease and an increase of the Julius allele frequency, respectively. E) Grey connector lines represent the genetic position of the SNP on the wheat chromosome. Position of candidate genes Rht-D1, Rht-B1, Rht24 and Ppd-D1 are indicated outside the Circos plot
